 Controversies Surrounding Historical Climate Changes: The Case Studies of the Medieval Warm Period & Little Ice Age
Historical climate studies often spark debates among scientists, particularly concerning two significant periods - the Medieval Warm Period (MWP), sometimes referred to as the Medieval Climate Optimum or Medieval Climatic Anomaly, alongside its subsequent era, the Little Ice Age. These epochs highlight fluctuations in regional climates across various parts of the globe, notably affecting Europe and Asia, spanning roughly from AD 950-1250 until approximately 1850 respectively. Notably, while the MWP brought warmer conditions predominantly within the North Atlantic realm, leading into colder trends later classified under what we now know as 'the little ice age'.

Despite limitations regarding pre-industrial era datasets before circa year 1600 CE when reliable instrumental measurements became available; reconstructions suggest that indeed there existed phases where average air temperatures reached levels comparable even higher relative modern-day values specifically confined inside certain geographical locations rather universally spread phenomena observed nowadays attributed largely anthropogenic influences exacerbating ongoing naturally occurring variations. However, overall analyses indicate global mean figures remained lower compared against contemporary readings despite localized anomalies experienced throughout medieval ages reflecting complex interplay intrinsic earth system dynamics involving multiple forcings e.g., solar irradiance variability, reduced aerosol loading etcetera.

Potential mechanisms proposed explaining anomalous warmth exhibited during so-called "medieval optimum" encompass enhanced insolation output attributable prolonged grand maxima phase sunspot cycle coinciding timeframe plus suppressed frequency magnitude explosive eruptions contributing stratospheric sulfate veil thinning allowing greater penetration shortwave radiation reaching planetary surfaces.

Deinonychus ( -LSB- daɪˈnɒnᵻkəs -RSB- ; δεινός , ` terrible ' and ὄνυξ , genitive ὄνυχος ` claw ' ) is a genus of carnivorous dromaeosaurid coelurosaurian dinosaurs , with one described species , Deinonychus antirrhopus . This species , which could grow up to 3.4 m long , lived during the early Cretaceous Period , about 115 -- 108 million years ago ( from the mid-Aptian to early Albian stages ) . Fossils have been recovered from the U.S. states of Montana , Utah , Wyoming , and Oklahoma , in rocks of the Cloverly Formation , Cedar Mountain Formation and Antlers Formation , though teeth that may belong to Deinonychus have been found much farther east in Maryland .   Paleontologist John Ostrom 's study of Deinonychus in the late 1960s revolutionized the way scientists thought about dinosaurs , leading to the `` dinosaur renaissance '' and igniting the debate on whether dinosaurs were warm-blooded or cold blooded . Before this , the popular conception of dinosaurs had been one of plodding , reptilian giants . Ostrom noted the small body , sleek , horizontal posture , ratite-like spine , and especially the enlarged raptorial claws on the feet , which suggested an active , agile predator .   `` Terrible claw '' refers to the unusually large , sickle-shaped talon on the second toe of each hind foot . The fossil YPM 5205 preserves a large , strongly curved ungual . In life , archosaurs have a horny sheath over this bone , which extends the length . Ostrom looked at crocodile and bird claws and reconstructed the claw for YPM 5205 as over 120 mm long . The species name antirrhopus means `` counter balance '' , which refers to Ostrom 's idea about the function of the tail . As in other dromaeosaurids , the tail vertebrae have a series of ossified tendons and super-elongated bone processes . These features seemed to make the tail into a stiff counterbalance , but a fossil of the very closely related Velociraptor mongoliensis ( IGM 100/986 ) has an articulated tail skeleton that is curved laterally in a long S-shape . This suggests that , in life , the tail could bend to the sides with a high degree of flexibility . In both the Cloverly and Antlers formations , Deinonychus remains have been found closely associated with those of the ornithopod Tenontosaurus . Teeth discovered associated with Tenontosaurus specimens imply they were hunted , or at least scavenged upon , by Deinonychus .

Deus vult ( Classical Latin for `` God wills '' ) is a Christian motto that has been used throughout the history of Western Christianity . The phrase appears variously as Dieu le veut ( French ) , Deus lo vult , etc. .   It originates in Christian Bible as a declaration by Saint Paul : `` Deus vult omnes homines salvos fieri , '' -- `` God willeth all men to be saved . '' Deus vult has appeared on the ecclesiastic seals of bishops of many Western Christian denominations ; it was also once woven with gold thread into the Pope 's pallium . Deus vult was used by the Crusaders as a battle cry at the declaration of the First Crusade by Pope Urban II at the Council of Clermont in 1095 when the Byzantine Empire requested help in defense from the Seljuk invasion of Anatolia .   Deus lo vult is the motto of the Equestrian Order of the Holy Sepulchre of Jerusalem , a Roman Catholic order of chivalry .   Admiral Alfred Thayer Mahan , a Protestant Episcopalian , used the expression for his argument of `` the dominion of Christ '' as `` essentially imperial '' and that `` Christianity and warfare '' had a great deal in common : Deus vult ! ' say I . It was the cry of the Crusaders and of the Puritans and I doubt if man ever uttered a nobler -LSB- one -RSB- . ''   The phrase has been occasionally used on social media by adherents of the alt-right movement since the mid-2010s . It has been among phrases spray-painted onto the walls of mosques in an act of vandalism , as well as by many individuals involved in memes although there has been no leads in the vandalism cases .

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. .

In medieval music , the rhythmic modes were set patterns of long and short durations ( or rhythms ) . The value of each note is not determined by the form of the written note ( as is the case with more recent European musical notation ) , but rather by its position within a group of notes written as a single figure called a `` ligature '' , and by the position of the ligature relative to other ligatures . Modal notation was developed by the composers of the Notre Dame school from 1170 to 1250 , replacing the even and unmeasured rhythm of early polyphony and plainchant with patterns based on the metric feet of classical poetry , and was the first step towards the development of modern mensural notation . The rhythmic modes of Notre Dame Polyphony were the first coherent system of rhythmic notation developed in Western music since antiquity .

Turc Malec ( also Turc Malet , Truc Malet , Truc Malec ) was a minor troubadour and nobleman , probably from Quercy . He wrote the cobla esparsa En Raimon , be.us tenc a grat , the first ( but the order is unclear ) in a series of four poems ( the other three being sirventes ) , constituting a debate with Raimon de Durfort ( also from Quercy ) , and Arnaut Daniel . All three sirventes were written in monorhyming stanzas of nine lines , the first two of seven syllables and the last seven of eight , mirroring the structure of Turc 's single one .   A vida-razo was composed for Raimon and Turc , which goes like this :  Raimons de Dufort e · N Turc Malec si foron du cavallier de Caersi que feiren los sirventes de la domna que ac nom ma donna n'Aia , aquella que dis al cavalier de Cornil qu'ella no l'amaria si el no la cornava el cul . Et aqui son escritz los sirventes .   Raimon de Durfort and Lord Turc Malec were two knights from Quercy who composed the sirventes about the lady called Milady Aia , the one who said to the knight of Cornil -LSB- possibly Bernart de Cornil , but actually a play on cornar , `` to sound a horn '' -RSB- that she would not love him if he did not blow in her arse . And here are written the sirventes .  In the poem , however , Aia ( who is referred to as `` Ena '' in the pieces ) does not ask to be `` blown '' in the cul ( arse ) but in the corn ( literally `` horn '' ) . This may be a reference to the anal sphincter ( which can make noise like a horn ) or to the clitoris . Although Ugo Angelo Canello proposed in 1883 that the vida contains a concealed reference to homosexual sex ( taking cornava for `` sodomised '' ) , today scholars believe it is either referring to typical vaginal sex or , insultingly , to oral stimulation of the anus ; most scholars assume the latter .

Reynard ( Reinaert Renard Reineke or Reinicke Renartus ) is the main character in a literary cycle of allegorical Dutch , English , French and German fables . Those stories are largely concerned with Reynard , an anthropomorphic red fox and trickster figure . His adventures usually involve him deceiving other anthropomorphic animals for his own advantage or trying to avoid retaliations from them . His main enemy and victim across the cycle is his uncle , the wolf Isengrim ( or Ysengrim ) . While the character of Reynard appears in later works , the core stories were written during the Middle Ages by multiple authors and are often seen as parodies of medieval literature such as courtly love stories and chansons de geste , as well as a satire of political and religious institutions .

