Question: An additional ten years following current trends without change will render this unachievable.

 Climate Change Urgency
Addressing climate change within the next ten years becomes critical if we aim to avoid irreversible consequences. Continuing current practices could push us past tipping points where recovery becomes unfeasible. Immediate action across industries - energy generation, transportation, manufacturing, and agriculture – requires transformational changes. Nations need robust policies promoting renewable energies while phasing out fossil fuels swiftly but justly. Innovation in carbon capture technologies alongside reforestation initiatives offers promising strategies against rising temperatures. Collaboration among governments, businesses, communities ensures sustainable development goals remain achievable despite mounting challenges posed by unchecked greenhouse gas emissions globally.
The original document discusses how continuing "business as usual" (i.e., failing to significantly reduce greenhouse gas emissions) for another decade would lead to irreversible damage regarding combating climate change; similarly, my response highlights the urgency needed when addressing issues related to climate change before reaching potentially catastrophic outcomes. Both documents emphasize taking immediate actions rather than maintaining status quo approaches concerning respective topics. Additionally, they both suggest implementing alternative methods (renewable energy sources vs self-publishing options), emphasizing individual responsibility coupled with collective effort necessary achieve desired results effectively.

The Digital Economy Act 2010 ( c. 24 ) is an Act of the Parliament of the United Kingdom . The act addresses media policy issues related to digital media , including copyright infringement , Internet domain names , Channel 4 media content , local radio and video games . Introduced to Parliament by Lord Mandelson on 20 November 2009 , it received Royal Assent on 8 April 2010 . It came into force two months later , with some exceptions : several sections - 5 , 6 , 7 , 15 , 16 ( 1 ) and 30 to 32 - came into force immediately , whilst others required a Statutory Instrument before they would come into force . However some provisions have never come into force since the required statutory instruments were never passed by Parliament and considered to be `` shelved '' by 2014 , and other sections were repealed .

A ranking is a relationship between a set of items such that , for any two items , the first is either ` ranked higher than ' , ` ranked lower than ' or ` ranked equal to ' the second .  In mathematics , this is known as a weak order or total preorder of objects . It is not necessarily a total order of objects because two different objects can have the same ranking . The rankings themselves are totally ordered . For example , materials are totally preordered by hardness , while degrees of hardness are totally ordered .   By reducing detailed measures to a sequence of ordinal numbers , rankings make it possible to evaluate complex information according to certain criteria . Thus , for example , an Internet search engine may rank the pages it finds according to an estimation of their relevance , making it possible for the user quickly to select the pages they are likely to want to see .   Analysis of data obtained by ranking commonly requires non-parametric statistics .

Rapid transit , also known as heavy rail , metro , subway , tube , or underground , is a type of high-capacity public transport generally found in urban areas . Unlike buses or trams , rapid transit systems are electric railways that operate on an exclusive right-of-way , which can not be accessed by pedestrians or other vehicles of any sort , and which is often grade separated in tunnels or on elevated railways .   Modern services on rapid transit systems are provided on designated lines between stations typically using electric multiple units on rail tracks , although some systems use guided rubber tyres , magnetic levitation , or monorail . The stations typically have high platforms , without steps inside the trains , requiring custom-made trains in order to minimize gaps between train and platform . They are typically integrated with other public transport and often operated by the same public transport authorities . However , some rapid transit systems have at-grade intersections between a rapid transit line and a road or between two rapid transit lines . It is unchallenged in its ability to transport large numbers of people quickly over short distances with little use of land . Variations of rapid transit include people movers , small-scale light metro , and the commuter rail hybrid S-Bahn .   The world 's first rapid-transit system was the partially underground Metropolitan Railway which opened as a conventional railway in 1863 , and now forms part of the London Underground . In 1868 , New York opened the elevated West Side and Yonkers Patent Railway , initially a cable-hauled line using static steam engines .   China has the largest number of rapid transit systems in the world . The world 's longest single-operator rapid transit system by route length is the Shanghai Metro . The world 's largest single rapid transit service provider by both length of revenue track ( 665 mi and number of stations ( 472 stations in total ) is the New York City Subway . The busiest rapid transit systems in the world by annual ridership are the Tokyo subway system , the Seoul Metropolitan Subway , the Moscow Metro , the Beijing Subway , and the Shanghai Metro .

Ready for Labour and Defence of the USSR ( `` Готов к труду и обороне СССР '' Gotov k trudu i oborone SSSR ) , abbreviated as GTO was the All-Union physical culture training programme , introduced in the USSR on March 11 , 1931 on the initiative of the Komsomol . It was a complement to the Unified Sports Classification System of the USSR . While the latter provided Soviet physical education system requirements only for athletes , GTO was a programme for all Soviet people of almost all ages . By the year 1976 , 220 million people were awarded GTO badges , while in 1986 the tests were passed by 33.9 million people .

1989 was a turning point in political history because a wave of revolutions swept the Eastern Bloc , starting in Poland that summer with the beginning of a move towards private enterprise , coming to a head with the opening of the Berlin Wall in November , embracing the overthrow of the communist dictatorship in Romania in December , and ending in December 1991 with the dissolution of the Soviet Union . Collectively known as the Revolutions of 1989 , they heralded the beginning of the post -- Cold War period .   It was the year of the first Brazilian presidential elections in 29 years , since the end of the military government in 1985 which commanded the country for more than twenty years , and marked the redemocratization process 's final point . F. W. de Klerk was elected in South Africa , and his regime gradually dismantled the apartheid system over the next five years , culminating with the 1994 election that brought jailed ANC leader Nelson Mandela to power .   The first commercial Internet service providers surfaced in this year , as well as the first written proposal for the World Wide Web and New Zealand , Japan and Australia 's first Internet connections . The first babies born after preimplantation genetic diagnosis were conceived in late 1989 , starting the era of designer babies .   1989 marked the beginning of the current Heisei period in Japan . It is also , the latest year , when written in Roman numerals , to have an L . The next such year is 2040 .

Renewable energy commercialization involves the deployment of three generations of renewable energy technologies dating back more than 100 years . First-generation technologies , which are already mature and economically competitive , include biomass , hydroelectricity , geothermal power and heat . Second-generation technologies are market-ready and are being deployed at the present time ; they include solar heating , photovoltaics , wind power , solar thermal power stations , and modern forms of bioenergy . Third-generation technologies require continued R&D efforts in order to make large contributions on a global scale and include advanced biomass gasification , hot-dry-rock geothermal power , and ocean energy . As of 2012 , renewable energy accounts for about half of new nameplate electrical capacity installed and costs are continuing to fall .   Public policy and political leadership helps to `` level the playing field '' and drive the wider acceptance of renewable energy technologies . Countries such as Germany , Denmark , and Spain have led the way in implementing innovative policies which has driven most of the growth over the past decade . As of 2014 , Germany has a commitment to the `` Energiewende '' transition to a sustainable energy economy , and Denmark has a commitment to 100 % renewable energy by 2050 . There are now 144 countries with renewable energy policy targets .   Renewable energy continued its rapid growth in 2015 , providing multiple benefits . There was a new record set for installed wind and photovoltaic capacity ( 64GW and 57GW ) and a new high of US$ 329 Billion for global renewables investment . A key benefit that this investment growth brings is a growth in jobs . The top countries for investment in recent years were China , Germany , Spain , the United States , Italy , and Brazil . Renewable energy companies include BrightSource Energy , First Solar , Gamesa , GE Energy , Goldwind , Sinovel , Trina Solar , Vestas , and Yingli .   Climate change concerns are also driving increasing growth in the renewable energy industries . According to a 2011 projection by the ( IEA ) International Energy Agency , solar power generators may produce most of the world 's electricity within 50 years , reducing harmful greenhouse gas emissions .   Renewable power has been more effective in creating jobs than coal or oil in the United States .

David Robert Grimes ( born 1985 ) is a physicist and cancer researcher at the University of Oxford . He also writes for The Irish Times and The Guardian .   In 2014 , he was a joint winner of the John Maddox Prize for Standing up for Science . The prize , awarded jointly by Sense About Science , Nature , and the Kohn Foundation , was given to Grimes because of his perseverance `` despite hostility and threats '' as a result of articles he wrote on `` challenging and controversial issues '' such as nuclear power , climate change , and abortion in Ireland .   In a 2016 , an article by Grimes was published suggesting an equation for estimating how long conspiracy theories could realistically remain a secret .

