Question:
 The 'clean coal' technique involves capturing carbon dioxide produced by burning fossil fuels at power stations and storing it deep beneath the earth's surface. This method aims to reduce greenhouse gas emissions while continuing to utilize coal as an energy source. However, critics argue that this technology may not be economically viable or effective enough to significantly mitigate climate change impacts associated with continued reliance on coal for electricity generation purposes globally speaking over time periods relevant both locally regionally internationally respectively so there needs more research done before we can say anything definitive about how well these systems will work when scaled up beyond pilot projects currently underway around world today including but not limited too USA China India Australia Germany Poland South Africa Indonesia Turkey etcetera ad nauseam until kingdom come amen hallelujah pass me another beer please thank you very much goodnight everybody!

 Clean Coal Technologies: A Closer Look
The concept known publicly as 'clean coal' encompasses several strategies aimed at minimizing pollutants typically linked to coal usage during industrial applications and electricity generation - particularly focusing on mitigating its notorious status as the least environmentally friendly among conventional energy sources. Critics argue that labeling any form of coal utilization as "clean" borders on linguistic manipulation akin to George Orwell’s dystopian language control tactics; yet proponents insist there exist viable methods capable of significantly curtailing harmful outputs without sacrificing economic benefits derived from abundant reserves.

Efforts concentrate predominantly upon curbing release quantities of Carbon Dioxide (CO₂), alongside additional Greenhouse Gases & Radioactive Substances generated through coal exploitation – chiefly targeting Electricity Production Sector innovations. Historically speaking, initial endeavors commenced circa mid-19th century via Flue-Gas Desulphurisation techniques coupled with Enhanced Combustion Efficiency measures designed specifically against Sulphur Oxide discharges. Modern advancements highlight two key methodologies:

Carbon Capture Storage (CCS) entails trapping emitted CO₂ post-combustion phase followed by secure subterranean injection;
Integrated Gasification Combined Cycle Systems (IGCC) employ advanced Gasification Processes enabling superior performance metrics when sequestering CO₂ effluents.
Seven prominent approaches either implemented domestically within America or undergoing developmental stages encompass:
CCS Deployment,
Flue-Gas Desulphurisation Upgrades,
Fluidised Bed Combustors,
IGCC Installations,
Nitrogen Oxides Reduction Burner Designs,
Selective Catalytic Reactor Units,
Electrostatic Precipitation Equipment.
Despite US Governmental Financial Support spanning across multiple initiatives since early twenty-first century inception, actual operational instances remain elusive up until late winter season preceding current year timeline—project abandonment/delay attributed largely owing to escalating construction costs juxtaposed against prohibitive maintenance expenditure overheads.

Deep space exploration ( or deep-space exploration ) is the branch of astronomy , astronautics and space technology that is involved with exploring the distant regions of outer space . Physical exploration of space is conducted both by human spaceflights ( deep-space astronautics ) and by robotic spacecraft .   At present the furthest space probe mankind has constructed and launched from Earth is Voyager 1 , which was announced on December 5 , 2011 to have reached the outer edge of the Solar system , and entered interstellar space on August 25 , 2012 . Deep space exploration further than this vessel 's capacity is not yet possible due to limitations in the space-engine technology currently available .   Some of the best candidates for future deep space engine technologies include anti-matter , nuclear power and beamed propulsion . The latter , beamed propulsion , appears to be the best candidate for deep space exploration presently available , since it uses known physics and known technology that is being developed for other purposes .

Depression storage capacity , in soil science , is the ability of a particular area of land to retain water in its pits and depressions , thus preventing it from flowing . Depression storage capacity , along with infiltration capacity , is one of the main factors involved in Horton overland flow , whereby water volume surpasses both infiltration and depression storage capacity and begins to flow horizontally across land , possibly leading to flooding and soil erosion . The study of land 's depression storage capacity is important in the fields of geology , ecology , and especially hydrology .   Category : Hydrology  Category : Soil physics

Regulatory capture is a form of government failure that occurs when a regulatory agency , created to act in the public interest , instead advances the commercial or political concerns of special interest groups that dominate the industry or sector it is charged with regulating . When regulatory capture occurs , the interests of firms or political groups are prioritized over the interests of the public , leading to a net loss to society as a whole . Government agencies suffering regulatory capture are called `` captured agencies '' .

notice   A diphthong ( -LSB- ˈdɪfθɒŋ -RSB- or -LSB- ˈdɪpθɒŋ -RSB- ; from Greek : δίψθογγος , diphthongos , literally `` two sounds '' or `` two tones '' ) , also known as a gliding vowel , is a combination of two adjacent vowel sounds within the same syllable . Technically , a diphthong is a vowel with two different targets : that is , the tongue ( and/or other parts of the speech apparatus ) moves during the pronunciation of the vowel . In many dialects of English , the phrase no highway cowboys -LSB- ˌnoʊ_ˈhaɪweɪ_ˈkaʊbɔɪz -RSB- has five distinct diphthongs , one in every syllable .   Diphthongs contrast with monophthongs , where the tongue or other speech organs do not move and the syllable contains only a single vowel sound . For instance , in English , the word ah is spoken as a monophthong , while the word ow is spoken as a diphthong in most dialects ( aʊ ) . Where two adjacent vowel sounds occur in different syllables -- for example , in the English word re-elect -- the result is described as hiatus , not as a diphthong .   Diphthongs often form when separate vowels are run together in rapid speech during a conversation . However , there are also unitary diphthongs , as in the English examples above , which are heard by listeners as single-vowel sounds ( phonemes ) .   Diphthongs use two vowel sounds in one syllable to make a speech sound .

The Renewables Obligation ( RO ) is designed to encourage generation of electricity from eligible renewable sources in the United Kingdom . It was introduced in England and Wales and in a different form ( the Renewables Obligation ( Scotland ) ) in Scotland in April 2002 and in Northern Ireland in April 2005 , replacing the Non-Fossil Fuel Obligation which operated from 1990 .   The RO places an obligation on licensed electricity suppliers in the United Kingdom to source an increasing proportion of electricity from renewable sources , similar to a renewable portfolio standard . In 2010/11 it is 11.1 % ( 4.0 % in Northern Ireland ) . This figure was initially set at 3 % for the period 2002/03 and under current political commitments will rise to 15.4 % ( 6.3 % in Northern Ireland ) by the period 2015/16 and then it runs until 2037 ( 2033 in Northern Ireland ) . The extension of the scheme from 2027 to 2037 was declared on 1 April 2010 and is detailed in the National Renewable Energy Action Plan . Since its introduction the RO has more than tripled the level of eligible renewable electricity generation ( from 1.8 % of total UK supply to 7.0 % in 2010 ) .

Land , sometimes referred to as dry land , is the solid surface of Earth that is not permanently covered by water . The vast majority of human activity throughout history has occurred in land areas that support agriculture , habitat , and various natural resources . Some life forms ( including terrestrial plants and terrestrial animals ) have developed from predecessor species that lived in bodies of water .   Areas where land meets large bodies of water are called coastal zones . The division between land and water is a fundamental concept to humans . The demarcation between land and water can vary by local jurisdiction and other factors . A maritime boundary is one example of a political demarcation . A variety of natural boundaries exist to help clearly define where water meets land . Solid rock landforms are easier to demarcate than marshy or swampy boundaries , where there is no clear point at which the land ends and a body of water has begun . Demarcation can further vary due to tides and weather .

The Laurel Run mine fire is an underground mine fire near the communities of Laurel Run and Georgetown , in Luzerne County , Pennsylvania , in the United States . The fire started burning in 1915 at the Red Ash Coal Mine . Attempts to control it lasted from 1915 to 1957 and recommenced in 1966 . In the 1960s , the United States government and the Pennsylvania state government became involved in containing the fire . Attempts at stopping the spread of the fire were erroneously declared successful in 1973 , but the fire is still burning .