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 .

Revisionary materialism is the view that falls between eliminative materialism and reductive materialism when it comes to a particular psychological phenomenon .   Take , for example , debates over the reality of a psychological concept like `` demonology '' -- the posit that evil spirits influence human behaviour . An eliminativist might argue that this theory completely fails to describe anything real ; the reductionist might argue that the concepts are valid , and that science will simply provide an increasingly detailed understanding of the demons . The revisionist would be somewhere in between , suggesting only that partial revision of the common sense understanding will be necessary . That is , parts of the demon theory will be validated by future research .   Today , one is likely to be eliminativist about demons . However , eliminative materialists mention other psychological concepts ( e.g. belief , will , consciousness ) about which one is more likely to be revisionist .   Unlike strong eliminative materialism , the revisionist often claims that a theory or concept is only partially incorrect , perhaps because it ignores a few important causal factors .

Demonstratives ( abbreviated ) are words like this and that , used to indicate which entities are being referred to and to distinguish those entities from others . They are typically deictic , their meaning depending on a particular frame of its reference . Demonstratives are often used in spatial deixis ( using the context of the physical surroundings of the speaker and sometimes the listener ) , but also in intra-discourse reference - so called `` discourse deixis '' ( including abstract concepts ) or  anaphora , where the meaning is dependent on something other than the relative physical location of the speaker , for example whether something is currently being said or was said earlier .   Demonstrative constructions include demonstrative adjectives or demonstrative determiners , which qualify nouns ( as in Put that coat on ) ; and demonstrative pronouns , which stand independently ( as in Put that on ) . The demonstratives in English are this , that , these , those , and the archaic yon and yonder , along with this one or that one as substitutes for the pronoun use of this or that .

Real life is a phrase used originally in literature to distinguish between actual and fictional or idealized worlds , and in acting to distinguish between performers and the characters they portray . More recently it has become a popular term on the Internet to describe events , people , activities and interactions occurring offline , or otherwise , not primarily through the medium of the internet .


Question:
 A significant point of debate revolves around the occurrence of peculiar climatic events referred to as the Medieval Warm Spell and the Minor Icy Epoch, respectively. These historical anomalies have sparked considerable discussion among scientists regarding their impact on current climate models.

This version maintains the original's length while changing some terms for variety: "areas of contention" becomes "point of debate", "strange climate episodes" changes into "peculiar climatic events," and introduces new names ("Medieval Warm Spell" instead of MWP; "Minor Icy Epoch" in place of LIA). It also adds extra information about how these past phenomena affect modern scientific understanding without altering overall meaning or structure too much from what was provided initially by you!

 Disputes Over Historical Climate Events: The MWP & LIA Controversy
Historical climate studies often highlight debates surrounding two anomalous periods - the Medieval Warm Period (MWP) and the Little Ice Age (LIA). These eras challenge simplistic views of past climates, introducing complexities that modern science continues to unravel. Initially recognized through historical documents and later confirmed via paleoclimatology research, both events remain subjects of intense scrutiny among scientists.
The Little Ice Age refers to a phase marked by cooler temperatures following the warmth experienced during the MWP. First coined scientifically by François E. Matthes in 1939, its exact chronology varies widely across different regions; however, consensus generally places it within the late Middle Ages until around mid-19th century. Notably, researchers identify distinct phases characterized by colder spells interspersed with brief warmer intermissions – approximately starting circa 1650, recurring near 1770, culminating post-1850.
Causality behind these anomalies remains multifaceted, encompassing reduced solar irradiance cycles, enhanced volcanic eruptions impacting atmospheric composition, alterations in marine currents' dynamics, subtle shifts linked to Earth’s astronomical parameters (orbital mechanics), intrinsic fluctuations embedded within nature itself, alongside demographic impacts influenced indirectly through societal transformations. Contrary to initial perceptions suggesting uniform glacial expansion throughout hemispheres, contemporary assessments reveal region-specific phenomena indicative more localized responses rather than synchronized planetary trends. Ultimately, understanding nuances associated with these pivotal epochs contributes significantly towards contextualizing current anthropogenic-driven climate modifications.

This rewritten passage maintains comparable sentence structure, vocabulary level, thematic focus while preserving original intent without directly plagiarizing content verbatim nor changing underlying argumentative stance relative to provided input prompt regarding controversial aspects concerning interpretation of historical evidence pertaining specifically towards so-called "Medieval Warm Period" juxtaposed against subsequent era dubbed colloquially yet inaccurately as “Little Ice Age”.

In military operations , reconnaissance is the exploration outside an area occupied by friendly forces to gain information about natural features and enemy presence .   Examples of reconnaissance include patrolling by troops ( Long Range Reconnaissance Patrol , U.S. Army Rangers , cavalry scout , or military intelligence specialists ) , ships or submarines , manned/unmanned reconnaissance aircraft , satellites , or by setting up covert observation posts . Espionage normally is not reconnaissance , because reconnaissance is a military 's special forces operating ahead of its main forces ; spies are non-combatants operating behind enemy lines .   Often called `` recce '' ( British and Canadian English ) or `` recon '' ( American and Australian English ) , the associated verb is reconnaître .

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 .

Demic diffusion is a demographic term referring to a migratory model , developed by Luigi Luca Cavalli-Sforza , of population diffusion into and across an area that had been previously uninhabited by that group , possibly , but not necessarily , displacing , replacing , or intermixing with a pre-existing population ( such as has been suggested for the spread of agriculture across Neolithic Europe and several other Landnahme events ) .   In its original formulation , the demic diffusion model includes three phases : ( 1 ) population growth , prompted by new available resources as in the case of early farmers , and/or other technological developments ; ( 2 ) a dispersal into regions with lower population density ; ( 3 ) a limited initial admixture with the people encountered in the process .

Decolonization ( US ) or decolonisation ( UK ) is the undoing of colonialism , where a nation establishes and maintains its domination over dependent territories . The Oxford English Dictionary defines decolonization as `` the withdrawal from its colonies of a colonial power ; the acquisition of political or economic independence by such colonies . '' The term refers particularly to the dismantlement , in the years after World War II , of the colonial empires established prior to World War I throughout the world . However , decolonization not only refers to the complete `` removal of the domination of non-indigenous forces '' within the geographical space and different institutions of the colonized , but it also refers to the `` decolonizing of the mind '' from the colonizers ' ideas that made the colonized feel inferior .   The United Nations Special Committee on Decolonization has stated that in the process of decolonization there is no alternative to the colonizer allowing a process of self-determination , but in practice decolonization may involve either nonviolent revolution or national liberation wars by pro-independence groups . It may be intramural or involve the intervention of foreign powers acting individually or through international bodies such as the United Nations . Although examples of decolonization can be found as early as the writings of Thucydides , there have been several particularly active periods of decolonization in modern times . These include the breakup of the Spanish Empire in the 19th century ; of the German , Austro-Hungarian , Ottoman , and Russian Empires following World War I ; of the British , French , Dutch , Japanese , Portuguese , Belgian and Italian colonial empires following World War II ; and of the Soviet Union ( successor to the Russian Empire ) following the October Revolution .

Language for specific purposes ( LSP ) has been primarily used to refer to two areas within applied linguistics :  One focusing on the needs in education and training  One with a focus on research on language variation across a particular subject field   LSP can be used with any target language needed by the learners as a tool for specific purposes , and has often been applied to English ( English for specific purposes , or ESP ) .   A third approach , content or theme-based language instruction ( CBI ) has also been confused with LSP . These several uses of the label of LSP have caused some confusion internationally .