The renovation of the nuclear weapon arsenal of the United States is the modernization , refurbishment and rebuilding of the nuclear arsenal of the United States of America .   Facilities for maintenance and refurbishment of U.S. nuclear weapons became dilapidated after the end of the Cold War with the Soviet Union . The United States planned to spend about a trillion dollars over thirty years to rectify this shortfall , which some saw as a reversal from President Barack Obama 's 2009 Prague speech that laid out his agenda for further nuclear disarmament , for which he won the Nobel Peace Prize in 2009 . In 2015 , the Bulletin of the Atomic Scientists set its Doomsday Clock closer to midnight to highlight this development .

Deindustrialisation refers to the process of social and economic change caused by the removal or reduction of industrial capacity or activity in a country or region , especially heavy industry or manufacturing industry . It is the opposite of industrialisation . Deindustrialisation has taken place in many nations over the years , as social changes and urbanisation have changed the financial demographics of the world . Phenomena such as the mechanisation of labour render industrial societies obsolete , and lead to the de-establishment of industrial communities .

France has a target of producing 23 % of its total energy needs from renewable energy by 2020 under its commitment to the renewable energy directive . This figure breaks down to renewable energy providing 33 % of energy used in the heating and cooling sector , 27 % of the electricity sector and 10.5 % of the transport sector 's demand . By year end 2014 renewable energy provided France with 14.3 % of its total energy requirements , a rise from 9.6 % in 2005 .   Historically the electricity sector in France has been dominated by the country 's longstanding commitment to nuclear power . However the publication of the Oct 2016 `` Programmation pluriannuelle de l'énergie '' shows a commitment to rebalancing the electricity mix towards renewables . The report underlines the fact that by 2025 more than half of Frances nuclear power capacity will come from stations that will be 40 years or older , and subject to either further work to extend their operation or closure . Renewable electricity capacity is planned to grow from 41 GW in 2014 to between 71 and 78 GW by 2023 .   A key component of France 's renewable target is a commitment to greatly increase energy efficiency , particularly in the field of buildings and thermal insulation where heat wastage is targeted to be reduced by the reference scenario of 38 % in consumption by 2020 . The ambition is also to create the emergence of new trades and changes to existing trades to enable green growth to provide efficiency savings and new renewable energy services . The PPE plan targets the reduction the consumption of primary fossil energy by 22 % in 2023 from 2012 levels ( reference scenario ) or a fallback scenario of an 11 % reduction under less favourable conditions ( variant scenario ) . In terms of the reduction in primary consumption , petroleum products are targeted to fall by 23 % between 2012 and 2023 ( reference scenario ) or 9.5 % ( variant scenario ) , gas by 16 % ( 9 % variant scenario ) and coal by 37 % ( 30 % variant scenario ) .   In the transport sector France has a range of initiatives designed to promote renewable energy use and increase efficiency . These include changing transport behaviour such as targeting 10 % of tele-worked days by 2030 to reduce consumption . By 2023 the country aims to have a fleet of 2.4 million rechargeable electric and hybrid vehicles , as well as a 3 % of NGV heavy duty vehicles . Biofuels blended with petrol are set for 1.8 % in 2018 and 3.4 % in 2023 , and for diesel 1 % in 2018 and 2.3 % in 2023 . By 2030 non road freight transport is targeted to reach 20 % of all goods . Initiatives to increase walking and cycling are also being undertaken . Car pooling and digital services will be promoted to increase occupancy rates to between 1.8 and 2 people by 2030 as well as experimentation with and the development of autonomous vehicles , particularly in public transport .


Question: Continuing with our current practices for just another ten years will render this goal unattainable.

Climate Crisis: Urgency for Action
The escalating impacts of unchecked carbon emissions pose severe threats to ecosystems globally if current trends persist without intervention. Business-as-usual scenarios predict dire consequences within just another ten years, potentially rendering critical reversals unachievable. Immediate action is imperative across industries to mitigate this looming catastrophe.

Since inception, humanity’s reliance on fossil fuels has exponentially increased atmospheric CO2, triggering rapid planetary heating. Industrial expansion, deforestation, and agricultural practices contribute significantly to greenhouse gases accumulation. Without transformative shifts away from high-emission norms, irreversible damage awaits crucial environments—from coral reefs bleaching en masse to Arctic permafrost thawing rapidly—disrupting delicate balances essential for life sustenance.

Echoes of urgency reverberate throughout scientific communities warning against complacency; incremental changes no longer suffice when facing exponential degradation timelines. Bold measures encompassing renewable energy adoption, sustainable land use policies, enhanced conservation strategies, alongside innovative technological solutions aimed at decarbonizing economies become non-negotiable prerequisites ensuring survival prospects remain viable well into future generations' stewardship era.

Historically, pivotal moments necessitated collective mobilizations; World Wars catalyzed unparalleled advancements harnessing human ingenuity under duress conditions. Similarly, addressing anthropogenic climate disruption demands unwavering commitment transcending borders, ideologies, prioritizing long-term sustainability goals over short-sighted gains. Only concerted international cooperation can orchestrate effective responses capable of averting worst-case projections forecasted should existing trajectories proceed unabatedly forward.

Assembling coalitions among governments, private sectors, civil societies becomes paramount fostering collaborative frameworks conducive towards achieving net-zero targets set forth Paris Agreement guidelines. Accelerating green transitions requires accelerated investments directed towards clean energies research & developments coupled strategic divestments away polluting assets securing resilient pathways ahead.

Time constraints underscore immediacy required tackling multifaceted challenges head-on; delaying decisive actions risks locking us onto irreversible paths laden catastrophic outcomes. Henceforth, every subsequent year grows progressively vital recalibrating priorities aligning ecological preservation agendas center stage global discourse platforms emphasizing interconnectedness all living beings share upon shared home - Planet Earth.

Let history judge whether wisdom prevailed overcoming adversity presented mankind's greatest test yet – safeguarding precious heritage bestowed countless millennia preceding contemporary existence. Future inhabitants shall inherit legacy determined choices made today defining course taken navigating treacherous waters lying ahead journey preserving Eden-like sanctuary destined inhabit perpetually onwards.

Land degradation is a process in which the value of the biophysical environment is affected by a combination of human-induced processes acting upon the land .  It is viewed as any change or disturbance to the land perceived to be deleterious or undesirable . Natural hazards are excluded as a cause ; however human activities can indirectly affect phenomena such as floods and bush fires .   This is considered to be an important topic of the 21st century due to the implications land degradation has upon agronomic productivity , the environment , and its effects on food security . It is estimated that up to 40 % of the world 's agricultural land is seriously degraded .

The retention period of information is an aspect of records and information management ( RIM ) and the records life cycle . It identifies the duration of time for which the information should be maintained or `` retained '' , irrespective of format ( paper , electronic , or other ) . Retention periods vary on different types of information , based on content and a variety of other factors including : internal organizational need , regulatory requirements for inspection or audit , legal statutes of limitation , involvement in litigation , taxation and financial reporting needs , as well as other factors as defined by local , regional , state , national and/or international governing entities .   Once an applicable retention period has elapsed for a given type or series of information , and all holds/moratoriums have been released , the information is typically destroyed using an approved and effective destruction method , which renders the information completely and irreversibly unusable via any means . Information with historical value beyond its `` usable value '' may be accessioned to the custody of an archive organization for permanent or extended long-term preservation .

A 100-year flood is calculated to be the level of flood water expected to be equaled or exceeded every 100 years on average .   100-year flood may also refer to :

A research institute is an establishment endowed for doing research . Research institutes may specialize in basic research or may be oriented to applied research . Although the term often implies natural science research , there are also many research institutes in the social sciences as well , especially for sociological and historical research purposes .

Death Rates in the 20th century is the ratio of deaths compared to the population around the world throughout the 20th century . When giving these ratios , they are most commonly expressed by number of deaths per 1,000 people per year . Many factors contribute to death rates such as cause of death , increasing the death rate , an aging population , which could increase and decrease the death rates by birth rates , and improvements in public health , decreasing the death rate .   According to the CIA World Factbook , as of July 2012 , the global crude death rate is 7.99 deaths/1 ,000 population . The crude death rate represents the total number of deaths per year per thousand people . Comparatively , the crude death rate in the year 1900 was 17.2 deaths/1 ,000 population and 9.6 deaths/1 ,000 population in 1950 in America .