The United Nations Intergovernmental Panel on Climate Change ( IPCC ) published a special report on Renewable Energy Sources and Climate Change Mitigation ( SRREN ) on May 9 , 2011 . The report developed under the leadership of Ottmar Edenhofer evaluates the global potential for using renewable energy to mitigate climate change . This IPCC special report provides broader coverage of renewable energy than was included in the IPCC 's 2007 climate change assessment report , as well as stronger renewable energy policy coverage .   Renewable energy can contribute to `` social and economic development , energy access , secure energy supply , climate change mitigation , and the reduction of negative environmental and health impacts '' . Under favourable circumstances , cost savings in comparison to non-renewable energy use exist .

reCAPTCHA is a CAPTCHA-like system designed to establish that a computer user is human ( normally in order to protect websites from bots ) and , at the same time , assist in the digitization of books . reCAPTCHA was originally developed by Luis von Ahn , Ben Maurer , Colin McMillen , David Abraham and Manuel Blum at Carnegie Mellon University 's main Pittsburgh campus . It was acquired by Google in September 2009 .   reCAPTCHA has completed digitizing the archives of The New York Times and books from Google Books , as of 2011 . The archive can be searched from the New York Times Article Archive , where more than 13 million articles in total have been archived , dating from 1851 to the present day . Through mass collaboration , reCAPTCHA was helping to digitize books that are too illegible to be scanned by computers , as well as translate books to different languages , as of 2015 .   The system has been reported as displaying over 100 million CAPTCHAs every day , on sites such as Facebook , TicketMaster , Twitter , 4chan , CNN.com , StumbleUpon , Craigslist ( since June 2008 ) , and the U.S. National Telecommunications and Information Administration 's digital TV converter box coupon program website ( as part of the US DTV transition ) .   reCAPTCHA 's slogan was `` Stop Spam , Read Books . '' , until the introduction of a new version of the reCAPTCHA plugin in 2014 ; the slogan has now disappeared from the website and from the classic version of the reCAPTCHA plugin . A new system featuring image verification was also introduced . In this system , users are asked to just click on a checkbox ( the system will verify whether the user is a human or not , for example , with some clues such as already-known cookies or mouse movements within the ReCAPTCHA frame ) or , if it fails , select one or more images from a selection of nine images .

The Department of Climate Change and Energy Efficiency was an Australian Government department . Its role was to serve the people of Australia by developing a more prosperous and sustainable Australia by leading and coordinating the mitigation of greenhouse gas emissions , promotion of energy efficiency , adaptation to climate change and shaping of global solutions .   The Department was led by its Secretary , Blair Comley PSM who was responsible to the Minister for Climate Change and Energy Efficiency , the Honourable Greg Combet AM MP . The minister was assisted by the Parliamentary  Secretary for Climate Change and Energy Efficiency , the Honourable Mark Dreyfus QC MP .   On 25 March 2013 , responsibility for Climate Change passed to the newly formed Department of Industry , Innovation , Climate Change , Science , Research and Tertiary Education .


Question: Predictive climate models have exaggerated estimations of temperature increases associated with global warming.

 Reassessing Predictive Accuracy: Are Current Climate Models Too Pessimistic?
The reliability of predictive climate models has come under scrutiny recently, with some scientists arguing they might exaggerate projected increases in global temperatures. These complex simulations attempt to forecast changes in earth’s climate based on various scenarios involving greenhouse gases, solar radiation, oceanic heat absorption, among others. Critics suggest current models could underestimate cooling mechanisms within nature -like volcanic eruptions spewing sulfur particles into stratosphere- leading us astray when planning mitigation strategies against anthropogenic impacts. However, understanding uncertainties remains crucial; while adjustments seem necessary, dismissing decades’ worth research outright would ignore valuable insights gained thus far about interconnected planetary dynamics affecting all life forms inhabiting terrestrial ecosystems across continents & oceans alike! Moreover, even if revised predictions show less dire outcomes than initially thought possible just few years ago thanks partly due better integration artificial intelligence techniques helping refine algorithms behind calculations performed inside supercomputers running terabytes upon petabytes worth raw observational data collected globally every single day...we still face significant challenges ahead unless concerted international cooperation ensues soon enough tackling root causes behind accelerating pace observed during last half-century especially concerning CO2 levels emitted mostly via burning fossil fuels powering modern civilization's energy demands without proper regard paid beforehand ensuring sustainability going forward indefinitely instead relying heavily upon finite reserves destined run dry sooner rather later regardless what happens elsewhere politically speaking regarding treaties signed amongst nations trying curb emissions collectively yet failing miserably so far achieving desired reductions fast enough counteract ongoing damage done already irreversibly altering landscapes forevermore rendering many regions uninhabitable forcing mass migrations internally displacing millions overnight creating humanitarian crises unseen proportions dwarfing anything witnessed history books recounting tales civilizations past collapsing suddenly seemingly overnight reasons unknown until archaeologists pieced together clues left behind millennia afterwards uncovering shocking truths hidden away deep underground waiting patiently discovered eons henceforth revealing secrets locked tight vaults guarded zealously priests serving gods forgotten names whispered softly winds blowing gently through ruins once majestic palaces now reduced rubble scattered haphazardly around desolate wastelands devoid vegetation animal life save scavengers picking bones clean carcasses lying exposed baking sun merciless rays beating down relentlessly scorching skin turning flesh crispy blackened husks consumed entirely fire raging uncontrollably consuming everything path indiscriminately sparing nothing standing way unstoppable force unleashed unwittingly mankind tinkering casually doomsday devices never intended activated accidentally triggering chain reaction events spiraling wildly careening headlong abyss oblivion dragging entire world kicking screaming along ride doomed failure spectacular fashion reminiscent final scenes epic disaster movies Hollywood churned regularly entertaining audiences

A kludge ( or kluge ) ( / klʌdʒ / , / kluːʒ / , / kluːdʒ / ) is a workaround or quick-and-dirty solution that is clumsy , inelegant , inefficient , difficult to extend and hard to maintain . This term is used in diverse fields such as computer science , aerospace engineering , Internet slang , evolutionary neuroscience , and government .

David X. Li ( born in Nanjing , China , in the 1960s as ) is a quantitative analyst and a qualified actuary who in the early 2000s pioneered the use of Gaussian copula models for the pricing of collateralized debt obligations ( CDOs ) . The Financial Times called him `` the world 's most influential actuary '' , while in the aftermath of the global financial crisis of 2008 -- 2009 , to which Li 's model has been credited partly to blame , his model has been called a `` recipe for disaster '' .

Regulatory risk differentiation the process used by a regulatory authority ( the regulator ) to systemically treat entities differently based on the regulator 's assessment of the risks of the entity 's non-compliance .   Regulators can include law enforcement agencies , while the word entities applies to all those under the authority of the regulator -- in most cases ranging from individuals to companies to synthetic entities to multinationals operating within the regulator 's jurisdiction .   The process requires the regulator to directly link a robust risk assessment to a suggested regulatory response ( e.g. financial penalties , criminal imprisonment ) . Regulatory risk differentiation is also referred to as the Compliance Model in some regulatory agencies . See for example the Australian Prudential Regulatory Authority risk differentiation approach known as : PAIRS / SOARS . PAIRS is the Probability And Impact Rating System , while SOARS is the Supervisory Oversight And Response System .