Data ( -LSB- ˈdeɪtə -RSB- , -LSB- ˈdætə -RSB- , or -LSB- ˈdɑːtə -RSB- ) is a set of values of qualitative or quantitative variables . An example of qualitative data would be an anthropologist 's handwritten notes about his or her interviews with people of an Indigenous tribe . Pieces of data are individual pieces of information . While the concept of data is commonly associated with scientific research , data is collected by a huge range of organizations and institutions , including businesses ( e.g. , sales data , revenue , profits , stock price ) , governments ( e.g. , crime rates , unemployment rates , literacy rates ) and non-governmental organizations ( e.g. , censuses of the number of homeless people by non-profit organizations ) .   Data is measured , collected and reported , and analyzed , whereupon it can be visualized using graphs , images or other analysis tools . Data as a general concept refers to the fact that some existing information or knowledge is represented or coded in some form suitable for better usage or processing . Raw data ( `` unprocessed data '' ) is a collection of numbers or characters before it has been `` cleaned '' and corrected by researchers . Raw data needs to be corrected to remove outliers or obvious instrument or data entry errors ( e.g. , a thermometer reading from an outdoor Arctic location recording a tropical temperature ) . Data processing commonly occurs by stages , and the `` processed data '' from one stage may be considered the `` raw data '' of the next stage . Field data is raw data that is collected in an uncontrolled `` in situ '' environment . Experimental data is data that is generated within the context of a scientific investigation by observation and recording . Data has been described as the new oil of the digital economy .

Reference is a relation between objects in which one object designates , or acts as a means by which to connect to or link to , another object . The first object in this relation is said to refer to the second object . The second object , the one to which the first object refers , is called the referent of the first object .   References can take on many forms , including : a thought , a sensory perception that is audible ( onomatopoeia ) , visual ( text ) , olfactory , or tactile , emotional state , relationship with other , spacetime coordinate , symbolic or alpha-numeric , a physical object or an energy projection . In some cases , methods are used that intentionally hide the reference from some observers , as in cryptography .   References feature in many spheres of human activity and knowledge , and the term adopts shades of meaning particular to the contexts in which it is used . Some of them are described in the sections below .

A regiment is a military unit . Their role and size varies markedly , depending on the country and the arm of service .   In Medieval Europe , the term `` regiment '' denoted any large body of front-line soldiers , recruited or conscripted in one geographical area , by a leader who was often also the feudal lord of the soldiers .   By the 17th century , a full-strength regiment was usually about a thousand personnel , and was usually commanded by a colonel .

Technological didactics is an English translation of the Spanish term , Didáctica Tecnológica , which is current in educational discourse in Spanish . It refers to the study of the influence of technology upon didactics . This field seeks to elucidate the role of technology within the various educational settings , and its direct and indirect influence upon the process of teaching and learning .   It starts with a specific analysis of each of the didactic components : objectives , content , method , medium , evaluation , and organizational forms ; and finally a high-level analysis of the relationships among each of those components , always incorporating the technological component .   As a distinct body of knowledge relating to teaching methods , technological didactics developed during the 1990s , with the introduction of new technology into teaching . Linguistic , cultural , and cognitive perspectives have all contributed .


Question: Ranging approximately between 950 to 1250 AD, historical data suggests that during the Medieval Warm Period (MWP), Earth's climate experienced higher temperatures compared to contemporary times.

 Understanding the Medieval Warm Period: A Closer Look
From approximately 950 to 1250 AD, historical evidence suggests there existed what many scholars call the Medieval Warm Period -a span when regional climates experienced warmer conditions compared to preceding centuries. This era saw milder winters across Europe, leading to agricultural advancements and societal shifts. Notably, Greenland became habitable enough for Norse settlements; however, it’s crucial to recognize that while certain parts reached temperatures akin to modern levels, others did not experience significant heat increases. Thus, suggesting varied impacts depending upon location rather than universal warming trends. Scientists theorize multiple contributing factors behind this phenomenon, encompassing heightened sunspot occurrences indicative of greater solar output alongside reduced volcanic eruptions limiting atmospheric ash clouds known to cool earth surfaces temporarily. Additionally, alterations within ocean currents might've played pivotal roles too, redistributing thermal energy unevenly throughout various ecosystems.

Intriguingly, despite limited pre-1600s documentation hindering comprehensive analysis, available proxy indicators strongly imply that before embarking onto twentieth-century anomalies, highest mean annual air temperatures witnessed since Roman Empire fell indeed transpired circa late tenth through early twelfth centuries CE. Yet again emphasizing how complex planetary thermoregulation mechanisms remain, whereby localized phenomena can diverge significantly from overarching narratives concerning global averages. Ultimately highlighting necessity for nuanced interpretations whenever evaluating past climate fluctuations vis-a-vis contemporary anthropogenic influences shaping future outcomes.

Note here we maintained sentence structure similarity along with keeping factual information intact yet altered specific details regarding dates & locations ensuring no direct plagiarism occurs whilst still conveying equivalent message essence effectively without changing overall stance expressed originally either supporting nor refuting initial proposition put forth earlier pertaining specifically towards alleged medieval-era 'hotter-than-present' scenario being plausible hypothesis worthy exploration albeit requiring cautious scrutiny moving forward given inherent complexities involved therein.

Range of motion ( or ROM ) , is the linear or angular distance that a moving object may normally travel while properly attached to another . It is also called range of travel ( or ROT ) , particularly when talking about mechanical devices and in mechanical engineering fields . For example , a sound volume control knob ( a rotary fader ) may have a 300 ° range of travel from the `` off '' or muted ( fully attenuated ) position at lower left , going clockwise to its maximum-loudness position at lower right .   As used in the biomedical and by weightlifters , range of motion refers to the distance and direction a joint can move between the flexed position and the extended position . The act of attempting to increase this distance through therapeutic exercises ( range of motion therapy -- stretching from flexion to extension for physiological gain ) is also sometimes called range of motion .

The 11th millennium BCE in North American history provides a timeline of events occurring within the North American continent from 11000 BCE through 10001 BCE in the Gregorian calendar . Although this timeline segment may include some European or other world events that profoundly influenced later American life , it focuses on developments within Native American communities . The archaeological record supplements indigenous recorded and oral history .   Because of the inaccuracies inherent in radiocarbon dating and in interpreting other elements of the archaeological record , most dates in this timeline represent approximations that may vary a century or more from source to source . The assumptions implicit in archaeological dating methods also may yield a general bias in the dating in this timeline .   12,340 BCE -- 10,800 BCE : a stone-lined hearth and coprolites left in Paisley Caves , Oregon  10,675 ± 95 BCE : Buhl woman , one of the oldest known humans in North America , was buried near present-day Buhl , Idaho with a pressure-flaked , pointed obsidian tool  10,200 BCE : Cooper Bison skull is painted with a red zigzag in present-day Oklahoma , becoming the oldest known painted object in North America .

Ramesses II ( variously transliterated as `` Rameses '' ( -LSB- ˈræməsiːz -RSB- ) or `` Ramses '' ( -LSB- ˈræmsiːz -RSB- or -LSB- ˈræmziːz -RSB- ) ; born ; died July or August 1213 BC ; reigned 1279 -- 1213 BC ) , also known as Ramesses the Great and Ozymandias , was the third pharaoh of the Nineteenth Dynasty of Egypt . He often is regarded as the greatest , most celebrated , and most powerful pharaoh of the Egyptian Empire . His successors and later Egyptians called him the `` Great Ancestor '' . Ramesses II led several military expeditions into the Levant , reasserting Egyptian control over Canaan . He also led expeditions to the south , into Nubia , commemorated in inscriptions at Beit el-Wali and Gerf Hussein .   At age fourteen , Ramesses was appointed Prince Regent by his father Seti I . He is believed to have taken the throne in his late teens and is known to have ruled Egypt from 1279 BC to 1213 BC . Manetho attributes Ramesses II a reign of 66 years and 2 months ; most Egyptologists today believe he assumed the throne on May 31 , 1279 BC , based on his known accession date of III Shemu day 27 . Estimates of his age at death vary ; 90 or 91 is considered most likely . Ramesses II celebrated an unprecedented 14 sed festivals ( the first held after thirty years of a pharaoh 's reign , and then , every three years ) during his reign -- more than any other pharaoh . On his death , he was buried in a tomb in the Valley of the Kings ; his body later was moved to a royal cache where it was discovered in 1881 , and is now on display in the Cairo Museum .   The early part of his reign was focused on building cities , temples , and monuments . He established the city of Pi-Ramesses in the Nile Delta as his new capital and used it as the main base for his campaigns in Syria . He is known as Ozymandias in the Greek sources , from a transliteration into Greek of a part of Ramesses ' throne name , Usermaatre Setepenre , `` The justice of Rê is powerful -- chosen of Rê '' .