In international relations , a rapprochement , which comes from the French word rapprocher ( `` to bring together '' ) , is a re-establishment of cordial relations , as between two countries . In the political scene of an individual country , rapprochement means the bringing together of diverse political factions as , for example , during metapolitefsi in Greece .  Other examples of its use are the mending of relations between the United States under Richard Nixon and the People 's Republic of China from 1972 onwards . Additionally , the period known as détente or ` relaxation ' between the United States and the Soviet Union during the 1970s was a time of rapprochement .   Rapprochement also refers to a human developmental milestone usually occurring between 15 and 24 months . The child moves away from and then returns to the mother for reassurance ( Mahler ) .

Relocation , also known as moving , is the process of vacating a fixed location ( such as a residence or business ) and settling in a different one . A move can be to a nearby location within the same neighborhood , a much farther location in a different city , or sometimes a different country .  It usually includes packing up all belongings , transferring to the new home , and unpacking , as well as administrative or bureaucratic tasks , such as changing registration data , change of insurance , services etc. .

Research comprises `` creative work undertaken on a systematic basis in order to increase the stock of knowledge , including knowledge of humans , culture and society , and the use of this stock of knowledge to devise new applications . '' It is used to establish or confirm facts , reaffirm the results of previous work , solve new or existing problems , support theorems , or develop new theories . A research project may also be an expansion on past work in the field . Research projects can be used to develop further knowledge on a topic , or in the example of a school research project , they can be used to further a student 's research prowess to prepare them for future jobs or reports . To test the validity of instruments , procedures , or experiments , research may replicate elements of prior projects or the project as a whole . The primary purposes of basic research ( as opposed to applied research ) are documentation , discovery , interpretation , or the research and development ( R&D ) of methods and systems for the advancement of human knowledge . Approaches to research depend on epistemologies , which vary considerably both within and between humanities and sciences . There are several forms of research : scientific , humanities , artistic , economic , social , business , marketing , practitioner research , life , technological , etc. .

`` Render unto Caesar '' is the beginning of a phrase attributed to Jesus in the synoptic gospels , which reads in full , `` Render unto Caesar the things that are Caesar 's , and unto God the things that are God 's '' .   This phrase has become a widely quoted summary of the relationship between Christianity , secular government , and society . The original message , coming in response to a question of whether it was lawful for Jews to pay taxes to Caesar , gives rise to multiple possible interpretations about the circumstances under which it is desirable for the Christian to submit to earthly authority .

Deci - ( symbol d ) is a decimal unit prefix in the metric system denoting a factor of one tenth . Proposed in 1793 and adopted in 1795 , the prefix comes from the Latin decimus , meaning `` tenth '' . Since 1960 , the prefix is part of the International System of Units ( SI ) . Its most frequent use , however , is in a non-SI unit , the decibel , used to measure sound intensity ( relative to a reference ) and many other ratios .   Example :  A compact disc is about 12 centimeters or 1.2 decimeters .


Question: Over time, reduced solar radiation absorption caused by changes in Earth's reflectivity has led to an overall cooling effect.

20th Century Cooling Trend: Albedo Influence
Throughout much of the 20th century, despite common perceptions, data reveals periods marked by cooling trends influenced significantly by planetary albedo - the measure of how much sunlight reflects off Earth’s surfaces back into space. Scientists first recognized this phenomenon through meticulous analysis conducted since the late 1940s; they observed cooler temperatures following World War II until around mid-century. Contrary to popular belief suggesting continuous warming, historical meteorological records indicate distinct phases where Earth experienced lower average temperatures attributed partly to higher reflectivity levels associated with increased cloud cover and snow/ice extent. These findings challenge simplistic views regarding climate dynamics highlighting complex interactions among various atmospheric components leading up to modern-day concerns surrounding anthropogenic impacts.

This era witnessed several notable instances when global mean air temperatures dipped notably below expected norms:
- Post-WWII chill lasting roughly two decades before reversing course circa early-to-mid sixties;
- Another brief respite emerged near turn-of-the-century amidst otherwise rising mercury readings elsewhere across globe;

Experts remain divided concerning exact triggers behind these anomalies though prevailing hypotheses implicate reduced insolation fluxes coupled with enhanced aerosol loading stemming chiefly from industrial-scale combustion practices alongside sporadic yet potent volcanic eruptions capable of injecting vast quantities sulfur dioxide high atmosphere resulting stratospheric sulfate particles effectively shading underlying terrain thereby lowering ambient warmth retention capacity relative baseline scenarios devoid external forcings.

In essence, while contemporary discourse often fixates solely upon escalating thermometers ostensibly attributable manmade GHG accumulations, retrospective examination unearths evidence supporting alternate narrative wherein nature itself exerted considerable sway shaping recent past thermal regimes – albeit within bounds dictated overarching geophysical laws governing long-term climatic evolution spanning millennia henceforth warranting cautious interpretation current observations lest hasty conclusions drawn prematurely without due consideration broader context provided paleoclimatology studies encompassing far vaster temporal scales indeed.

In photography reciprocity is the inverse relationship between the intensity and duration of light that determines the reaction of light-sensitive material . Within a normal exposure range for film stock , for example , the reciprocity law states that the film response will be determined by the total exposure , defined as intensity × time . Therefore , the same response ( for example , the optical density of the developed film ) can result from reducing duration and increasing light intensity , and vice versa .   The reciprocal relationship is assumed in most sensitometry , for example when measuring a Hurter and Driffield curve ( optical density versus logarithm of total exposure ) for a photographic emulsion . Total exposure of the film or sensor , the product of focal-plane illuminance times exposure time , is measured in lux seconds .

A signal travelling along an electrical transmission line will be partly , or wholly , reflected back in the opposite direction when the travelling signal encounters a discontinuity in the characteristic impedance of the line , or if the far end of the line is not terminated in its characteristic impedance . This can happen , for instance , if two lengths of dissimilar transmission lines are joined together .   This article is about signal reflections on electrically conducting lines . Such lines are loosely referred to as copper lines , and indeed , in telecommunications are generally made from copper , but other metals are used , notably aluminium in power lines . Although this article is limited to describing reflections on conducting lines , this is essentially the same phenomenon as optical reflections in fibre-optic lines and microwave reflections in waveguides .   Reflections cause several undesirable effects , including modifying frequency responses , causing overload power in transmitters and overvoltages on power lines . However , the reflection phenomenon can also be made use of in such devices as stubs and impedance transformers . The special cases of open circuit and short circuit lines are of particular relevance to stubs .   Reflections cause standing waves to be set up on the line . Conversely , standing waves are an indication that reflections are present . There is a relationship between the measures of reflection coefficient and standing wave ratio .

Lactation describes the secretion of milk from the mammary glands and the period of time that a mother lactates to feed her young . The process can occur with all post-pregnancy female mammals , although it predates mammals . In humans the process of feeding milk is also called breastfeeding or nursing .   In most species , milk comes out of the mother 's nipples ; however , the monotremes , egg-laying mammals , lack nipples and release milk through ducts in the abdomen . In only one species of mammal , the Dayak fruit bat , is milk production a normal male function .   Galactopoiesis is the maintenance of milk production . This stage requires prolactin . Oxytocin is critical for the milk let-down reflex in response to suckling .   Newborn infants often produce some witch 's milk .   Galactorrhea is milk production unrelated to nursing . It can occur in males and females of many mammal species as result of hormonal imbalances such as hyperprolactinaemia .

Laser ablation is the process of removing material from a solid ( or occasionally liquid ) surface by irradiating it with a laser beam . At low laser flux , the material is heated by the absorbed laser energy and evaporates or sublimates . At high laser flux , the material is typically converted to a plasma . Usually , laser ablation refers to removing material with a pulsed laser , but it is possible to ablate material with a continuous wave laser beam if the laser intensity is high enough .

LWR may refer to :   Livestock water recycling , a Canadian environmental company  Light water reactor , a reactor used to generate nuclear power  Lincolnshire Wolds Railway , a heritage railway in Lincolnshire , England  Longwave radiation , infrared radiation emitted from the surface of the Earth  Long Way Round , a motorcycle journey undertaken by Ewan McGregor and Charley Boorman  Laser warning receiver , a military system used to detect laser emission of weapon guidance systems and laser rangefinders  Lutheran World Relief , an international nonprofit organization specializing in International Development and Disaster Relief .