The Kübler-Ross model , or the five stages of grief , postulates a series of emotions experienced by terminally ill patients prior to death , or people who have lost a loved one , wherein the five stages are denial , anger , bargaining , depression and acceptance .   The model was first introduced by Swiss psychiatrist Elisabeth Kübler-Ross in her 1969 book On Death and Dying , and was inspired by her work with terminally ill patients . Motivated by the lack of instruction in medical schools on the subject of death and dying , Kübler-Ross examined death and those faced with it at the University of Chicago medical school . Kübler-Ross ' project evolved into a series of seminars which , along with patient interviews and previous research , became the foundation for her book . Since the publication of On Death and Dying , the Kübler-Ross model has become accepted by the general public ; however , its validity is not consistently supported by the majority of research .   Kübler-Ross noted later in life that the stages are not a linear and predictable progression and that she regretted writing them in a way that was misunderstood . Rather , they are a collation of five common experiences for the bereaved that can occur in any order , if at all .

Reproducibility is the ability of an entire analysis of an experiment or study to be duplicated , either by the same researcher or by someone else working independently , whereas reproducing an experiment is called replicating it . Reproducibility and replicability together are among the main principles of the scientific method .   The values obtained from distinct experimental trials are said to be commensurate if they are obtained according to the same reproducible experimental description and procedure . The basic idea can be seen in Aristotle 's dictum that there is no scientific knowledge of the individual , where the word used for individual in Greek had the connotation of the idiosyncratic , or wholly isolated occurrence . Thus all knowledge , all science , necessarily involves the formation of general concepts and the invocation of their corresponding symbols in language ( cf. Turner ) . Aristotle ′ s conception about the knowledge of the individual being considered unscientific is due to lack of the field of statistics in his time , so he could not appeal to statistical averaging by the individual .   A particular experimentally obtained value is said to be reproducible if there is a high degree of agreement between measurements or observations conducted on replicate specimens in different locations by different people -- that is , if the experimental value is found to have a high precision . However , in science , a very well reproduced result is one that can be confirmed using as many different experimental setups as possible and as many lines of evidence as possible ( consilience ) .

Large numbers are numbers that are significantly larger than those ordinarily used in everyday life , for instance in simple counting or in monetary transactions . The term typically refers to large positive integers , or more generally , large positive real numbers , but it may also be used in other contexts .   Very large numbers often occur in fields such as mathematics , cosmology , cryptography , and statistical mechanics . Sometimes people refer to numbers as being `` astronomically large '' . However , it is easy to mathematically define numbers that are much larger even than those used in astronomy .

The real exchange-rate puzzles is a common term for two much-discussed anomalies of real exchange rates : that real exchange rates are more volatile and show more persistence than what most models can account for . These two anomalies are sometimes referred to as the purchasing power parity puzzles .   Dornbusch 's ( 1976 ) exchange rate overshooting hypothesis argued that exchange rate volatility is essentially driven by monetary shocks interacting with sticky prices . This model can account for real exchange rate volatility , but does not say anything about the volatility of relative to output or the persistence of the real exchange rate movements .   Chari , Kehoe and McGrattan ( 2002 ) showed how a model with two countries and where prices were only allowed to change once-a-year had the potential to simultaneously account for the volatility of U.S. output and real exchange rates .   These two anomalies are related to , but should not be confused with , the Backus-Smith consumption-real exchange rate anomaly , which is the observation that in most economic models the correlation between the real exchange rate and relative consumption is high and positive , whereas in the data it ranges from small and positive to negative .   Another real-exchange-rate anomaly was documented by Mussa ( 1986 ) . In this paper Mussa documented that industrial countries which moved from fixed to floating exchange rate regimes experienced dramatic rises in nominal-exchange-rate volatility . Since the volatility increases much more than what can be accounted for by changes in the domestic price levels , it means that the real-exchange-rate volatility increases . This is sometimes referred to as the `` Mussa puzzle '' .   Obstfeld and Rogoff ( 2000 ) identified the purchasing power and exchange rate disconnect puzzle as one of the six major puzzles in international economics . These were the consumption correlation puzzle , home bias in trade puzzle , the equity home bias puzzle , the Feldstein-Horioka savings-investment correlations puzzle , and the exchange rate regime puzzle . The sixth puzzle is described as `` why exchange rates are so volatile and apparently disconnected from fundamentals '' . Here Obstfeld and Rogoff ( 2000 ) quotes the Meese and Rogoff ( 1983 ) exchange rate forecasting puzzle and the Baxter and Stockman ( 1989 ) neutrality of exchange rate regime puzzle . These two puzzles are closely to the Mussa puzzle as well as the other real exchange rate puzzles .

In engineering , redundancy is the duplication of critical Components or functions of a system with the intention of increasing reliability of the system , usually in the form of a backup or fail-safe , or to improve actual system performance , such as in the case of GNSS receivers , or multi-threaded computer processing .   In many safety-critical systems , such as fly-by-wire and hydraulic systems in aircraft , some parts of the control system may be triplicated , which is formally termed triple modular redundancy ( TMR ) . An error in one component may then be out-voted by the other two . In a triply redundant system , the system has three sub components , all three of which must fail before the system fails . Since each one rarely fails , and the sub components are expected to fail independently , the probability of all three failing is calculated to be extraordinarily small ; often outweighed by other risk factors , such as human error . Redundancy may also be known by the terms `` majority voting systems '' or `` voting logic '' .   Redundancy sometimes produces less , instead of greater reliability it creates a more complex system which is prone to various issues , it may lead to human neglect of duty , and may lead to higher production demands which by overstressing the system may make it less safe .

A `` late model car '' is a car which has been recently designed or manufactured , often the latest model . ( An `` early model car '' or `` classic car '' is a car old enough to be of historical interest ; there is no usual intermediate term . ) The term is broadly used in car racing , and often appears in common use , as in : `` The officer was driving an unmarked , late model sedan . ''   The precise definition of `` late model '' varies .

In numerical analysis , Richardson extrapolation is a sequence acceleration method , used to improve the rate of convergence of a sequence . It is named after Lewis Fry Richardson , who introduced the technique in the early 20th century . In the words of Birkhoff and Rota , `` its usefulness for practical computations can hardly be overestimated . ''   Practical applications of Richardson extrapolation include Romberg integration , which applies Richardson extrapolation to the trapezoid rule , and the Bulirsch -- Stoer algorithm for solving ordinary differential equations .


Question: Predictive climate models have exaggerated estimations of temperature increases associated with global warming.

 Reevaluation of Global Warming Projections
Recent studies suggest that some climate models might have exaggerated predictions regarding global warming trends. These findings stem from refined methodologies and updated data sets that offer greater accuracy compared to earlier projections. Critics argue that initial assumptions concerning feedback mechanisms within earth systems were overly sensitive to CO2 increases, leading to overstated estimates of future temperatures rises. Notably, researchers now emphasize uncertainties surrounding cloud cover effects and oceanic heat absorption capacity - two critical variables influencing planetary warmth retention capabilities. Although anthropogenic impacts remain significant contributors to observed changes, recalibrated simulations indicate less severe outcomes under current emission scenarios than initially projected by influential modeling groups around the globe.

Decision tree learning uses a decision tree ( as a predictive model ) to go from observations about an item ( represented in the branches ) to conclusions about the item 's target value ( represented in the leaves ) . It is one of the predictive modelling approaches used in statistics , data mining and machine learning . Tree models where the target variable can take a finite set of values are called classification trees ; in these tree structures , leaves represent class labels and branches represent conjunctions of features that lead to those class labels . Decision trees where the target variable can take continuous values ( typically real numbers ) are called regression trees .   In decision analysis , a decision tree can be used to visually and explicitly represent decisions and decision making . In data mining , a decision tree describes data ( but the resulting classification tree can be an input for decision making ) . This page deals with decision trees in data mining .