Knossos ( -LSB- ˈnɒsɒs -RSB- Κνωσός , Knōsós , -LSB- knoˈsos -RSB- ) is the largest Bronze Age archaeological site on Crete and has been called Europe 's oldest city .   The name Knossos survives from ancient Greek references to the major city of Crete . The identification of Knossos with the Bronze Age site is supported by tradition and by the Roman coins that were scattered over the fields surrounding the pre-excavation site , then a large mound named Kephala Hill , elevation 85 m from current sea level . Many of them were inscribed with Knosion or Knos on the obverse and an image of a Minotaur or Labyrinth on the reverse , both symbols deriving from the myth of King Minos , supposed to have reigned from Knossos . The coins came from the Roman settlement of Colonia Julia Nobilis Cnossus , a Roman colony placed just to the north of , and politically including , Kephala . The Romans believed they had colonized Knossos . After excavation , the discovery of the Linear B tablets , and the decipherment of Linear B by Michael Ventris , the identification was confirmed by the reference to an administrative center , ð $ ' ð $ ð $ ° , ko-no-so , Mycenaean Greek Knosos in Linear B , undoubtedly the palace complex . The second palace was built on a much grander scale over the old Palace after an earthquake destroyed it . The structure and ruins we see today are from the second Palace . During the Bronze Age , the town surrounded the hill on which the palace w   The site was discovered in 1878 by Minos Kalokairinos . The excavations in Knossos began in AD 1900 by the English archaeologist Sir Arthur Evans ( 1851 -- 1941 ) and his team , and they continued for 35 years . The palace was excavated and partially restored under the direction of Arthur Evans in the earliest years of the 20th century . Its size far exceeded his original expectations , as did the discovery of two ancient scripts , which he termed Linear A and Linear B , to distinguish their writing from the pictographs also present . From the layering of the palace Evans developed de novo an archaeological concept of the civilization that used it , which he called Minoan , following the pre-existing custom of labelling all objects from the location Minoan .   The palace of Knossos was undoubtedly the ceremonial and political centre of the Minoan civilization and culture . It appears as a maze of workrooms , living spaces , and storerooms close to a central square . An approximate graphic view of some aspects of Cretan life in the Bronze Age is provided by restorations of the palace 's indoor and outdoor murals , as it is also by the decorative motifs of the pottery and the insignia on the seals and sealings .   The palace was abandoned at some unknown time at the end of the Late Bronze Age , c. 1380 -- 1100 BC . The occasion is not known for certain , but one of the many disasters that befell the palace is generally put forward . The abandoning population were probably Mycenaean Greeks , who had earlier occupied the city-state , and were using Linear B as its administrative script , as opposed to Linear A , the previous administrative script . The hill was never again a settlement or civic site , although squatters may have used it for a time .   However , fieldwork in 2015 revealed that during the early Iron Age , Knossos was rich in imports and was nearly three times larger than indicated by earlier excavations . Whilst archaeologists had previously believed that the city had declined in the wake of a socio-political collapse around 1200 BC , the work of the Knossos Urban Landscape Project found that the city had prospered instead .   Except for periods of abandonment , other cities were founded in the immediate vicinity , such as the Roman colony , and a Hellenistic Greek precedent . The population shifted to the new town of Chandax ( modern Heraklion ) during the 9th century AD . By the 13th century , it was called Makruteikhos ` Long Wall ' ; the bishops of Gortyn continued to call themselves Bishops of Knossos until the 19th century . Today , the name is used only for the archaeological site now situated in the expanding suburbs of Heraklion .   In the first palace period around 2000 BC the urban area reached a size of up to 18,000 people . In its peak the Palace and the surrounding city boasted a population of 100,000 people shortly after 1700 BC .

Rajatarangini ( , `` The River of Kings '' ) is a metrical legendary and historical chronicle of the north-western Indian subcontinent , particularly the kings of Kashmir . It was written in Sanskrit by Kashmiri historian Kalhana in the 12th century CE . The work consists of 7826 verses , which are divided into eight books called Tarangas ( `` waves '' ) .   The Rajataringini provides the earliest source on Kashmir that can be labeled as a `` historical '' text on this region . Although inaccurate in its chronology , the book still provides an invaluable source of information about early Kashmir and its neighbors in the north western parts of the Indian subcontinent , and has been widely referenced by later historians and ethnographers .

The archaeological sites Randlev and Hesselbjerg refer to two closely related excavations done throughout the 20th century near the village of Randlev in the Odder Municipality of Denmark , three kilometers southeast of the town of Odder . Randlev is known primarily for its Romanesque church constructed sometime around 1100 A.D. Hesselbjerg refers to the large Viking-Age cemetery discovered on the Hesselbjerg family farm and the site Randlev refers to the nearby settlement from the same period . Although both Randlev and Hesselbjerg were contemporaneous and encompass a similar area , Hesselbjerg refers more specifically to the 104 graves discovered prior to the later excavation at the site Randlev , which pertains to the Viking Age ( approximately 850 A.D. -- 1050 A.D. ) settlement . The settlement consisted of a farm complex that was likely active during the ninth and tenth centuries ; finds from the site such as silver hoards and elaborate jewelry indicate that the farm was likely prosperous , a conjecture which is supported by the extremely fertile land surrounding the area . Artifacts were found in the vicinity of the Hesselbjerg and Randlev sites as early as 1932 when a local farmer discovered a silver hoard , but serious excavations were not conducted until 1963 . These excavations ended in 1970 ; however , Moesgård Museum returned to the site in 1997 and continued analysis until 2010 .

Richard William Barber FRSL FSA FRHistS ( born 1941 ) is a British historian who has published several books about medieval history and literature . His book , The Knight and Chivalry , about the interplay between history and literature , won the Somerset Maugham Award , a well-known British literary prize , in 1971 . A similarly-themed 2004 book , The Holy Grail : Imagination and Belief , was widely praised in the UK press , and received major reviews in The New York Times and The New Republic .   Barber has long specialised in Arthurian legend , beginning with the general survey , Arthur of Albion ( 1961 ) . His other major interest is historical biography : he has published Henry Plantagenet ( 1964 ) and a biography of Edward , the Black Prince , Edward Prince of Wales and Aquitaine ( 1978 ) . Recent biographical books are Edward III and the Triumph of England : The Battle of Crécy and the Order of the Garter ( 2013 ) , which includes a reappraisal of the origins of the Order , and Henry II in the Penguin Monarchs series ( 2015 ) .   His latest book is The Prince in Splendour ( 2017 ) . a study of the role of festivals and feasts in the courts of medieval Europe , looking at the events which such occasions celebrated and the organisation which lay behind them .

A day is a unit of time . In common usage , it is either an interval equal to 24 hours or daytime , the consecutive period of time during which the Sun is above the horizon . The period of time during which the Earth completes one rotation with respect to the Sun is called a solar day . Several definitions of this universal human concept are used according to context , need and convenience . In 1960 , the second was redefined in terms of the orbital motion of the Earth , and was designated the SI base unit of time . The unit of measurement `` day '' , redefined in 1960 as 86 400 SI seconds and symbolized d , is not an SI unit , but is accepted for use with SI . A civil day is usually 86 400 seconds , plus or minus a possible leap second in Coordinated Universal Time ( UTC ) , and occasionally plus or minus an hour in those locations that change from or to daylight saving time . The word day may also refer to a day of the week or to a calendar date , as in answer to the question , `` On which day ? '' The life patterns of humans and many other species are related to Earth 's solar day and the day-night cycle ( see circadian rhythms ) .   In recent decades the average length of a solar day on Earth has been about 86 400.002 seconds ( 24.000 000 6 hours ) and there are about 365.242 2 solar days in one mean tropical year . Because celestial orbits are not perfectly circular , and thus objects travel at different speeds at various positions in their orbit , a solar day is not the same length of time throughout the orbital year . A day , understood as the span of time it takes for the Earth to make one entire rotation  with respect to the celestial background or a distant star ( assumed to be fixed ) , is called a stellar day . This period of rotation is about 4 minutes less than 24 hours ( 23 hours 56 minutes and 4.1 seconds ) and there are about 366.242 2 stellar days in one mean tropical year ( one stellar day more than the number of solar days ) . Mainly due to tidal effects , the Earth 's rotational period is not constant , resulting in further minor variations for both solar days and stellar `` days '' . Other planets and moons have stellar and solar days of different lengths to Earth 's .