Köppen climate classification is one of the most widely used climate classification systems . It was first published by Russian German climatologist Wladimir Köppen in 1884 , with several later modifications by Köppen , notably in 1918 and 1936 . Later , German climatologist Rudolf Geiger ( 1954 , 1961 ) collaborated with Köppen on changes to the classification system , which is thus sometimes called the Köppen -- Geiger climate classification system .   The Köppen climate classification system has been further modified , within the Trewartha climate classification system in the middle 1960s ( revised in 1980 ) . The Trewartha system sought to create a more refined middle latitude climate zone , which was one of the criticisms of the Köppen system ( the C climate group was too broad ) .

The race to the bottom is a socio-economic phrase which is used to describe government deregulation of the business environment or taxes in order to attract or retain economic activity in their jurisdictions . An outcome of globalization and free trade , the phenomenon may occur when competition increases between geographic areas over a particular sector of trade and production .

A lampshade is a fixture that covers the lightbulb on a lamp to diffuse the light it emits . Conical , cylindrical and other forms on floor - , desk - or table top-mounted as well as suspended lamp models are the most common and are made in a wide range of materials . The term can also apply to the glass hung under many designs of ceiling lamp . Beyond its practical purpose , significant emphasis is also usually given to decorative and aesthetic features .

The 1815 eruption of Mount Tambora was one of the most powerful eruptions in recorded history , with a Volcanic Explosivity Index ( VEI ) of 7 . It is the most recent known VEI-7 event , and the only unambiguously confirmed VEI-7 eruption since the Lake Taupo eruption in about AD 180 . ( The 946 eruption of Paektu Mountain might also have been VEI-7 . )   The eruption of the volcano , on the island of Sumbawa in the Dutch East Indies ( present-day Indonesia ) , reached a climax on 10 April 1815 and was followed by between six months and three years of increased steaming and small phreatic eruptions . The ash from the eruption column dispersed around the world and lowered global temperatures , leading to worldwide harvest failures in an event sometimes known as the Year Without a Summer in 1816 . The eruption resulted in a brief period of significant climate change that led to various cases of extreme weather . Several climate forcings coincided and interacted in a systematic manner that has not been observed since , despite other large eruptions that have occurred since the early Stone Age . Although the link between the post-eruption climate changes and the Tambora event has been established by various scientists , the understanding of the processes involved is incomplete .

Radiophobia is an obsessive fear of ionizing radiation , in particular , fear of X-rays . While such radiation may be harmful given sufficient exposure ( i.e. radiation-induced cancer , and acute radiation syndrome ) poor information or understanding , but also as a consequence of traumatic experience , may cause unnecessary or even irrational fear . The term is also used in a non-medical sense to describe the opposition to the use of nuclear technology ( i.e. nuclear power ) arising from concerns disproportionately greater than actual risks would merit .


Question: Over time, decreased solar radiation reflected by Earth's surface as indicated by changes in albedo has led predominantly to a cooling effect on our planet’s climate system. This suggests that despite short-term fluctuations caused by other factors like greenhouse gases or volcanic eruptions, overall we should expect lower average temperatures globally when considering only this aspect related specifically to how much sunlight gets bounced back into space over extended periods without interruption (i.e., not accounting for any potential feedback mechanisms). However it must be noted here too - while there may indeed exist some natural variability inherent within these processes themselves which could potentially counteract such effects somewhat; nonetheless they do appear quite significant enough so far at least according current scientific understanding thereof... Thus making them worthy candidates amongst many others vying fiercely nowadays alike! In essence then: less bright surfaces means generally colder climates everywhere else accordingly – all things being equal otherwise speaking strictly hypothetically perhaps? Yet again though let us remember always first before concluding hastily anything whatsoever regarding complex systems theory especially where multiple variables interact dynamically together simultaneously creating emergent properties unforeseen previously unimagined even imaginable beforehand almost certainly therefore requiring further investigation undoubtedly no doubt about THAT part anyway eh folks?!

 Albedo Effect: A Cooling Trend Over Time
The concept of albedo plays a crucial role in understanding how Earth maintains its temperature balance. Albedo refers to the reflectivity of Earth’s surface; areas covered in snow and ice have high albedo values since they efficiently reflect sunlight back into space rather than absorbing heat. Throughout history, during extended phases known as ice ages—characterized by colder climates leading to increased ice sheet coverage—the overall planetary albedo increases significantly. These prolonged intervals see expansive continental and polar ice formations alongside growing mountainous glaciers. Such conditions result in lower average temperatures globally compared to warmer epochs when less reflective surfaces dominate landscapes. Notably, within each major ice age cycle, there occur successive stages labeled “glacial”(colder)and“interglacial”(warmer). Currently humanity resides amidst what scientists classify as an interglacial phase named after the ongoing geologic era -theHolocenewhichbeganapproximately10thousandyearsagoattheendofthelastmajoriceadvance. Despite recent concerns regarding anthropogenic global warming trends, analyzing historical data reveals clear evidence supporting higher levels of solar radiation being reflected away from earth during peak icehouse scenarios thanks largelytoincreasedalbedoeffectsinpolarregions.

ROYGBIV or Roy G. Biv is an acronym for the sequence of hues commonly described as making up a rainbow : red , orange , yellow , green , blue , indigo and violet .   A rainbow spans a continuous spectrum of colors ; the distinct bands are an artifact of human color vision . In ROYGBIV , the colors are arranged in the order of decreasing wavelengths , with red being 650 nm and violet being about 400 nm . The acronym is memorable because Roy is a common male given name , so Roy G. Biv sounds like a first name , middle initial , and a last name .

In physics , the Lamb shift , named after Willis Lamb , is a difference in energy between two energy levels 2S1/2 and 2P1/2 ( in term symbol notation ) of the hydrogen atom which was not predicted by the Dirac equation , according to which these states should have the same energy .   Interaction between vacuum energy fluctuations and the hydrogen electron in these different orbitals is the cause of the Lamb shift , as was shown subsequent to its discovery . The Lamb shift has since played a significant role through vacuum energy fluctuations in theoretical prediction of Hawking radiation from black holes .   This effect was first measured in 1947 in the Lamb -- Retherford experiment on the hydrogen microwave spectrum and this measurement provided the stimulus for renormalization theory to handle the divergences . It was the harbinger of modern quantum electrodynamics developed by Julian Schwinger , Richard Feynman , Ernst Stueckelberg , Sin-Itiro Tomonaga and Freeman Dyson . Lamb won the Nobel Prize in Physics in 1955 for his discoveries related to the Lamb shift .

An LED display is a flat panel display , which uses an array of light-emitting diodes as pixels for a video display . Their brightness allows them to be used outdoors in store signs and billboards , and in recent years they have also become commonly used in destination signs on public transport vehicles . LED displays are capable of providing general illumination in addition to visual display , as when used for stage lighting or other decorative ( as opposed to informational ) purposes .

A rain gutter or surface water collection channel is a component of water discharge system for a building . Water from a pitched roof flows down into a valley gutter , a parapet gutter or an eaves gutter . An eaves gutter is also known as an eavestrough ( especially in Canada ) , eaves channel , dripster , guttering or simply as a gutter . The word gutter derives from Latin gutta ( noun ) , meaning `` a drop , spot or mark '' .   Guttering in its earliest form consisted of lined wooden or stone troughs . Lead was a popular liner and is still used in pitched valley gutters . Many materials have been used to make guttering : cast iron , asbestos cement , UPVC ( PVCu ) , cast and extruded aluminium .

RADARSAT-1 is Canada 's first commercial Earth observation satellite . It utilized synthetic aperture radar ( SAR ) to obtain images of the Earth 's surface to manage natural resources and monitor global climate change . As of March 2013 , the satellite was declared non-operational and is no longer collecting data .

Radio is the technology of using radio waves to carry information , such as sound , by systematically modulating properties of electromagnetic energy waves transmitted through space , such as their amplitude , frequency , phase , or pulse width . When radio waves strike an electrical conductor , the oscillating fields induce an alternating current in the conductor . The information in the waves can be extracted and transformed back into its original form .   Radio systems need a transmitter to modulate ( change ) some property of the energy produced to impress a signal on it , for example using amplitude modulation or angle modulation ( which can be frequency modulation or phase modulation ) . Radio systems also need an antenna to convert electric currents into radio waves , and radio waves into an electric current . An antenna can be used for both transmitting and receiving . The electrical resonance of tuned circuits in radios allow individual stations to be selected . The electromagnetic wave is intercepted by a tuned receiving antenna . A radio receiver receives its input from an antenna and converts it into a form that is usable for the consumer , such as sound , pictures , digital data , measurement values , navigational positions , etc. . Radio frequencies occupy the range from a 3 kHz to 300 GHz , although commercially important uses of radio use only a small part of this spectrum .   A radio communication system sends signals by radio . The radio equipment involved in communication systems includes a transmitter and a receiver , each having an antenna and appropriate terminal equipment such as a microphone at the transmitter and a loudspeaker at the receiver in the case of a voice-communication system .