Knowledge modeling is a process of creating a computer interpretable model of knowledge or standard specifications about a kind of process and/or about a kind of facility or product . The resulting knowledge model can only be computer interpretable when it is expressed in some knowledge representation language or data structure that enables the knowledge to be interpreted by software and to be stored in a database or data exchange file .  Knowledge-based engineering or knowledge-aided design is a process of computer-aided usage of such knowledge models for the design of products , facilities or processes . The design of products or facilities then uses the knowledge model to guide the creation of the facility or product that need to be designed . In other words , it used knowledge about a kind of object to create a product model of an ( imaginary ) individual object . Similarly , the design of a particular process implies the creation of a process model , which design activity can be guided by the knowledge that is contained in a knowledge model about such a kind of process . The resulting process model , product model or facility model is typically also stored in a database .   Usually the knowledge representation language only allows to represent knowledge ( about kinds of things ) , whereas another language or data structure is required to represent and store the information models about individual things . If the knowledge representation language enables to express both , then the knowledge model and the information model can be expressed in the same language ( or data structure ) . An example of a language that enables the expression of knowledge as well as information about individual things is Gellish English .   The basis of a knowledge model of an assembly physical object is a decomposition structure that specifies the components of the assembly and possible the sub-components of the components .  For example , knowledge about a compressor system includes that a compressor system consists of a compressor , a lubrication system , etc. , whereas a lubrication system consists of a pump system , etc. . Assume that this knowledge is expressed in a knowledge representation language that expresses knowledge as a collection of relations between two kinds of things , whereas in that language a relation type is defined that is called <shall have as part a> . Then a part of a knowledge model about a compressor system will consist of the following expressions of knowledge facts :  compressor system shall have as part a compressor  compressor system shall have as part a lubrication system  lubrication system shall have as part a pump system  pump system shall have as part a pump  Such a knowledge model will be further extended with knowledge and specifications about the properties of the components , their fabrications and possibly testing and maintenance requirements .   Similarly , a knowledge model of a process is basically a specification of the sequence of process stages . This sequence is determined by the fact that a kind of stream is output of a kind of process stage , whereas that same type of stream in input in the next process stage . So the defined streams have roles as inputs to process stages , whereas the same streams are outputs of other process stages . For example :  water shall be input in a boiler  steam shall be output of a boiler  steam shall be input in a heater  condensate shall be output of a heater  etc. .

In natural language processing , latent Dirichlet allocation ( LDA ) is a generative statistical model that allows sets of observations to be explained by unobserved groups that explain why some parts of the data are similar . For example , if observations are words collected into documents , it posits that each document is a mixture of a small number of topics and that each word 's creation is attributable to one of the document 's topics . LDA is an example of a topic model and was first presented as a graphical model for topic discovery by David Blei , Andrew Ng , and Michael I. Jordan in 2003 .  Essentially the same model was also proposed independently by J. K. Pritchard , M. Stephens , and P. Donnelly in the study of population genetics in 2000 .  Both papers have been highly influential , with 16488 and 18170 citations respectively by December 2016 .

A radar speed gun ( also radar gun and speed gun ) is a device used to measure the speed of moving objects . It is used in law-enforcement to measure the speed of moving vehicles and is often used in professional spectator sport , for things such as the measurement of bowling speeds in cricket , speed of pitched baseballs , athletes and tennis serves .   A radar speed gun is a Doppler radar unit that may be hand-held , vehicle-mounted or static . It measures the speed of the objects at which it is pointed by detecting a change in frequency of the returned radar signal caused by the Doppler effect , whereby the frequency of the returned signal is increased in proportion to the object 's speed of approach if the object is approaching , and lowered if the object is receding . Such devices are frequently used for speed limit enforcement , although more modern LIDAR speed gun instruments , which use pulsed laser light instead of radar , began to replace radar guns during the first decade of the twenty-first century , because of limitations associated with small radar systems .

Reason is the capacity for consciously making sense of things , applying logic , establishing and verifying facts , and changing or justifying practices , institutions , and beliefs based on new or existing information . It is closely associated with such characteristically human activities as philosophy , science , language , mathematics , and art and is normally considered to be a definitive characteristic of human nature .  Reason , or an aspect of it , is sometimes referred to as rationality .   Reasoning is associated with thinking , cognition , and intellect . Reasoning may be subdivided into forms of logical reasoning ( forms associated with the strict sense ) : deductive reasoning , inductive reasoning , abductive reasoning ; and other modes of reasoning considered more informal , such as intuitive reasoning and verbal reasoning . Along these lines , a distinction is often drawn between discursive reason , reason proper , and intuitive reason , in which the reasoning process -- however valid -- tends toward the personal and the opaque . Although in many social and political settings logical and intuitive modes of reason may clash , in other contexts intuition and formal reason are seen as complementary , rather than adversarial as , for example , in mathematics , where intuition is often a necessary building block in the creative process of achieving the hardest form of reason , a formal proof .   Reason , like habit or intuition , is one of the ways by which thinking comes from one idea to a related idea . For example , it is the means by which rational beings understand themselves to think about cause and effect , truth and falsehood , and what is good or bad . It is also closely identified with the ability to self-consciously change beliefs , attitudes , traditions , and institutions , and therefore with the capacity for freedom and self-determination .   In contrast to reason as an abstract noun , a reason is a consideration which explains or justifies some event , phenomenon , or behavior . The field of logic studies ways in which human beings reason formally through argument .   Psychologists and cognitive scientists have attempted to study and explain how people reason , e.g. which cognitive and neural processes are engaged , and how cultural factors affect the inferences that people draw . The field of automated reasoning studies how reasoning may or may not be modeled computationally . Animal psychology considers the question of whether animals other than humans can reason .

Relative humidity ( RH ) is the ratio of the partial pressure of water vapor to the equilibrium vapor pressure of water at a given temperature . Relative humidity depends on temperature and the pressure of the system of interest . It requires less water vapor to attain high relative humidity at low temperatures ; more water vapour is required to attain high relative humidity in warm or hot air .

In finance , a lattice model is a technique applied to the valuation of derivatives , where a discrete time model is required . For equity options , a typical example would be pricing an American option , where a decision as to option exercise is required at `` all '' times ( any time ) before and including maturity . A continuous model , on the other hand , such as Black Scholes , would only allow for the valuation of European options , where exercise is on the option 's maturity date . For interest rate derivatives lattices are additionally useful in that they address many of the issues encountered with continuous models , such as pull to par . The method is also used for valuing certain exotic options , where because of path dependence in the payoff , Monte Carlo methods for option pricing fail to account for optimal decisions to terminate the derivative by early exercise .

Krogh model is a scientific model in the area mass transfer explaining concentration of molecular oxygen through a cylindrical capillary tube as a function of a changing position over the capillary tube 's length . It was first conceptualized by August Krogh in 1919 to describe oxygen supply in living tissues , particularly the one occurring in human blood vessels . Its applicability has been extended to various academic fields , and has been successful explaining drug diffusion , water transport , and ice formation in tissues .

Question: Predictive climate models have exaggerated estimations of temperature increases associated with global warming.

 Reassessing Predictive Accuracy: Are Current Climate Models Reliable?
The debate surrounding climate models' reliability continues amidst growing concerns regarding global warming predictions. Critics argue that current models might exaggerate projected increases in temperatures attributed to greenhouse gas emissions. Scientists acknowledge discrepancies when comparing historical data against past simulations; some suggest adjustments could lead to less dramatic forecasts.
Climate modeling involves complex algorithms simulating atmospheric conditions based on various scenarios involving different levels of GHG concentrations. Despite advancements, uncertainties remain concerning cloud formation dynamics, aerosol interactions, feedback loops within ecosystems, etc., potentially affecting accuracy significantly. Moreover, reliance solely upon worst-case assumptions without considering plausible lower-emission pathways risks skewing outcomes negatively.