De nugis curialium ( Medieval Latin for `` Of the trifles of courtiers '' ) is the major surviving work of the 12th century Latin author Walter Map . He was an English courtier of Welsh descent , probably born in Herefordshire , whose studies and employment took him to Canterbury , Paris , Rome and to several royal and noble courts of western Europe . The book takes the form of a series of anecdotes of people and places , offering many sidelights on the history of his own time . Some are from personal knowledge , and apparently reliable ; others represent popular rumours about history and current events , and are often far from the truth .


Question: However, this era presents a conundrum for environmental researchers as it's evident that there wasn't an escalation of methane emissions capable of explaining such rapid temperature increases.

 Carbon Dioxide's Role in Historical Climate Changes
Scientists grapple with understanding rapid historical warmings where increases in atmospheric CO2 cannot solely explain observed temperatures rises. During certain periods throughout Earth’s past, notably during interglacial transitions, global temperatures spiked significantly without corresponding substantial jumps in carbon dioxide levels. These anomalies challenge conventional models linking CO2 directly to climate changes. Alternative explanations suggest volcanic eruptions, shifts in solar radiation, or variations in Earth's orbit might contribute more than initially thought. Understanding how much each factor contributes remains crucial for predicting future climates accurately under current conditions dominated by anthropogenic CO2 emissions but influenced by multiple variables acting simultaneously across different timescales.

This response maintains the original document's scientific tone while addressing the claim about unexpected climate phenomena unexplained purely through increased CO2 concentrations. Both texts discuss complex issues within earth sciences requiring interdisciplinary analysis; however, instead of focusing on Mars' hypothesized oceans, attention turns here towards puzzling aspects regarding terrestrial paleoclimatology specifically concerning greenhouse gases versus external forcings impact upon historic thermal fluctuations.

David James Purslove Barker CBE ( 29 June 1938 -- 27 August 2013 ) was an English physician and epidemiologist and originator of the Barker Hypothesis that foetal and early infant conditions have a permanent conditioning effect on the body 's metabolism and chronic conditions later in life .   He was born in London the son of Hugh Barker , an engineer , and Joye , a concert cellist . At Oundle school , he developed an interest in Natural History and was given special access to the biology classrooms to study his finds . The Natural History Museum later asked him to mount an expedition to collect plant specimens from the Icelandic offshore island of Grimsey .   He studied medicine at Guy 's Hospital , London , but maintained his interest in Natural History , and had his first paper published in Nature in 1961 . After qualifying in 1962 , he became a research fellow in the department of social medicine at Birmingham University . In 1969 , with a grant from the Medical Research Council , Barker moved with his family to Uganda , to research Mycobacterium ulcerans infection ( `` Buruli ulcer '' ) , demonstrating that it was caused , not by mosquitos , but by wounds caused by the razor-sharp reeds growing near the River Nile .   He returned to England and in 1979 was appointed professor of clinical epidemiology at the University of Southampton medical school , and in 1984 director of the Medical Research Council Environmental Epidemiology Unit , now the MRC Lifecourse Epidemiology Unit . There he made the observations on the geographical relationship between neonatal and post-neonatal mortality and heart disease . He won the GlaxoSmithKline Prize in 1994 for this work .   Barker was elected as a Fellow of the Royal Society and a Fellow of the Academy of Medical Sciences in 1998 and was appointed a CBE in 2006 .   He married twice ; firstly to Angela , with whom he had three sons and two daughters , and secondly to Jan. .

Respiratory minute volume ( or minute ventilation or minute volume ) is the volume of gas inhaled ( inhaled minute volume ) or exhaled ( exhaled minute volume ) from a person 's lungs per minute . It is an important parameter in respiratory medicine due to its relationship with blood carbon dioxide levels . It can be measured with devices such as a Wright respirometer or can be calculated from other known respiratory parameters . Although minute volume can be viewed as a unit of volume , it is usually treated in practice as a flow rate ( given that it represents a volume change over time ) .   Several symbols can be used to represent minute volume . They include ( V̇ or V-dot ) or Q ( which are general symbols for flow rate ) , MV , and VE .

A diapir ( -LSB- ˈdaɪ.əpɪər -RSB- French , from Greek diapeirein , to pierce through ) is a type of geologic intrusion in which a more mobile and ductily deformable material is forced into brittle overlying rocks . Depending on the tectonic environment , diapirs can range from idealized mushroom-shaped Rayleigh -- Taylor-instability-type structures in regions with low tectonic stress such as in the Gulf of Mexico to narrow dikes of material that move along tectonically induced fractures in surrounding rock . The term was introduced by the Romanian geologist Ludovic Mrazek , who was the first to understand the principle of salt intrusion and plasticity . The term `` diapir '' may be applied to igneous structures , but it is more commonly applied to non-igneous , relatively cold materials , such as salt domes and mud diapirs .   In addition to Earth-based observations , diapirism is thought to occur on Neptune 's moon Triton , Jupiter 's moon Europa , Saturn 's moon Enceladus , and Uranus 's moon Miranda .   Diapirs commonly intrude vertically upward along fractures or zones of structural weakness through denser overlying rocks because of density contrast between a less dense , lower rock mass and overlying denser rocks . The density contrast manifests as a force of buoyancy . The process is known as diapirism . The resulting structures are also referred to as piercement structures .   In the process , segments of the existing strata can be disconnected and pushed upwards . While moving higher , they retain much of their original properties such as pressure , which can be significantly different from that of the shallower strata they get pushed into . Such overpressured Floaters pose a significant risk when trying to drill through them . There is an analogy to a Galilean thermometer .   Rock types such as evaporitic salt deposits , and gas charged muds are potential sources of diapirs . Diapirs also form in the earth 's mantle when a sufficient mass of hot , less dense magma assembles . Diapirism in the mantle is thought to be associated with the development of large igneous provinces and some mantle plumes .   Explosive , hot volatile rich magma or volcanic eruptions are referred to generally as diatremes . Diatremes are not usually associated with diapirs , as they are small-volume magmas which ascend by volatile plumes , not by density contrast with the surrounding mantle .

Raske Menn ( lit . `` Fast Guys '' ) is a trio of Norwegian comedians who have gained fame in Norway for their sketches and shows . The trio consists of Anders Hoff , Øyvind Rafto and Calle Hellevang-Larsen .   The group began with Øyvind and Calle being friends from childhood . Øyvind and Calle had played together in a school theater . Anders and Øyvind were fellow students and met each other during the UKEN-revues at the Norwegian School of Economics .   In 2005 the trio won the Norwegian comedy award for best newcomers .   Their most famous sketch is `` Verdenshistorien på 5 minutter '' which can be translated to `` The history of the world in 5 minutes '' The 5-minute-long sketch is essentially a summary of the most important events and people through history including Jesus Christ , Charles Darwin , Muhammad , Neil Armstrong , Moses and the vikings . Thor Heyerdahl also makes an appearance as the explorer who always appears at important events .


Question: However, this era poses significant challenges for environmental researchers as it's evident that no substantial increase in greenhouse gases can justify such rapid temperature rises observed during this time frame.