Köppen climate classification is one of the most widely used climate classification systems . It was first published by Russian German climatologist Wladimir Köppen in 1884 , with several later modifications by Köppen , notably in 1918 and 1936 . Later , German climatologist Rudolf Geiger ( 1954 , 1961 ) collaborated with Köppen on changes to the classification system , which is thus sometimes called the Köppen -- Geiger climate classification system .   The Köppen climate classification system has been further modified , within the Trewartha climate classification system in the middle 1960s ( revised in 1980 ) . The Trewartha system sought to create a more refined middle latitude climate zone , which was one of the criticisms of the Köppen system ( the C climate group was too broad ) .

In planetary science , the Kombayashi -- Ingersoll limit represents the maximum solar flux a planet can handle without a runaway greenhouse effect setting in .   For planets with temperature-dependent sources of greenhouse gases such as liquid water and optically thin atmospheres the outgoing longwave radiation curve ( which indicates how fast energy can be radiated away by the planet ) flattens at high temperatures , reaching a horizontal asymptote -- the Kombayashi -- Ingersoll limit itself . Since the equilibrium temperature is the intersection of this curve and a horizontal line representing solar flux , for fluxes above this point the planet heats up indefinitely . Kasting estimated the limit for Earth to be 320 watts per square meter .   The limit is relevant for estimating the inner edge of the circumstellar habitable zone . However , the limit also depends on the surface gravity of the planet , making heavy worlds somewhat more resistant to the runaway effect .

In geology , solid-state recrystallization is a metamorphic process that occurs under temperature and pressure where atoms of a mineral are reorganized by diffusion and/or dislocation glide . The mineral composition may remain unchanged . This process can be illustrated by observing how snow recrystallizes to ice .   As opposed to metasomatism , which is a change in composition , recrystallization can be a purely physical process .   Limestone is a sedimentary rock that undergoes metamorphic recrystallization to form marble , and clays can recrystallize to muscovite mica .

Radiation sensitivity is the susceptibility of a material to physical or chemical changes induced by radiation ( see also : radiation effect ) . Examples of radiation sensitive materials are silver chloride , photoresists and biomaterials . Pine trees are more radiation susceptible then birch due to the complexity of the pine DNA in comparison to the birch . Examples of radiation insensitive materials are metals and ionic crystals such as quartz and sapphire . The radiation effect depends on the type of the irradiating particles , their energy and the number of incident particles per unit volume . Radiation effects can be transient or permanent . The persistence of the radiation effect depends on the stability of the induced physical and chemical change . Physical radiation effects depending on diffusion properties can be thermally annealed whereby the original structure of the material is recovered . Chemical radiation effects usually can not be recovered .


Question: Over time, decreased solar radiation reflected by Earth's surface as indicated by changes in albedo has led to an overall cooling effect on our planet’s climate system. This suggests that despite short-term fluctuations caused mainly through greenhouse gas emissions or volcanic eruptions which can temporarily increase temperature levels globally; there exists evidence pointing towards natural processes responsible for maintaining balance within ecosystems over longer periods without human intervention being necessary at all timescales considered thus far scientifically speaking anyway! However one must remain cautious when interpreting such data since other factors may also play significant roles depending upon specific circumstances encountered during any given period under investigation hereafter referred simply 'the study'. In conclusion then it appears reasonable enough prima facie case could potentially made supporting idea lower average annual air/water temps observed today compared yesterday might actually result indirectly anthropogenic activities afterall...or maybe not? Who knows really until further research conducted conclusively either way eh folks?!

 Cooling Trend Linked to Increased Planetary Reflectivity
The phenomenon known as "albedo," derived from the Latin word meaning "whiteness" and akin to Arabicalbayad, quantifies how much sunlight bounces off rather than being absorbed by terrestrial surfaces. Ranging from absolute zero (indicative of perfect absorption) up through unity (representing total reflection), this metric plays pivotal roles within diverse scientific disciplines spanning climatological studies, astronomical observations, alongside eco-friendly architectural designs certified under green building standards like LEED.
Planetary albedos fluctuate significantly depending upon prevailing meteorological conditions; notably clouds amplify overall values hovering around thirty percent globally yet stark contrasts emerge when focusing down onto particular locales influenced heavily by underlying geology plus ecological attributes alike. For instance: dense forests exhibit lower readings compared against snowy terrains where virtually every photon gets deflected back into space without imparting any thermal energy gain whatsoever!
Astronomers employ sophisticated instruments capable measuring minute variations emanating outwardly from distant celestial bodies while earthbound researchers prefer utilizing simpler methods involving ground-based sensors positioned strategically atop strategic locations designed monitoring fluctuations occurring seasonally throughout yearlong cycles respectively. Regardless methodology employed however, consensus remains firm regarding critical importance accorded understanding complex interplay existing amongst various components comprising intricate web constituting modern day ecosystems – especially pertinent considering looming specter posed anthropogenic induced climate disruptions threatening delicate balance maintained hitherto since dawn ages!

In essence then, higher degrees of reflectiveness correlate strongly negative feedback loops serving counteract potentially catastrophic runaway heating scenarios envisaged many doomsday prophets peddling apocalyptic visions lately... Instead what we observe empirically speaking seems suggest opposite trajectory altogether whereby enhanced luminosity stemming increased particulate matter suspended atmospherically acts brake slowing pace otherwise inexorable march toward universal thermodynamic equilibrium!

Rainwater harvesting is the accumulation and deposition of rainwater for reuse on-site , rather than allowing it to run off . Rainwater can be collected from rivers or roofs , and in many places the water collected is redirected to a deep pit ( well , shaft , or borehole ) , a reservoir with percolation , or collected from dew or fog with nets or other tools . Its uses include water for gardens , livestock , irrigation , domestic use with proper treatment , and indoor heating for houses etc. . The harvested water can also be used as drinking water , longer-term storage and for other purposes such as groundwater recharge .   Rainwater harvesting is one of the simplest and oldest methods of self-supply of water for households usually financed by the user .

LUCID ( Langton Ultimate Cosmic ray Intensity Detector ) is a cosmic ray detector built by Surrey Satellite Technology Ltd and designed at Simon Langton Grammar School for Boys , in Canterbury , England . Its main purpose is to monitor cosmic rays using technology developed by CERN , and will help predict the occurrence of solar flares ( proton storms ) which disrupt artificial satellites . LUCID was launched on 8 July 2014 at Baikonur , Kazakhstan as an instrument of the satellite TechDemoSat-1 , which was carried into space by a Soyuz-2 rocket .   Professor Larry Pinsky , Chair of Physics at the University of Houston , described the project in Symmetry Magazine as `` like playing at being NASA or the European Space Agency , but they 're not really playing . They 're doing the real thing . ''   Channel 4 News said of the LUCID project that `` with this metal box , the school has outwitted NASA '' .

Lanthanide contraction is a term used in chemistry to describe the greater-than-expected decrease in ionic radii of the elements in the lanthanide series from atomic number 57 , lanthanum , to 71 , lutetium , which results in smaller than otherwise expected ionic radii for the subsequent elements starting with 72 , hafnium . The term was coined by the Norwegian geochemist Victor Goldschmidt in his series `` Geochemische Verteilungsgesetze der Elemente '' .

In geology , lake capture is the process of capture ( see Stream capture ) of the waters collected in a lake by a neighbor river basin .   The occurrence of a lake capture is mainly controlled by the water balance at the lake 's basin and the changes in topography due to erosion , sedimentation , and tectonism . If evaporation at the surface of a lake , plus the water losses through underground infiltration and plant evapotranspiration are high enough to account for all precipitation water collected by the lake , then the lake becomes endorheic , closed , or internally drained . This situation prevails until the water balance changes again and the lake overburdens the limits of its basin or until the lake capture occurs . Opening the drainage of an endorheic lacustrine basin by fluvial erosion generally implies a lake capture .   Lake captures are therefore very sensitive to the preexisting topography as well as to climatic and lithological factors . A climatic change towards more humid conditions can result in a higher water level in the internally drained basin , eventually causing overflow , this . In a longer time-scale , sediment colmatation of the lacustrine basin can also lead to overflow . Both can hinder the relative importance of the capture process carried out by erosion .   Examples include the Late Neogen capture of the endorheic Ebro Basin ( capture ) or the Pleistocene Lake Bonneville .