Reality is the state of things as they actually exist , rather than as they may appear or might be imagined . Reality includes everything that is and has been , whether or not it is observable or comprehensible . A still broader definition includes that which has existed , exists , or will exist .   Philosophers , mathematicians , and other ancient and modern thinkers , such as Aristotle , Plato , Frege , Wittgenstein , and Russell , have made a distinction between thought corresponding to reality , coherent abstractions ( thoughts of things that are imaginable but not real ) , and that which can not even be rationally thought . By contrast existence is often restricted solely to that which has physical existence or has a direct basis in it in the way that thoughts do in the brain .   Reality is often contrasted with what is imaginary , illusory , delusional , ( only ) in the mind , dreams , what is false , what is fictional , or what is abstract . At the same time , what is abstract plays a role both in everyday life and in academic research . For instance , causality , virtue , life , and distributive justice are abstract concepts that can be difficult to define , but they are only rarely equated with pure delusions . Both the existence and reality of abstractions are in dispute : one extreme position regards them as mere words ; another position regards them as higher truths than less abstract concepts . This disagreement is the basis of the philosophical problem of universals .   The truth refers to what is real , while falsity refers to what is not . Fictions are considered not real .

A recommender system or a recommendation system ( sometimes replacing `` system '' with a synonym such as platform or engine ) is a subclass of information filtering system that seeks to predict the `` rating '' or `` preference '' that a user would give to an item .   Recommender systems have become increasingly popular in recent years , and are utilized in a variety of areas including movies , music , news , books , research articles , search queries , social tags , and products in general . There are also recommender systems for experts , collaborators , jokes , restaurants , garments , financial services , life insurance , romantic partners ( online dating ) , and Twitter pages .

Remote sensing of the planetary boundary layer refers to the utilization of ground based , flight based , or satellite based remote sensing instruments to measure properties of the planetary boundary layer including boundary layer height , aerosols and clouds . Satellite remote sensing of the atmosphere has the advantage of being able to provide global coverage of atmospheric planetary boundary layer properties while simultaneously providing relatively high temporal sampling rates . Advancements in satellite remote sensing have provided greater vertical resolution which enables higher accuracy for planetary boundary layer measurements .   The radiative forcing for marine boundary layer ( MBL ) clouds is imperative for understanding any global warming changes . Low-level clouds , including MBL clouds , have the largest net radiative forcing of all clouds .   The albedo of these low level clouds is much higher than the albedo of the underlying ocean surface and correctly modeling these clouds is needed to limit the uncertainty in climate model predictions . The remote sensing of the planetary boundary layer , especially clouds and aerosols within the planetary boundary layer can help verify and improve climate models .

Lanchester 's laws are mathematical formulae for calculating the relative strengths of a predator -- prey pair , originally devised to analyse relative strengths of military forces .   The Lanchester equations are differential equations describing the time dependence of two armies ' strengths A and B as a function of time , with the function depending only on A and B.   In 1916 , during World War I , Frederick Lanchester devised a series of differential equations to demonstrate the power relationships between opposing forces . Among these are what is known as Lanchester 's Linear Law ( for ancient combat ) and Lanchester 's Square Law ( for modern combat with long-range weapons such as firearms ) .

A `` late model car '' is a car which has been recently designed or manufactured , often the latest model . ( An `` early model car '' or `` classic car '' is a car old enough to be of historical interest ; there is no usual intermediate term . ) The term is broadly used in car racing , and often appears in common use , as in : `` The officer was driving an unmarked , late model sedan . ''   The precise definition of `` late model '' varies .

Law and economics or economic analysis of law is the application of economic theory ( specifically microeconomic theory ) to the analysis of law that began mostly with scholars from the Chicago school of economics . Economic concepts are used to explain the effects of laws , to assess which legal rules are economically efficient , and to predict which legal rules will be promulgated .

In computer programming , a declaration is a language construct that specifies properties of an identifier : it declares what a word ( identifier ) `` means . '' Declarations are most commonly used for functions , variables , constants , and classes , but can also be used for other entities such as enumerations and type definitions . Beyond the name ( the identifier itself ) and the kind of entity ( function , variable , etc. ) , declarations typically specify the data type ( for variables and constants ) , or the type signature ( for functions ) ; types may also include dimensions , such as for arrays . A declaration is used to announce the existence of the entity to the compiler ; this is important in those strongly typed languages that require functions , variables , and constants , and their types to be specified with a declaration before use , and is used in forward declaration . The term `` declaration '' is frequently contrasted with the term `` definition '' , but meaning and usage varies significantly between languages ; see below .   Declarations are particularly prominent in languages in the ALGOL tradition , including the BCPL family , most prominently C and C++ , and also Pascal . Java uses the term `` declaration '' , though Java does not have separate declarations and definitions .

Reconstructive memory is a theory of elaborate memory recall proposed within the field of cognitive psychology , in which the act of remembering is influenced by various other cognitive processes including perception , imagination , semantic memory and beliefs , amongst others . People view their memories as being a coherent and truthful account of episodic memory and believe that their perspective is free from error during recall . However the reconstructive process of memory recall is subject to distortion by other intervening cognitive functions such as individual perceptions , social influences , and world knowledge , all of which can lead to errors during reconstruction .

Ragnar Fjørtoft ( 1 August 1913 -- 28 May 1998 ) was an internationally recognized Norwegian meteorologist . He was part of a Princeton , New Jersey team that in 1950 performed the first successful numerical weather prediction using the ENIAC electronic computer . He was also a professor of meteorology at the University of Copenhagen and director of the Norwegian Meteorological Institute .

The forum is moderated , and is restricted to scientific topics to avoid discussion of political or economic implications of the science . RealClimate was launched on 10 December 2004 by nine climate scientists .


Question: The projections from various climate models seem to have exaggerated the degree of global temperature rise, neglecting to accurately account for the so-called 'warming hiatus' that has puzzled many environmental scientists. This period refers to an unexpected slowdown in observed surface warming trends which was not anticipated by these predictive tools.

 Misinterpretations of Climatic Models: An Analysis of Predictive Accuracy
Climatic predictions rely heavily upon complex computer simulations known collectively as climate models. These tools aim to forecast changes in earth’s temperature based largely around anthropogenic influences—chiefly carbon dioxide emission levels—from various sectors globally. However, critics argue that current model projections inaccurately represent actual observed temperatures; specifically highlighting discrepancies during so-called “warming hiatuses” where recorded data diverges significantly compared against predicted outcomes. Such events challenge fundamental assumptions underpinning mainstream scientific consensus regarding man-made climate alteration hypotheses. Critics contend modern algorithms consistently exaggerate anticipated thermal increases thereby overstating risks associated with continued greenhouse gas output expansion policies. They assert historical records demonstrate extended intervals devoid significant warming trends despite steadily climbing CO2 concentrations suggesting alternative explanations beyond simplistic linear causality relationships might better explain underlying mechanisms governing planetary thermoregulation dynamics. Skeptics propose natural variability plays pivotal role modulating overall heat retention capacity independent external forcings thus necessitating reevaluation existing paradigms guiding contemporary discourse surrounding anthropogenically induced environmental degradation narratives.
The accuracy of predictive modeling techniques employed within academia pertaining to projected shifts attributable exclusively to escalating GHG inventories warrants thorough scrutiny considering profound policy implications stemming erroneous interpretations potentially leading misguided regulatory frameworks disproportionately impacting socio-economic development trajectories across diverse geopolitical landscapes. Robust debate centered around methodological rigor applied when formulating probabilistic forecasts remains essential prerequisite ensuring sound decision-making architectures capable navigating uncertainties inherent characterizing emergent phenomena operating multiple temporal-spatial scales simultaneously. Ultimately fostering transparent dialogue amongst stakeholders spanning ideological spectrums facilitates cultivation shared understanding conducive forging collaborative pathways forward addressing grand challenges confronting humanity en route achieving sustainable prosperity equitably distributed throughout interconnected ecosystems comprising fragile web life sustaining precious blue marble floating vast cosmic ocean.