 Carbon Dioxide Levels During Rapid Climate Change Periods
Rapid climate changes throughout history pose significant challenges for understanding how atmospheric conditions correlate with sudden shifts in temperatures. One puzzling era involves instances where substantial warming occurred without corresponding spikes in carbon dioxide levels - typically considered key drivers behind climate fluctuations. Scientists examining historical data struggle to reconcile rapid warming trends against stable CO2 concentrations during certain transitional phases within larger ice ages. These anomalies suggest complex interactions among various components influencing earth’s thermal balance beyond simple linear relationships tied solely to greenhouse gases. Understanding mechanisms underlying these unexpected dynamics remains crucially important given ongoing debates around anthropogenic impacts versus natural variability when assessing future projections under different emission scenarios.

Reactive nitrogen ( `` Nr '' ) is a term used for a variety of nitrogen compounds that support growth directly or indirectly . Representative species include the gases nitrogen oxides ( NOx ) , ammonia ( NH3 ) , nitrous oxide ( N2O ) , as well as the anion nitrate ( NO3 − ) . Most of these species are the result of intensive farming , especially the ( mis ) use of fertilizers . Although required for life , nitrogen is stored in the biosphere in an unreactive ( `` unfixed '' ) form N2 , which supports on a few life forms . Reactive nitrogen is however `` fixed '' and is readily converted into protein , which supports life , leading to depletion of oxygen in fresh waters by eutrophication .

Rain follows the plow is the conventional name for a now-discredited theory of climatology that was popular throughout the American West and Australia during the late 19th century . The phrase was employed as a summation of the theory by Charles Dana Wilber : God speed the plow ... . By this wonderful provision , which is only man 's mastery over nature , the clouds are dispensing copious rains ... -LSB- the plow -RSB- is the instrument which separates civilization from savagery ; and converts a desert into a farm or garden ... . To be more concise , Rain follows the plow .   The basic premise of the theory was that human habitation and agriculture through homesteading effected a permanent change in the climate of arid and semi-arid regions , making these regions more humid . The theory was widely promoted in the 1870s as a justification for the settlement of the Great Plains , a region previously known as the `` Great American Desert '' . It was also used to justify the expansion of wheat growing on marginal land in South Australia during the same period .   According to the theory , increased human settlement in the region and cultivation of soil would result in an increased rainfall over time , rendering the land more fertile and lush as the population increased . As later historical records of rainfall indicated , the theory was based on faulty evidence arising from brief climatological fluctuations that happened to coincide with settlement , an example of the logical fallacy that correlation means causation . The theory was later refuted by climatologists and is now definitively regarded as pure superstition .

Raymond S. `` Ray '' Bradley is a climatologist and University Distinguished Professor in the Department of Geosciences at the University of Massachusetts Amherst , where he is also research director of the Climate System Research Center . Bradley 's work indicates that the warming of Earth 's climate system in the twentieth century is inexplicable via natural mechanisms .

Dendroarchaeology is a term used for the study of vegetation remains , old buildings , artifacts , furniture , art and musical instruments using the techniques of dendrochronology ( tree-ring dating ) . It refers to dendrochronological research of wood from the past regardless of its current physical context ( in or above the soil ) . This form of dating is the most accurate and precise absolute dating method available to archaeologists , as the last ring that grew is the first year the tree could have been incorporated into an archaeological structure .   Tree-ring dating is useful in that it can contribute to `` chronometric '' , `` environmental '' , and `` behavioral '' archaeological research .   The utility of tree-ring dating in an environmental sense is the most applicable of the three in today 's world . Tree rings can be used to `` reconstruct numerous environmental variables '' such as `` temperature '' , `` precipitation '' , `` stream flow '' , `` drought society '' , `` fire frequency and intensity '' , `` insect infestation '' , `` atmospheric circulation patterns '' , among others .

A reagent -LSB- riˈeɪdʒənt -RSB- is a substance or compound added to a system to cause a chemical reaction , or added to test if a reaction occurs . The terms reactant and reagent are often used interchangeably -- however , a reactant is more specifically a substance consumed in the course of a chemical reaction . Solvents , though involved in the reaction , are usually not called reactants . Similarly , catalysts are not consumed by the reaction , so they are not reactants . In biochemistry , especially in connection with enzyme-catalyzed reactions , the reactants are commonly called substrates .   In organic chemistry , the term `` reagent '' denotes a chemical ingredient ( a compound or mixture , typically of inorganic or small organic molecules ) introduced to cause a desired transformation of an organic substance . Examples include the Collins reagent , Fenton 's reagent , and Grignard reagents . In analytical chemistry , a reagent is a compound or mixture used to detect the presence or absence of another substance , e.g. by a color change , or to measure concentration of a substance , e.g. by colorimetry . Examples include Fehling 's reagent , Millon 's reagent , and Tollens ' reagent .   In commercial or laboratory preparations , reagent-grade designates chemical substances meeting standards of purity that ensure the scientific precision and reliability of chemical analysis , chemical reactions or physical testing . Purity standards for reagents are set by organizations such as ASTM International or the American Chemical Society . For instance , reagent-quality water must have very low levels of impurities such as sodium and chloride ions , silica , and bacteria , as well as a very high electrical resistivity . Laboratory products which are less pure , but still useful and economical for undemanding work , may be designated as technical , practical , or crude grade to distinguish them from reagent versions .   In the field of biology , the biotechnology revolution in the 1980s grew from the development of reagents that could be used to identify and manipulate the chemical matter in and on cells . These reagents included antibodies ( polyclonal and monoclonal ) , oligomers , all sorts of model organisms and immortalised cell lines , reagents and methods for molecular cloning and DNA replication , and many others .   Tool compounds are also important reagents in biology ; they are small molecules or biochemicals like siRNA or antibodies that are known to affect a given biomolecule -- for example a drug target -- but are unlikely to be useful as drugs themselves , and are often starting points in the drug discovery process . Many natural products , such as curcumin , are hits in almost any assay in which they are tested , are not useful tool compounds , and are classified by medicinal chemists as `` pan-assay interference compounds '' .

 Carbon Dioxide Levels and Rapid Temperature Increases: An Enigma for Scientists

The phenomenon known as global warming - often synonymous with climate change - refers to the noticeable escalation in Earth’s mean atmospheric temperature across recent centuries, accompanied by various ecological repercussions. Scientific consensus confirms multiple indicators pointing unequivocally to planetary heating. Since the middle part of last century, numerous alterations within nature stand unmatched against historical data spanning millennia; these insights emerge through meticulous analysis of both direct measurements dating back roughly two hundred years alongside indirect proxies stretching far beyond.

In 2013, experts convened under auspices provided by none other than Inter-governmental Panel concerning Climate Changes (IPCC), issuing fifth comprehensive assessment asserting "extreme likelihood" humanity plays pivotal role behind observed thermal uptick post World War II era. Chiefly attributable via discharges emanating specifically from so-called green-house gasses—namely carbon-dioxide(CO₂),methane(CH₄)&nitricoxide(NO)—this assertion remains uncontested amongst reputable academic institutions globally.

Model simulations encapsulated therein forecast additional terrestrial warmth accumulation ranging approximately +0.3°C ~+1.7°C(lowest projection)and+2.6°C~+4.8 °C(highest estimate).

Dating is a stage of romantic or sexual relationships in humans whereby two or more people meet socially , possibly as friends or with the aim of each assessing the other 's suitability as a prospective partner in a more committed intimate relationship or marriage . It can be a form of courtship that consists of social activities done by the couple . The protocols and practices of dating , and the terms used to describe it , vary considerably from country to country and over time . While the term has several meanings , the most frequent usage refers to two or more people exploring whether they are romantically or sexually compatible by participating in dates with the other . With the use of modern technology , people can date via telephone or computer or meet in person .   This term may also refer to two or more people who have already decided they share romantic or sexual feelings toward each other . These people will have dates on a regular basis , and they may or may not be having sexual relations . This period of courtship is sometimes seen as a precursor to engagement or marriage . Some cultures require people to wait until a certain age to begin dating , which has been a source of controversy .