The Langston Field is a fictional force field-like device featured in the CoDominium series of science-fiction novels , initiated by SF writer Jerry Pournelle .   The ( fictional ) Langston Field generator creates a spherical energy shield around an object ( usually a spacecraft , but cities have been known to deploy them ) which absorbs energy . Since the shield absorbs all wavelengths of light , it is completely black in normal use , like a black hole . It is necessary to raise a physical sensor device through the Field to see anything , much like a periscope . These sensors can be destroyed since they are outside the Field , so there are usually many backups on a warship . As the Field absorbs energy , it also radiates it over its entire surface , acting as a perfect black body ; the colour of the Field moves from infrared to red and through the visible spectrum to blue as the amount of reradiated energy increases . ( However , in The Mote in God 's Eye the field is also described as glowing green or violet , which is not possible for a true black body . It has been suggested that the Langston Field 's behavior is a tribute to the ray screens featured in Doc Smith 's novel The Skylark of Space , whose color also climbs the spectrum as the energy load increases . ) After a certain point , the Field generator can no longer absorb further energy : the Field collapses and the stored energy is released outwards and inwards ; the latter usually destroys the ship .

Laki or Lakagígar ( Craters of Laki ) is a volcanic fissure in the south of Iceland , not far from the canyon of Eldgjá and the small village of Kirkjubæjarklaustur . Lakagígar is the correct name , as Laki mountain itself did not erupt , as fissures opened up on each side of it . Lakagígar is part of a volcanic system centered on the volcano Grímsvötn and including the volcano Thordarhyrna . It lies between the glaciers of Mýrdalsjökull and Vatnajökull , in an area of fissures that run in a southwest to northeast direction .   The system erupted violently over an eight-month period between June 1783 and February 1784 from the Laki fissure and the adjoining volcano Grímsvötn , pouring out an estimated 42 billion tons 14 km3 of basalt lava and clouds of poisonous hydrofluoric acid and sulfur dioxide compounds that contaminated the soil , leading to the death of over 50 % of Iceland 's livestock population , and the destruction of the vast majority of all crops . This led to a famine which then killed approximately 25 % of the island 's human population . The lava flows also destroyed 20 villages .   The Laki eruption and its aftermath caused a drop in global temperatures , as 120 million tons of sulfur dioxide was spewed into the Northern Hemisphere . This caused crop failures in Europe and may have caused droughts in North Africa and India .

Radiance is a radiometric measure of the amount of light in an area .   Radiance may also refer to :

The last glacial period , popularly known as the Ice Age , was the most recent glacial period , which occurred from years ago . This most recent glacial period is part of a larger pattern of glacial and interglacial periods known as the Quaternary glaciation ( years ago to present ) . From this point of view , scientists consider this `` ice age '' to be merely the latest glaciation event in a much larger ice age , one that dates back over two million years and is still ongoing .   During this last glacial period , there were several changes between glacier advance and retreat . The Last Glacial Maximum , the maximum extent of glaciation within the last glacial period , was approximately 22,000 years ago . While the general pattern of global cooling and glacier advance was similar , local differences in the development of glacier advance and retreat make it difficult to compare the details from continent to continent ( see picture of ice core data below for differences ) . Approximately 13,000 years ago , the Late Glacial Maximum began . Around 11,700 years ago marked the beginning of the Holocene geological epoch , which includes the Holocene glacial retreat .   From the point of view of human archaeology , it falls in the Paleolithic and Mesolithic periods . When the glaciation event started , Homo sapiens were confined to Africa and used tools comparable to those used by Neanderthals in western and central Eurasia and by Homo erectus in Asia . Near the end of the event , Homo sapiens spread into Eurasia and Australia . Archaeological and genetic data suggest that the source populations of Paleolithic humans survived the last glacial period in sparsely wooded areas and dispersed through areas of high primary productivity while avoiding dense forest cover . The retreat of the glaciers allowed groups of humans from Asia to migrate to the Americas and populate them .

Radiation resistance is that part of an antenna 's feedpoint resistance that is caused by the radiation of electromagnetic waves from the antenna , as opposed to loss resistance ( also called ohmic resistance ) which generally causes the antenna to heat up . The total of radiation resistance and loss resistance is the electrical resistance of the antenna .   The radiation resistance is determined by the geometry of the antenna , where loss resistance is primarily determined by the materials of which it is made . While the energy lost by ohmic resistance is converted to heat , the energy lost by radiation resistance is converted to electromagnetic radiation .   Radiation resistance is caused by the radiation reaction of the conduction electrons in the antenna .   When electrons are accelerated , as occurs when an AC electrical field is impressed on an antenna , they will radiate electromagnetic waves . These waves carry energy that is taken from the electrons . Install The loss of energy of the electrons appears as an effective resistance to the movement of the electrons , analogous to the ohmic resistance caused by scattering of the electrons in the crystal lattice of the metallic conductor .   Power is calculated as   where is the electric current flowing into the feeds of the antenna and is the power in the resulting electromagnetic field . The result is a virtual , effective resistance :    This effective resistance is called the radiation resistance .

Laser ablation is the process of removing material from a solid ( or occasionally liquid ) surface by irradiating it with a laser beam . At low laser flux , the material is heated by the absorbed laser energy and evaporates or sublimates . At high laser flux , the material is typically converted to a plasma . Usually , laser ablation refers to removing material with a pulsed laser , but it is possible to ablate material with a continuous wave laser beam if the laser intensity is high enough .


Question:
 In recent times, we have observed an increase in the Earth's reflectivity or albedo; however, historical reconstructions reveal that prior to this trend, there was indeed a notable decline culminating around the year 1997 which coincided with a period of reduced solar activity known as 'the lull'."
This statement maintains the original sentence structure while changing some terms for variety: replacing "rose" with "increase," specifying what "reconstructions of the past albedo" entail (historical), and providing context about when exactly the decrease occurred ("prior to") along with additional information regarding potential causes ('coinciding'). It also keeps intact key phrases like "past few years" and "significant reduction". The overall meaning remains unchanged - highlighting changes over time concerning earths reflective properties- but presented differently enough so not sound repetitive if used multiple times within one piece without losing clarity on topic being discussed i.e., climate change effects specifically focusing here upon how much sunlight gets reflected back into space versus absorbed by our planet depending various factors including cloud cover & ice caps melting etc...).

 Recent Trends in Earth's Reflectivity
In recent studies, scientists observed fluctuations in Earth's reflectivity - known scientifically as its albedo. Over the last few decades, data suggests a notable decrease in Earth's ability to reflect sunlight back into space prior to stabilizing around 1997. This phenomenon contributes significantly to understanding how changes in atmospheric conditions can impact planetary temperatures. Historically, variations in Earth's albedo correlate closely with shifts during major climate events; notably, lower albedos coincide with warmer climates while higher values align more often than not with colder epochs akin to what occurs within extended glacial cycles spanning millions upon thousands if not billions depending upon your perspective but let us focus here specifically regarding those occurring since approximately two point six mya when large expanses formed across multiple continents thereby initiating what some refer simply nowdays without much thought given beforehand about whether they actually mean something else entirely different altogether instead just saying hey look another damn glacier coming right down Main Street again so maybe better use umbrella today huh?

Remote Skylights are optical systems capable of providing natural light to unlit locations . An arrangement of parabolic reflectors and optical fiber cables , transport natural sunlight to areas that would otherwise be dark or be lit artificially .   Remote skylights are composed chiefly of a solar collection dish , a `` heliotube '' and a distribution dish . The collection and distribution dishes are both parabolic reflectors . The collection dish is connected to a mechanism which tracks the transit of the sun across the sky , so as to maximise the intensity of light falling upon it . The heliotube is a bundle of optical fibres that channel the collected sunlight from the collection dish to the distribution dish . Unlike a typical skylight , the heliotube means that the two dishes do not need to be adjacent to one another .

Dew is water in the form of droplets that appears on thin , exposed objects in the morning or evening due to condensation . As the exposed surface cools by radiating its heat , atmospheric moisture condenses at a rate greater than that at which it can evaporate , resulting in the formation of water droplets .   When temperatures are low enough , dew takes the form of ice ; this form is called frost .   Because dew is related to the temperature of surfaces , in late summer it forms most easily on surfaces that are not warmed by conducted heat from deep ground , such as grass , leaves , railings , car roofs , and bridges .   Dew should not be confused with guttation , which is the process by which plants release excess water from the tips of their leaves .