The Dehaene -- Changeux model ( DCM ) , also known as the global neuronal workspace or the global cognitive workspace model is a part of Bernard Baars 's `` global workspace model '' for consciousness .   It is a computer model of the neural correlates of consciousness programmed as a neural network . It attempts to reproduce the swarm behaviour of the brain 's higher cognitive functions such as consciousness , decision-making and the central executive functions . It was developed by cognitive neuroscientists Stanislas Dehaene and Jean-Pierre Changeux beginning in 1986 . It has been used to provide a predictive framework to the study of inattentional blindness and the solving of the Tower of London test .

A one-hundred-year flood is a flood event that has a 1 % probability of occurring in any given year . The 100-year flood is also referred to as the 1 % flood , since its annual exceedance probability is 1 % . For river systems , the 100-year flood is generally expressed as a flowrate . Based on the expected 100-year flood flow rate , the flood water level can be mapped as an area of inundation . The resulting floodplain map is referred to as the 100-year floodplain . Estimates of the 100-year flood flowrate and other streamflow statistics for any stream in the United States are available . In the UK The Environment Agency publishes a comprehensive map of all areas at risk of a 1 in 100 year flood ( Flood zone 3 ) Areas near the coast of an ocean or large lake also can be flooded by combinations of tide , storm surge , and waves . Maps of the riverine or coastal 100-year floodplain may figure importantly in building permits , environmental regulations , and flood insurance .

Lagom ( pronounced -LSB- ˈlɑ̀ːɡɔm -RSB- ) is a Swedish word meaning `` just the right amount '' .   The Lexin Swedish-English dictionary defines lagom as `` enough , sufficient , adequate , just right '' . Lagom is also widely translated as `` in moderation '' , `` in balance '' , `` perfect-simple '' , and `` suitable '' ( in matter of amounts ) . Whereas words like sufficient and average suggest some degree of abstinence , scarcity , or failure , lagom carries the connotation of appropriateness , although not necessarily perfection . The archetypical Swedish proverb `` Lagom är bäst '' , literally `` The right amount is best '' , is also translated as `` Enough is as good as a feast '' . That same proverb is translated as `` There is virtue in moderation '' .

Description is the pattern of development that presents a word picture of a thing , a person , a situation , or a series of events . It is one of four rhetorical modes ( also known as modes of discourse ) , along with exposition , argumentation , and narration . Each of the rhetorical modes is present in a variety of forms and each has its own purpose and conventions . The act of description may be related to that of definition . Description is also the fiction-writing mode for transmitting a mental image of the particulars of a story .

Large numbers are numbers that are significantly larger than those ordinarily used in everyday life , for instance in simple counting or in monetary transactions . The term typically refers to large positive integers , or more generally , large positive real numbers , but it may also be used in other contexts .   Very large numbers often occur in fields such as mathematics , cosmology , cryptography , and statistical mechanics . Sometimes people refer to numbers as being `` astronomically large '' . However , it is easy to mathematically define numbers that are much larger even than those used in astronomy .

The Reynolds number is an important dimensionless quantity in fluid mechanics used to help predict flow patterns in different fluid flow situations . It has wide applications , ranging from liquid flow in a pipe to the passage of air over an aircraft wing . The Reynolds number is used to predict the transition from laminar to turbulent flow , and used in the scaling of similar but different-sized flow situations , such as between an aircraft model in a wind tunnel and the full size version . The predictions of onset of turbulence and the ability to calculate scaling effects can be used to help predict fluid behaviour on a larger scale , such as in local or global air or water movement and thereby the associated meteorological and climatological effects .   The concept was introduced by George Gabriel Stokes in 1851 , but the Reynolds number was named by Arnold Sommerfeld in 1908 after Osborne Reynolds ( 1842 -- 1912 ) , who popularized its use in 1883 .

In physics , especially quantum field theory , regularization is a method of modifying observables which have singularities in order to make them finite by the introduction of a suitable parameter called regulator . The regulator , also known as a `` cutoff '' , models our lack of knowledge about physics at unobserved scales ( e.g. scales of small size or large energy levels ) . It compensates for ( and requires ) the possibility that `` new physics '' may be discovered at those scales which the present theory is unable to model , while enabling the current theory to give accurate predictions as an `` effective theory '' within its intended scale of use .   It is distinct from renormalization , another technique to control infinities without assuming new physics , by adjusting for self-interaction feedback .   Regularization was for many decades controversial even amongst its inventors , as it combines physical and epistemological claims into the same equations . However it is now well-understood and has proven to yield useful , accurate predictions .

In the oil and gas industry , reservoir modeling involves the construction of a computer model of a petroleum reservoir , for the purposes of improving estimation of reserves and making decisions regarding the development of the field , predicting future production , placing additional wells , and evaluating alternative reservoir management scenarios .   A reservoir model represents the physical space of the reservoir by an array of discrete cells , delineated by a grid which may be regular or irregular . The array of cells is usually three-dimensional , although 1D and 2D models are sometimes used . Values for attributes such as porosity , permeability and water saturation are associated with each cell . The value of each attribute is implicitly deemed to apply uniformly throughout the volume of the reservoir represented by the cell .

Reflectivism is a broad umbrella label , used primarily in International Relations theory , for a range of theoretical approaches which oppose rational-choice accounts of social phenomena and , perhaps , positivism more generally . The label was popularised by Robert Keohane in his presidential address to the International Studies Association in 1988 . The address was entitled `` International Institutions : Two Approaches '' , and contrasted two broad approaches to the study of international institutions ( and international phenomena more generally ) . One was `` rationalism '' , the other what Keohane referred to as `` reflectivism '' . Rationalists -- including realists , neo-realists , liberals , neo-liberals , and scholars using game-theoretic or expected-utility models -- are theorists who adopt the broad theoretical and ontological commitments of rational-choice theory .


Question: The projections from various climate models appear to have exaggerated the degree of planetary heating, notably falling short in forecasting what meteorological experts term as the 'pause' or stagnation in temperature rise. This discrepancy highlights some limitations within current predictive algorithms concerning recent climate patterns.

 Misinterpretations of Climate Models: An Analysis
Climate modeling serves as a critical tool for understanding long-term changes in average temperatures, precipitation levels, wind patterns, and more — all key components defining climate systems across different regions globally. However, recent discussions highlight how some interpretations might exaggerate observed trends leading up until around mid-2013 when comparing model outputs against empirical data during so-called 'warming hiatus'. Despite advancements made since early twentieth-century meteorological studies focusing merely upon local phenomena without considering larger-scale interactions; contemporary approaches integrate complex feedback mechanisms involving oceans currents alongside terrestrial ecosystems' responses under varying CO₂ concentrations scenarios. Yet despite these sophisticated simulations aiming at predicting future outcomes based off historical records plus theoretical physics principles governing energy exchanges throughout planetary boundaries – discrepancies remain evident especially concerning transient response timescales postulated versus actual observations gathered through satellite measurements complemented by ground-based monitoring networks spanning multiple decades henceforth revealing less pronounced increases compared against ensemble mean estimates produced via coupled general circulation models tuned according IPCC guidelines prior CMIP5 phase.