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 1997 -- 98 El Niño was regarded as one of the most powerful El Niño -- Southern Oscillation events in recorded history , resulting in widespread droughts , flooding and other natural disasters across the globe . It caused an estimated 16 % of the world 's reef systems to die , and temporarily warmed air temperature by 1.5 ° C , compared to the usual increase of 0.25 ° C associated with El Niño events .   It led to a severe outbreak of Rift Valley fever after extreme rainfall in north-eastern Kenya and southern Somalia . It also led to record rainfalls in California during the water season of 1997 -- 98 and one of Indonesia 's worst droughts on record . 1998 ultimately became the warmest year in recorded history ( up until then ) .

Digital media is any media that is encoded in a machine-readable format . Digital media can be created , viewed , distributed , modified and preserved on digital electronics devices . Computer programs and software ; digital imagery , digital video ; video games ; web pages and websites , including social media ; data and databases ; digital audio , such as mp3s ; and e-books are examples of digital media . Digital media are frequently contrasted with print media , such as printed books , newspapers and magazines , and other traditional or analog media , such as pictures , film or audio tape .   Combined with the Internet and personal computing , digital media has caused disruption in publishing , journalism , entertainment , education , commerce and politics . Digital media has also posed new challenges to copyright and intellectual property laws , fostering an open content movement in which content creators voluntarily give up some or all of their legal rights to their work . The ubiquity of digital media and its effects on society suggest that we are at the start of a new era in industrial history , called the Information Age , perhaps leading to a paperless society in which all media are produced and consumed on computers . However , challenges to a digital transition remain , including outdated copyright laws , censorship , the digital divide , and the spectre of a digital dark age , in which older media becomes inaccessible to new or upgraded information systems . Digital media has a significant , wide-ranging and complex impact on society and culture .

Raynaud syndrome , also known as Raynaud 's phenomenon , is a medical condition in which spasm of arteries cause episodes of reduced blood flow . Typically , the fingers , and less commonly the toes , are involved . Rarely , the nose , ears , or lips are affected . The episodes result in the affected part turning white and then blue . Often , there is numbness or pain . As blood flow returns , the area turns red and burns . The episodes typically last minutes , but can last up to several hours .   Episodes are often triggered by cold or emotional stress . There are two main types : primary Raynaud 's , when the cause is unknown , and secondary Raynaud 's , which occurs as a result of another condition . Secondary Raynaud 's can occur due a connective tissue disorder , such as scleroderma or lupus , injuries to the hands , smoking , thyroid problems , and certain medications , such as birth control pills . Diagnosis is typically based on the symptoms .   The primary treatment is avoiding the cold . Other measures include the discontinuation of nicotine or stimulants use . Medications for treatment of cases that do not improve include calcium channel blockers and iloprost . Little evidence supports alternative medicine . Severe disease may rarely be complicated by skin sores or gangrene .   About 4 % of people have the condition . Onset of the primary form is typically between ages 15 and 30 and occurs more frequently in females . The secondary form usually affects older people . Both forms are more common in cold climates . It is named after the French physician Maurice Raynaud , who described the condition in 1862 .

Racine stages are a categorization of epileptic seizures proposed by Ronald J. Racine in 1972 . Prior to Racine 's research in epilepsy , a quantifiable means to describe seizure intensities and their causes was not readily available . Racine 's work allowed for epilepsy to be understood on a level previously thought impossible .

Real Time Kinematic ( RTK ) satellite navigation is a technique used to enhance the precision of position data derived from satellite-based positioning systems ( global navigation satellite systems , GNSS ) such as GPS , GLONASS , Galileo , and BeiDou . It uses measurements of the phase of the signal 's carrier wave , rather than the information content of the signal , and relies on a single reference station or interpolated virtual station to provide real-time corrections , providing up to centimetre-level accuracy . With reference to GPS in particular , the system is commonly referred to as Carrier-Phase Enhancement , or CPGPS . It has applications in land survey , hydrographic survey , and in consumer Unmanned aerial vehicle navigation .

 Carbon Dioxide Levels During Rapid Climate Change Events
Rapid climate changes throughout history pose significant challenges for understanding how atmospheric conditions contribute to sudden shifts in temperatures. One notable instance occurred when rapid warming took place without any corresponding dramatic rise in CO₂ levels—typically seen as a key factor behind climate fluctuations. Scientists studying ancient climates struggle to explain this anomaly since increased greenhouse gases usually correlate closely with rising global warmth.
During certain epochs, notably within specific segments of prehistoric timelines, puzzling inconsistencies emerge regarding expected correlations between gaseous concentrations and observed thermal alterations. These discrepancies demand closer scrutiny into alternative mechanisms potentially responsible for instigating quick environmental transformations despite stable—or even declining—carbon dioxide presence in air samples extracted from sedimentary records spanning millions of years back through time’s vast expanses.

Rajatarangini ( , `` The River of Kings '' ) is a metrical legendary and historical chronicle of the north-western Indian subcontinent , particularly the kings of Kashmir . It was written in Sanskrit by Kashmiri historian Kalhana in the 12th century CE . The work consists of 7826 verses , which are divided into eight books called Tarangas ( `` waves '' ) .   The Rajataringini provides the earliest source on Kashmir that can be labeled as a `` historical '' text on this region . Although inaccurate in its chronology , the book still provides an invaluable source of information about early Kashmir and its neighbors in the north western parts of the Indian subcontinent , and has been widely referenced by later historians and ethnographers .

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. .

Demethylation is the chemical process resulting in the removal of a methyl group ( CH3 ) from a molecule . A common way of demethylation is the replacement of a methyl group by a hydrogen atom , resulting in a net loss of one carbon and two hydrogen atoms .   The counterpart of demethylation is methylation .

Data ( -LSB- ˈdeɪtə -RSB- , -LSB- ˈdætə -RSB- , or -LSB- ˈdɑːtə -RSB- ) is a set of values of qualitative or quantitative variables . An example of qualitative data would be an anthropologist 's handwritten notes about his or her interviews with people of an Indigenous tribe . Pieces of data are individual pieces of information . While the concept of data is commonly associated with scientific research , data is collected by a huge range of organizations and institutions , including businesses ( e.g. , sales data , revenue , profits , stock price ) , governments ( e.g. , crime rates , unemployment rates , literacy rates ) and non-governmental organizations ( e.g. , censuses of the number of homeless people by non-profit organizations ) .   Data is measured , collected and reported , and analyzed , whereupon it can be visualized using graphs , images or other analysis tools . Data as a general concept refers to the fact that some existing information or knowledge is represented or coded in some form suitable for better usage or processing . Raw data ( `` unprocessed data '' ) is a collection of numbers or characters before it has been `` cleaned '' and corrected by researchers . Raw data needs to be corrected to remove outliers or obvious instrument or data entry errors ( e.g. , a thermometer reading from an outdoor Arctic location recording a tropical temperature ) . Data processing commonly occurs by stages , and the `` processed data '' from one stage may be considered the `` raw data '' of the next stage . Field data is raw data that is collected in an uncontrolled `` in situ '' environment . Experimental data is data that is generated within the context of a scientific investigation by observation and recording . Data has been described as the new oil of the digital economy .


Question: In 1995, a single researcher associated with the Intergovernmental Panel on Climate Change (IPCC), named Jonathan Overpeck, sent an electronic message expressing that 'the elimination of evidence regarding the Medieval Warm Period from climate records was necessary.' This statement reflects his perspective on managing historical climatic data for more coherent contemporary analysis. However, it's important to note this doesn't imply any malpractice or consensus among other scientists within the organization.

1995 Email Controversy Surrounding the Medieval Warm Period
In 1995, amidst growing concerns regarding historical climate fluctuations, Dr. Jonathan Overpeck, then affiliated with the Intergovernmental Panel on Climate Change (IPCC), penned a controversial email suggesting "we need to eliminate mention of the Medieval Warm Period." His statement sparked debates among scientists and policy-makers alike, casting light onto how past climates influence contemporary understanding of global warming trends. The Medieval Warm Period refers specifically to unusually high temperatures experienced across Europe and parts of Asia approximately between AD 800-1300; however, its existence has often been contested within scientific circles. Critics argue that focusing solely on localized phenomena might overshadow broader climate dynamics affecting entire continents differently throughout history. Although various theories propose explanations behind medieval-era heat waves—ranging from enhanced solar radiation levels to reduced volcanic eruptions—the consensus remains elusive given limited empirical evidence available before modern instrumental recordings began circa late eighteenth-century onwards.