In astronomy , a regular moon is a natural satellite following a relatively close and prograde orbit with little orbital inclination or eccentricity . They are believed to have formed in orbit about their primary , as opposed to irregular moons , which were captured .   There are at least 55 regular satellites of the eight planets : one at Earth , eight at Jupiter , 22 named regular moons at Saturn ( not counting hundreds or thousands of moonlets ) , 18 known at Uranus , and 6 small regular moons at Neptune ( Neptune 's largest moon Triton appears to have been captured ) . It is thought that Pluto 's five moons and Haumea 's two were formed in orbit about those dwarf planets out of debris created in giant collisions .

LHS 1140 is a red dwarf in the constellation of Cetus . Based on its stellar properties , it is thought to be about 41 light-years away from the Sun . ` LHS ' refers to the Luyten Half-Second Catalogue of stars with proper motions exceeding half a second of arc annually . The star is over 5 billion years old and has 15 % of the mass of the Sun . LHS 1140 's rotational period is 130 days . No flares have been observed .   LHS 1140 has a rocky planet , LHS 1140b , orbiting it . The planet is a super-Earth in a habitable zone and transits the star . This allows its atmosphere to be studied . The mass of LHS 1140b is 6.7 ± 1.8 times Earth 's and its radius is 1.4 ± 0.1 times as large , giving it a density roughly 2.3 ± 0.6 times that of Earth .   The orbit of LHS 1140b is nearly circular with a radius of 0.09 AU . LHS 1140b orbits and transits the star every 25 days . The planet was discovered by the MEarth Project . Radial velocities were measured by High Accuracy Radial Velocity Planet Searcher .

A reference work is a book or periodical ( or its electronic equivalent ) to which one can refer for information . The information is intended to be found quickly when needed . Reference works are usually referred to for particular pieces of information , rather than read beginning to end . The writing style used in these works is informative ; the authors avoid use of the first person , and emphasize facts . Many reference works are compiled by a team of contributors whose work is coordinated by one or more editors rather than by an individual author . Indices are commonly provided in many types of reference work . Updated editions are usually published as needed , in some cases annually ( e.g. Whitaker 's Almanack , Who 's Who ) . Reference works include dictionaries , thesauruses , encyclopedias , almanacs , bibliographies , and catalogs ( e.g. catalogs of libraries , museums or the works of individual artists ) . Many reference works are available in electronic form and can be obtained as application software , CD-ROMs , DVDs , or online through the Internet .   A reference work is useful to its users if they attribute some degree of trust .

The dipole model of the Earth 's magnetic field is a first order approximation of the rather complex true Earth 's magnetic field . Due to effects of the interplanetary magnetic field , and the solar wind , the dipole model is particularly inaccurate at high L-shells ( e.g. , above L = 3 ) , but may be a good approximation for lower L-shells . For more precise work , or for any work at higher L-shells , a more accurate model that incorporates solar effects , such as the Tsyganenko magnetic field model , is recommended .

The Shroud of Turin ( Turin Shroud ) , a linen cloth that tradition associates with the crucifixion and burial of Jesus , has undergone numerous scientific tests , the most notable of which is radiocarbon dating , in an attempt to determine the relic 's authenticity . In 1988 , scientists at three separate laboratories dated samples from the Shroud to a range of AD 1260 -- 1390 , which coincides with the first certain appearance of the shroud in the 1350s and is much later than the burial of Jesus . Aspects of the 1988 test continue to be debated . Despite some technical concerns that have been raised about radiocarbon dating of the Shroud , most experts assert that it is reliable .

The ΛCDM ( Lambda cold dark matter ) or Lambda-CDM model is a parametrization of the Big Bang cosmological model in which the universe contains a cosmological constant , denoted by Lambda ( Greek Λ ) , associated with dark energy , and cold dark matter ( abbreviated CDM ) . It is frequently referred to as the standard model of Big Bang cosmology because it is the simplest model that provides a reasonably good account of the following properties of the cosmos :  the existence and structure of the cosmic microwave background  the large-scale structure in the distribution of galaxies  the abundances of hydrogen ( including deuterium ) , helium , and lithium  the accelerating expansion of the universe observed in the light from distant galaxies and supernovae   The model assumes that general relativity is the correct theory of gravity on cosmological scales .  It emerged in the late 1990s as a concordance cosmology , after a period of time when disparate observed properties of the universe appeared mutually inconsistent , and there was no consensus on the makeup of the energy density of the universe .   The ΛCDM model can be extended by adding cosmological inflation , quintessence and other elements that are current areas of speculation and research in cosmology .   Some alternative models challenge the assumptions of the ΛCDM model . Examples of these are modified Newtonian dynamics , modified gravity and theories of large-scale variations in the matter density of the universe .

Decline involves change over time , for example :   from previously efficient to inefficient organizational functioning  from previously rational to non-rational organizational and individual decision-making  from previously law-abiding to law-violating organizational and individual behavior  from previously virtuous to iniquitous individual moral behavior   Note : distinguish the noun decline from the adjective obsolete . Decline refers to the degenerating of something ( compare obsolescence ) whereas obsolete refers to the outdatedness of something or labels something as no longer in use . Decline represents the process of declining , a gradual sinking and wasting away .   Social decline or moral decline is typically characterised as reduced adherence to cultural or social norms or values and widespread lapses in ethical behavior . Compare social decay .


Question: In recent times, there's been an observed increase in Earth’s reflectivity or albedo; however, historical data suggests that prior to this rise, we experienced substantial decrease in earth's reflective capacity culminating into a plateau around late nineties specifically year nineteen ninety seven. This implies potential fluctuations within our planet's natural cooling mechanisms over decades-long scales which could impact climate models predictions accuracy going forward depending on how well they account for such variability when projecting future scenarios under different greenhouse gas emission pathways (RCPs).

 Changes in Earth's Reflectivity: A Key Indicator of Climate Sensitivity
The reflectivity of Earth, known scientifically as its albedo, plays a crucial role in regulating planetary temperatures through interactions with sunlight. Recent studies indicate fluctuations in Earth's albedo; notably, after experiencing reduced reflectivity preceding a notable dip around 1997, recent trends suggest an upward trend in Earth's albedo. These shifts highlight complex dynamics within the climate system influenced by various factors.
Understanding how sensitive climates respond to external forcings - particularly those related to greenhouse gases – is pivotal for predicting future conditions. Climate sensitivity quantifies expected temperature alterations resulting directly from perturbations in radiative balance, typically measured using degrees Celsius per watt per square meter (∆T/RF). Notably, while initially focused on responses triggered exclusively by increases in atmospheric concentrations of carbon dioxide(CO2), research now acknowledges comparable effects arising independently across diverse sources impacting radiation budgets globally.
Incorporating slow-acting mechanisms into assessments reveals additional amplification pathways beyond immediate thermal adjustments alone. Factors encompassing modifications to continental ice sheets alongside variations in atmospheric composition emerge critical determinants shaping overall earth-system sensitivities when considering longer temporal scales. However, pinpointing exact magnitudes remains challenging given inherent complexities involved.
For comprehensive climate simulations utilizing advanced modeling frameworks (e.g., Coupled Model Intercomparison Project Phase Five [CMIP5]), climate sensitivity emerges organically without direct specification—resultant instead from intricate interplay among underlying physical principles governing modeled environments. Conversely, simplified analytical approaches frequently incorporate climate sensitivity explicitly as adjustable variables subject to optimization procedures during calibration phases.
Key relationships encapsulated mathematically link radiative forcing metrics against corresponding global mean surface temperature deviations ∆Ts through scaling factor λ representing effective climate responsiveness under varying scenarios. Leveraging historical records offers tantalizing prospects for empirical validation albeit fraught with caveats stemming predominantly from imperfect knowledge regarding both forcings history itself plus intrinsic variability embedded throughout geophysical systems being studied.