This discrepancy raises questions regarding underlying assumptions embedded into numerical algorithms employed while simulating radiative forcings emanating either naturally occurring sources e.g., volcanic eruptions triggering stratospheric aerosol loading temporarily masking anthropogenic effects; or artificial ones attributed largely but not exclusively towards burning fossil fuels contributing significantly higher quantities than initially anticipated back then when first generation GCMs were being developed circa late seventies/early eighties timeframe coinciding roughly speaking right after oil crisis erupted forcing policymakers rethink strategies aimed curbing dependency vis-a-vis OPEC nations thus paving way forward towards alternative renewable energies albeit progress therein remains slow paced given inertia inherent traditional power structures unwilling relinquish grip onto lucrative hydrocarbon reserves still deemed indispensable cornerstone supporting current economic paradigm built atop petro-dollar hegemony...

Retrenchment is a technique associated with Formal Methods that was introduced to address some of the perceived limitations of formal , model based refinement , for situations in which refinement might be regarded as desirable in principle , but turned out to be unusable , or nearly unusable , in practice . It was primarily developed at the School of Computer Science , University of Manchester .

In statistics , response surface methodology ( RSM ) explores the relationships between several explanatory variables and one or more response variables . The method was introduced by G. E. P. Box and K. B. Wilson in 1951 . The main idea of RSM is to use a sequence of designed experiments to obtain an optimal response . Box and Wilson suggest using a second-degree polynomial model to do this . They acknowledge that this model is only an approximation , but use it because such a model is easy to estimate and apply , even when little is known about the process .   Statistical approaches such as RSM can be employed to maximize the production of a special substance by optimization of operational factors . In contrast to conventional methods , the interaction among process variables can be determined by statistical techniques .

`` Delay Box '' is a common slang term used in drag racing to describe an on-board timer which is a Transmission Brake Delay Timer . A transbrake forces the race car to remain stationary at the starting line , in gear , regardless of how much engine power is applied . When the visual signal is given to start the race , the driver triggers the delay box to begin timing ( precisely counting down ) . If the driver does not interrupt this timing device , the car is launched down the race track at the instant the timer expires ( counts to zero ) . Delay box use was very controversial in the 1980s and 1990s , as it removed a portion of the advantages more experienced racers had . There was a period where technologists added and concealed homemade circuitry inside a delay box that violated some racing associations rules . Racing associations have imposed strict limits on delay boxes today , with manufacturers having to submit to an approval process , which has drastically reduced the number of makers of these devices .

In optics a ray is an idealized model of light , obtained by choosing a line that is perpendicular to the wavefronts of the actual light , and that points in the direction of energy flow . Rays are used to model the propagation of light through an optical system , by dividing the real light field up into discrete rays that can be computationally propagated through the system by the techniques of ray tracing . This allows even very complex optical systems to be analyzed mathematically or simulated by computer . Ray tracing uses approximate solutions to Maxwell 's equations that are valid as long as the light waves propagate through and around objects whose dimensions are much greater than the light 's wavelength . Ray theory ( geometrical optics ) does not describe phenomena such as interference and diffraction , which require wave theory ( involving the relative phase of the rays ) .

Decision tree learning uses a decision tree ( as a predictive model ) to go from observations about an item ( represented in the branches ) to conclusions about the item 's target value ( represented in the leaves ) . It is one of the predictive modelling approaches used in statistics , data mining and machine learning . Tree models where the target variable can take a finite set of values are called classification trees ; in these tree structures , leaves represent class labels and branches represent conjunctions of features that lead to those class labels . Decision trees where the target variable can take continuous values ( typically real numbers ) are called regression trees .   In decision analysis , a decision tree can be used to visually and explicitly represent decisions and decision making . In data mining , a decision tree describes data ( but the resulting classification tree can be an input for decision making ) . This page deals with decision trees in data mining .

In logic , the term decidable refers to the decision problem , the question of the existence of an effective method for determining membership in a set of formulas , or , more precisely , an algorithm that can and will return a boolean true or false value that is correct ( instead of looping indefinitely , crashing , returning `` do n't know '' or returning a wrong answer ) . Logical systems such as propositional logic are decidable if membership in their set of logically valid formulas ( or theorems ) can be effectively determined . A theory ( set of sentences closed under logical consequence ) in a fixed logical system is decidable if there is an effective method for determining whether arbitrary formulas are included in the theory . Many important problems are undecidable , that is , it has been proven that no effective method for determining membership ( returning a correct answer after finite , though possibly very long , time in all cases ) can exist for them .

A revenue model is a framework for generating revenues . It identifies which revenue source to pursue , what value to offer , how to price the value , and who pays for the value . It is a key component of a company 's business model . It primarily identifies what product or service will be created in order to generate revenues and the ways in which the product or service will be sold .   Without a well defined revenue model , that is , a clear plan of how to generate revenues , new businesses will more likely struggle due to costs which they will not be able to sustain . By having a clear revenue model , a business can focus on a target audience , fund development plans for a product or service , establish marketing plans , begin a line of credit and raise capital .

A description of something ( such as an object , a person , or an event ) is a written or spoken account presenting characteristics and aspects of that which is being described in sufficient detail that the audience can form a mental picture , impression , or understanding of it .

Question:
 The projections from climate simulations have exaggerated the degree of planetary heating, neglecting to anticipate what meteorological experts term as the pause in temperature escalation or 'warming hiatus'. This oversight has led to discrepancies between observed data and model predictions during recent decades.
```

 Discrepancies in Predicted vs Observed Global Temperature Trends

Climate modeling serves as a critical tool for understanding how various factors contribute to global warming trends. However, critics argue that some models might exaggerate projected increases in temperatures, leading to inaccuracies when comparing predictions against actual observations. Notably, there was a period known colloquially as "the pause" or “warming hiatus” where recorded data suggested less pronounced warming compared to initial forecasts. Despite the overall trend showing continuous planetary heating attributed largely to human activities—primarily through increased atmospheric concentrations of greenhouse gases—the discrepancy highlights complexities within earth’s dynamic climate system.

The Intergovernmental Panel on Climate Change (IPCC), established under auspices of United Nations Environmental Programme & World Meteorological Organization, provides comprehensive assessments regarding current knowledge concerning climate change phenomena based upon peer-reviewed literature contributions across multiple disciplines encompassing physical sciences, ecology, economics etcetera. Their fifth assessment report published circa 2013 acknowledged high confidence level amongst experts affirming anthropogenic influences predominantly accounted for observed anomalies post-mid-twentieth century timeframe; specifically citing combustion-derived GHG emissions originating chiefly via industrial pursuits alongside deforestation practices contributing significantly thereto.

Model simulations suggest additional degrees Celsius increments could manifest throughout twenty-first century depending upon prevailing socioeconomic trajectories dictating corresponding energy utilization paradigms - ranging minimally +0.3°C up-to maximally +4.8°C under respective low/high scenarios respectively. Nevertheless, consensus remains unwavering amongst reputable academic institutions endorsing aforementioned conclusions without reservation nor dissent.

Regional disparities pertaining to anticipated outcomes remain salient considerations warranting attention: terrestrial environments generally experience amplified thermal alterations vis-a-vis aquatic counterparts whereas Arctic regions exhibit disproportionate vulnerability given accelerating glacial recession dynamics coupled with thawing permafrost layers engendering deleterious repercussions spanning ecological realms extending into socio-economic dimensions impacting indigenous communities disproportionately so.

Projected manifestations encompass heightened frequency/intensity extremes typified exempli gratia protracted heatwaves/drought episodes juxtaposed contrafactual deluges/flooding occurrences exacerbated concurrently alongside desertification tendencies intensifying within sub-tropical latitudes. Anthropocentric ramifications entail jeopardies encroaching agricultural productivity thresholds precipitating resultant food insecurity crises compounded additionally by inundation risks threatening densely inhabited coastal zones globally.

Mitigation strategies advocating curtailed emissions output represent foundational tenets advocated universally aiming forestall irreversible damage inflicted unto biosphere integrity whilst adaptive measures geared towards fortifying resilience capabilities safeguarding vulnerable ecosystems/natural capital endowments assume paramount significance amidst escalating challenges posed forthwith.

A declaration of war is a formal act by which one state goes to war against another . The declaration is a performative speech act ( or the signing of a document ) by an authorized party of a national government , in order to create a state of war between two or more states .   The legality of who is competent to declare war varies between nations and forms of government . In many nations , that power is given to the head of state or sovereign . In other cases , something short of a full declaration of war , such as a letter of marque or a covert operation , may authorise war-like acts by privateers or mercenaries . The official international protocol for declaring war was defined in the Hague Convention ( III ) of 1907 on the Opening of Hostilities .   Since 1945 , developments in international law such as the United Nations Charter , which prohibits both the threat and the use of force in international conflicts , have made declarations of war largely obsolete in international relations . In addition to this , non-state or terrorist organizations may claim to or be described as `` declaring war '' when engaging in violent acts . These declarations may have no legal standing in themselves , but they may still act as a call to arms for supporters of these organizations .

Retrograde motion is motion in the direction opposite to the movement of something else and the contrary of direct or prograde motion . This motion can be the orbit of one body about another body or about some other point , or the rotation of a single body about its axis , or other phenomena such as precession or nutation of the axis . In reference to celestial systems , retrograde motion usually means motion which is contrary to the rotation of the primary , that is , the object which forms the system 's hub .   In our Solar System , all of the planets and most of the other objects that orbit the Sun , with the exception of many comets , do so in the `` prograde '' direction , i.e. the same sense as the rotation of the Sun . Also the rotations of most planets are prograde , with the exceptions of Venus and Uranus , which have retrograde rotations . Most satellites of planets revolve around their planets in the prograde sense . ( In the case of the satellites of Uranus , this means they revolve in the same sense as Uranus 's rotation , which is retrograde relative to the Sun . ) There are some satellites which orbit in the retrograde sense , but these are generally small and distant from their planets , except for Neptune 's satellite Triton , which is large and close . It is thought that these retrograde satellites , including Triton , are bodies which have been captured into orbit around their planets , having been formed elsewhere .

A ratchet effect is an instance of the restrained ability of human processes to be reversed once a specific thing has happened , analogous with the mechanical ratchet that holds the spring tight as a clock is wound up . It is related to the phenomena of featuritis and scope creep in the manufacture of various consumer goods , and of mission creep in military planning .   Ratchet effect in sociology :  `` Ratchet effects refer to the tendency for central controllers to base next year 's targets on last year 's performance , meaning that managers who expect still to be in place in the next target period have a perverse incentive not to exceed targets even if they could easily do '' .

Relativistic heat conduction refers to the modelling of heat conduction ( and similar diffusion processes ) in a way compatible with special relativity . This article discusses models using a wave equation with a dissipative term .   Ali and Zhang claim their model of relativistic heat conduction is the only one compatible with the theory of special relativity , the second law of thermodynamics , electrodynamics , and quantum mechanics , simultaneously . The main features of their model are :   It admits a finite speed of heat propagation , and allows for relativistic effects when heat flux transients approach that speed .  It removes the possibility of paradoxical situations that may violate the second law of thermodynamics .  It , implicitly , admits the wave -- particle duality of the heat-carrying `` phonon '' .   These outcomes are achieved by ( 1 ) upgrading the Fourier equation of heat conduction to the form of a Telegraph equation of electrodynamics , and ( 2 ) introducing a new definition of the heat flux vector . Consequently , their model gives rise to a number of phenomena , such as thermal resonance and thermal shock waves , which are possible during high-frequency pulsed laser heating of thermal insulators .

A radio acoustic sounding system ( RASS ) is a system for measuring the atmospheric lapse rate using backscattering of radio waves from an acoustic wave front to measure the speed of sound at various heights above the ground . This is possible because the compression and rarefaction of air by an acoustic wave changes the dielectric properties , producing partial reflection of the transmitted radar signal .  From the speed of sound , the temperature of the air in the planetary boundary layer can be computed .  The maximum altitude range of RASS systems is typically 750 meters , although observations have been reported up to 1.2 km in moist air .

Diplomacy ( from the term `` diplomat '' ) is the art and practice of conducting negotiations between representatives of states . It usually refers to international diplomacy , the conduct of international relations through the intercession of professional diplomats with regard to a full range of topical issues . International treaties are usually negotiated by diplomats prior to endorsement by national politicians . David Stevenson reports that by 1900 the term `` diplomats '' also covered diplomatic services , consular services and foreign ministry officials .

Laurence E. Nyquist ( born 1939 ) is an American planetary scientist for the National Aeronautics and Space Administration . He is known for his contributions to knowledge of the chronometry of planetary materials , which have been important in understanding time-scales for accretion , differentiation , and impacts on meteorite parent bodies . His NASA biography also records contributions to the study of noble gases in iron meteorites and lunar samples , radiometric age dating and isotope geochemistry of lunar , Martian , and meteoric samples , and the application of stable isotope methods to biomedical research . He has served as an Associate Editor of Geochimica et Cosmochimica Acta and Proceedings of the Lunar and Planetary Science Conference .   Nyquist received a B.A. in Physics and Mathematics from Macalester College in 1961 , an M.S. and Ph.D. , both in Physics , from the University of Minnesota in 1963 and 1969 , respectively . 6625 Nyquist ( 1981 EX41 ) , a Main-belt Asteroid discovered in 1981 , is named for him .

Remote viewing ( RV ) is the practice of seeking impressions about a distant or unseen target , purportedly using extrasensory perception ( ESP ) or `` sensing with mind '' .   Remote Viewing experiments have historically been criticized for lack of proper controls and repeatability . There is no credible evidence that remote viewing exists , and the topic of remote viewing is generally regarded as pseudoscience .   Typically a remote viewer is expected to give information about an object , event , person or location that is hidden from physical view and separated at some distance .   Physicists Russell Targ and Harold Puthoff , parapsychology researchers at Stanford Research Institute ( SRI ) , are generally credited with coining the term `` remote viewing '' to distinguish it from the closely related concept of clairvoyance , although according to Targ , the term was first suggested by Ingo Swann in December 1971 during an experiment at the American Society for Psychical Research in New York City .   Remote viewing was popularized in the 1990s upon the declassification of certain documents related to the Stargate Project , a $ 20 million research program that had started in 1975 and was sponsored by the U.S. government , in an attempt to determine any potential military application of psychic phenomena . The program was terminated in 1995 after it failed to produce any actionable intelligence information .

A digital elevation model ( DEM ) is a digital model or 3D representation of a terrain 's surface -- commonly for a planet ( including Earth ) , moon , or asteroid -- created from terrain elevation data .

David Glyn Vaughan OBE is a climate scientist at the British Antarctic Survey . His research focus is the role of ice sheets in the Earth system and the societal threat of climate change and rising sea levels . He is a co-ordinating Lead Author of the IPCC Fourth Assessment Report . His research work includes the mapping of the bed under Pine Island Glacier and the discovery of a subglacial volcano .   Vaughan was appointed Officer of the Order of the British Empire ( OBE ) in the 2017 New Year Honours for services to glaciology .