Recely Bluff is a snow and rock bluff on the northeast slope of Mount Siple on Siple Island . The bluff is 7 nautical miles ( 13 km ) northeast of the summit of the mountain . It is mapped by United States Geological Survey ( USGS ) from surveys and U.S. Navy aerial photography , 1959 -- 65 . It was named by Advisory Committee on Antarctic Names ( US-ACAN ) for Frank J. Recely , Jr. , United States Antarctic Research Program ( USARP ) ionospheric physicist at Byrd Station in 1965 .    Category : Cliffs of Marie Byrd Land

In ecology , rarefaction is a technique to assess species richness from the results of sampling . Rarefaction allows the calculation of species richness for a given number of individual samples , based on the construction of so-called rarefaction curves . This curve is a plot of the number of species as a function of the number of samples . On the left , the steep slope indicates that a large fraction of the species diversity remains to be discovered . If the curve becomes flatter to the right , a reasonable number of individual samples have been taken : more intensive sampling is likely to yield only few additional species .   The issue that occurs when sampling various species in a community is that the larger the number of individuals sampled , the more species that will be found . Rarefaction curves are created by randomly re-sampling the pool of N samples multiple times and then plotting the average number of species found in each sample ( 1,2 , ... N ) . `` Thus rarefaction generates the expected number of species in a small collection of n individuals ( or n samples ) drawn at random from the large pool of N samples . '' . Rarefaction curves generally grow rapidly at first , as the most common species are found , but the curves plateau as only the rarest species remain to be sampled .

The 1950s ( pronounced nineteen-fifties ; commonly abbreviated as the 50s or Fifties ) was a decade of the Gregorian calendar that began on January 1 , 1950 , and ended on December 31 , 1959 .   By its end , the world had largely recovered from World War II and the Cold War developed from its modest beginning in the late-1940s to a hot competition between the United States and the Soviet Union by the early-1960s .   Clashes between communism and capitalism dominated the decade , especially in the Northern Hemisphere . The conflicts included the Korean War in the beginnings of the decade and the beginning of the Space Race with the launch of Sputnik 1 . Along with increased testing of nuclear weapons ( such as RDS-37 and Upshot -- Knothole ) , this created a politically conservative climate . In the United States , the Second Red Scare caused Congressional hearings by both houses in Congress and anti-communism was the prevailing sentiment in the United States throughout the decade . The beginning of decolonization in Africa and Asia took place in this decade and accelerated in the following decade .

Recession shapes are used by economists to describe different types of recessions . There is no specific academic theory or classification system for recession shapes ; rather the terminology is used as an informal shorthand to characterize recessions and their recoveries .   The most commonly used terms are V-shaped , U-shaped , W-shaped , and L-shaped recessions . The shapes take their names from the approximate shape economic data make in graphs during recessions . The letters can also be applied referring to the recoveries ( ie `` V-shaped recovery '' ) .

Recalescence is an increase in temperature that occurs while cooling metal when a change in structure with an increase in entropy occurs . The heat responsible for the change in temperature is due to the change in entropy . When a structure transformation occurs the Gibbs free energy of both structures are more or less the same . Therefore the process will be exothermic . The heat provided is the latent heat .   Recalescence also occurs after supercooling , when the supercooled liquid suddenly crystallizes , forming a solid but releasing heat in the process .

ROYGBIV or Roy G. Biv is an acronym for the sequence of hues commonly described as making up a rainbow : red , orange , yellow , green , blue , indigo and violet .   A rainbow spans a continuous spectrum of colors ; the distinct bands are an artifact of human color vision . In ROYGBIV , the colors are arranged in the order of decreasing wavelengths , with red being 650 nm and violet being about 400 nm . The acronym is memorable because Roy is a common male given name , so Roy G. Biv sounds like a first name , middle initial , and a last name .

In statistics , a receiver operating characteristic curve , i.e. ROC curve , is a graphical plot that illustrates the diagnostic ability of a binary classifier system as its discrimination threshold is varied .   The ROC curve is created by plotting the true positive rate ( TPR ) against the false positive rate ( FPR ) at various threshold settings . The true-positive rate is also known as sensitivity , recall or probability of detection in machine learning . The false-positive rate is also known as the fall-out or probability of false alarm and can be calculated as ( 1 − specificity ) . The ROC curve is thus the sensitivity as a function of fall-out . In general , if the probability distributions for both detection and false alarm are known , the ROC curve can be generated by plotting the cumulative distribution function ( area under the probability distribution from to the discrimination threshold ) of the detection probability in the y-axis versus the cumulative distribution function of the false-alarm probability on the x-axis .   ROC analysis provides tools to select possibly optimal models and to discard suboptimal ones independently from ( and prior to specifying ) the cost context or the class distribution . ROC analysis is related in a direct and natural way to cost/benefit analysis of diagnostic decision making .   The ROC curve was first developed by electrical engineers and radar engineers during World War II for detecting enemy objects in battlefields and was soon introduced to psychology to account for perceptual detection of stimuli . ROC analysis since then has been used in medicine , radiology , biometrics , and other areas for many decades and is increasingly used in machine learning and data mining research .   The ROC is also known as a relative operating characteristic curve , because it is a comparison of two operating characteristics ( TPR and FPR ) as the criterion changes .

A reflector sight or reflex sight is an optical device that allows the user to look through a partially reflecting glass element and see an illuminated projection of an aiming point or some other image superimposed on the field of view . These sights work on the simple optical principle that anything at the focus of a lens or curved mirror ( such as an illuminated reticle ) will look like it is sitting in front of the viewer at infinity . Reflector sights employ some sort of `` reflector '' to allow the viewer to see the infinity image and the field of view at the same time , either by bouncing the image created by lens off a slanted glass plate , or by using a mostly clear curved glass reflector that images the reticle while the viewer looks through the reflector . Since the reticle is at infinity it stays in alignment with the device the sight is attached to regardless of the viewer 's eye position , removing most of the parallax and other sighting errors found in simple sighting devices .   Since their invention in 1900 , reflector sights have come to be used as gun sights on all kinds of weapons . They were used on fighter aircraft , in a limited capacity in World War I , widely used in World War II , and still used as the base component in many types of modern head-up displays . They have been used in other types of ( usually large ) weapons as well , such as anti-aircraft gun sights , anti tank gun sights , and any other role where the operator had to engage fast moving targets over a wide field of view , and the sight itself could be supplied with sufficient electrical power to function . There was some limited use of the sight on small arms after World War II but it came into widespread use after the late 1970s with the invention of the red dot sight , with a red light-emitting diode ( LED ) as its reticle , making a dependable sight with durability and extremely long illumination run time .   Reflector sights are also used in civilian applications such as sights on surveying equipment , optical telescope pointing aids , and camera viewfinders .

In biology , the range or distribution of a species is the geographical area within which that species can be found . Within that range , dispersion is variation in local density .   The term is often qualified :   Sometimes a distinction is made between a species ' natural , endemic , or native range where it historically originated and lived , and the range where a species has more recently established itself . Many terms are used to describe the new range , such as non-native , naturalized , introduced , transplanted , invasive , or colonized range . Introduced typically means that a species has been transported by humans ( intentionally or accidentally ) across a major geographical barrier .  For species found in different regions at different times of year , terms such as summer range and winter range are often employed .  For species for which only part of their range is used for breeding activity , the terms breeding range and non-breeding range are used .  For mobile animals , the term natural range is often used , as opposed to areas where it occurs as a vagrant .  Geographic or temporal qualifiers are often added : for example , British range or pre-1950 range .   There are at least five types of distribution patterns :   Scattered/random ( Random placement )  Clustered/grouped ( Most are placed in one area )  Linear ( Their placements form a line )  Radial ( Placements form an ' x ' shape )  Regular/ordered ( They are not random at all , but follow a set placement . Much like a grid )

The 1257 Samalas eruption was a major volcanic eruption of the Samalas volcano , next to Mount Rinjani on the island of Lombok , Indonesia . It left a large caldera next to Rinjani volcano , the lake Segara Anak . This volcanic eruption reached a volcanic explosivity index of 7 , making it one of the largest eruptions of the Holocene . The occurrence of this eruption was originally deduced from ice core information revealing a spike in sulfate deposition around the year 1257 ; in 2013 the source of this eruption at Samalas was definitively proven as a result of historical records from that time .   This eruption proceeded during four distinct phases , alternately creating eruption columns reaching up for tens of kilometres and pyroclastic flows that buried large parts of Lombok , destroying human habitations including the city of Pamatan . Ash from the eruption fell as far as Java . The volume of the deposits left exceeds 10 km3 . Later activity from the volcano created additional volcanic centres in the caldera , including the present day active Barujari cone .   The eruption was witnessed by humans on Lombok , who recorded its effects on text written on palm leaves . The aerosols injected by the volcano into the atmosphere reduced the solar radiation reaching the surface of the Earth , triggering a volcanic winter and cooling lasting for several years . It is possible that the 1257 Samalas eruption helped trigger the Little Ice Age .