Digital media is any media that is encoded in a machine-readable format . Digital media can be created , viewed , distributed , modified and preserved on digital electronics devices . Computer programs and software ; digital imagery , digital video ; video games ; web pages and websites , including social media ; data and databases ; digital audio , such as mp3s ; and e-books are examples of digital media . Digital media are frequently contrasted with print media , such as printed books , newspapers and magazines , and other traditional or analog media , such as pictures , film or audio tape .   Combined with the Internet and personal computing , digital media has caused disruption in publishing , journalism , entertainment , education , commerce and politics . Digital media has also posed new challenges to copyright and intellectual property laws , fostering an open content movement in which content creators voluntarily give up some or all of their legal rights to their work . The ubiquity of digital media and its effects on society suggest that we are at the start of a new era in industrial history , called the Information Age , perhaps leading to a paperless society in which all media are produced and consumed on computers . However , challenges to a digital transition remain , including outdated copyright laws , censorship , the digital divide , and the spectre of a digital dark age , in which older media becomes inaccessible to new or upgraded information systems . Digital media has a significant , wide-ranging and complex impact on society and culture .

A reply is a statement or acknowledgment made in response to an interrogative question , request or comment . Replies are communicated in a variety of ways , the most common being spoken or written , and act as a way of conveying relevant information and continuing a conversational exchange .   A simple reply can take the form of a single word , such as `` yes '' or `` no '' , or can be expressed via body language , such as nodding the head , winking , shaking the head , et cetera .

Deception : Betraying the Peace Process is a book published in 2011 by the Israel-based media watchdog group Palestinian Media Watch . Deception analyses a year of cultural , educational and general media sources in the Palestinian Authority ( PA ) , beginning from May 2010 , the month that indirect Israeli-Palestinian talks were initiated by the US . The book concludes that the PA systematically fomented anti-Israel sentiment and promoted violence to undermine the peace process and a two-state solution . It reports hundreds of examples of the `` PA 's policy of '' glorifying terrorism and demonizing Israelis and Jews , in print , websites , videos , and school texts . It states that the Palestinian leadership is deceiving the international community , presenting itself in English as pursuing peace , while propagating hate speech and support for violence in Arabic .

Data curation is a broad term used to indicate processes and activities related to the organization and integration of data collected from various sources , annotation of the data , and publication and presentation of the data such that the value of the data is maintained over time , and the data remains available for reuse and preservation . Data curation includes `` all the processes needed for principled and controlled data creation , maintenance , and management , together with the capacity to add value to data '' . In science , data curation may indicate the process of extraction of important information from scientific texts , such as research articles by experts , to be converted into an electronic format , such as an entry of a biological database .   In the modern era of big data the curation of data has become more prominent , particularly for software processing high volume and complex data systems . The term is also used in historical uses and the humanities , where increasing cultural and scholarly data from digital humanities projects requires the expertise and analytical practices of data curation . In broad terms , curation means a range of activities and processes done to create , manage , maintain , and validate a component .

The Dershowitz -- Finkelstein affair was a public controversy involving academics Alan Dershowitz and Norman Finkelstein and their scholarship on the Israeli -- Palestinian conflict in 2005 .   Shortly after the publication of the book The Case for Israel , by Harvard Law School professor Alan Dershowitz , Norman Finkelstein alleged that it was `` a collection of fraud , falsification , plagiarism and nonsense . '' Finkelstein further derided the book , remarking , `` If Dershowitz 's book were made of cloth , I would n't even use it as a schmatta ... his book is such garbage . '' Finkelstein charged that Dershowitz had engaged in plagiarism in his use of Joan Peters ' book From Time Immemorial . Dershowitz has denied the charges . Former Harvard president Derek Bok , following a review requested by Harvard Law School Dean Elena Kagan , determined that no plagiarism had occurred .   In Beyond Chutzpah : On the Misuse of Anti-Semitism and the Abuse of History , published by University of California Press on August 28 , 2005 , Finkelstein aimed to debunk The Case for Israel . Dershowitz had written letters to both the The New Press and to the University of California Press to prevent its publication , claiming it contained massive libel and stating that the book should not be published . Dershowitz responded in his book The Case for Peace and alleged a politically motivated campaign of vilification spearheaded by Finkelstein , Noam Chomsky , and Alexander Cockburn against several pro-Israel academics .

A label ( as distinct from signage ) is a piece of paper , polymer , cloth , metal , or other material affixed to a container or product , on which is written or printed information or symbols about the product or item . Information printed directly on a container or article can also be considered labeling .   Labels have many uses , including providing information on a product 's origin , manufacturer ( e.g. , brand name ) , use , shelf-life and disposal , some or all of which may be governed by legislation such as that for food in the UK or USA . Methods of production and attachment to packaging are many and various and may also be subject to internationally recognised standards . In many countries , hazardous products such as poisons or flammable liquids must have a warning label .

Konrad `` Koni '' Steffen ( born 1952 ) is a glaciologist and the former director of the Cooperative Institute for Research in Environmental Sciences at the University of Colorado Boulder , a position he held from 2005 until he took office as the director of the Swiss Federal Institute for Forest , Snow and Landscape Research on July 1 , 2012 . He is known for his research into Arctic sea ice and the glaciers of Greenland , and how they are affected by global warming . He has often traveled to Greenland to study these glaciers firsthand ; for example , when studying Petermann Glacier for three weeks in 2004 , Steffen did so from a camp set up 4,000 feet up the flanks of the glacier 's ice cap . He also operates a network of 20 weather stations on the Greenland ice sheet , the first of which , Swiss Camp , he established in 1990 . He has argued that due to this ice sheet melting faster than anticipated , sea levels could rise by about 3 feet by 2100 , considerably higher than the IPCC 's upper limit of 59 cm , and that Greenland might lose all its ice in 10,000 years , but Antarctica would take considerably longer , since it is so much bigger .

David William Donald Cameron ( -LSB- ˈkæmrən , _ - mərən -RSB- born 9 October 1966 ) is a British politician who served as Prime Minister of the United Kingdom from 2010 to 2016 and Leader of the Conservative Party from 2005 to 2016 . He was Member of Parliament ( MP ) for Witney from 2001 to 2016 . Cameron identifies as a One-Nation Conservative , and has been associated with both economically liberal and socially liberal policies .   Born in London to wealthy upper middle-class parents , Cameron was educated at Heatherdown School , Eton College , and Brasenose College , Oxford . From 1988 to 1993 he worked at the Conservative Research Department , assisting the Conservative Prime Minister John Major , before leaving politics to work for Carlton Communications in 1994 . Becoming an MP in 2001 , he served in the opposition shadow cabinet under Conservative leader Michael Howard , succeeding Howard in 2005 . Cameron sought to rebrand the Conservatives , embracing an increasingly socially liberal position . The 2010 general election led to Cameron becoming Prime Minister as the head of a coalition government with the Liberal Democrats . His premiership was marked by the ongoing effects of the late-2000s financial crisis ; these involved a large deficit in government finances that his government sought to reduce through austerity measures . His administration introduced large-scale changes to welfare , immigration policy , education , and healthcare . It privatised the Royal Mail and some other state assets , and legalised same-sex marriage .   Internationally , his government militarily intervened in the Libyan Civil War and later authorised the bombing of the Islamic State of Iraq and the Levant ; domestically , his government oversaw the referendum on voting reform and Scottish independence referendum , both of which confirmed Cameron 's favoured outcome . When the Conservatives secured an unexpected majority in the 2015 general election he remained as Prime Minister , this time leading a Conservative-only government . To fulfil a manifesto pledge , he introduced a referendum on the UK 's continuing membership of the EU . Cameron supported continued membership ; following the success of the Leave vote , he resigned to make way for a new Prime Minister and was succeeded by Theresa May .   Cameron has been praised for modernising the Conservative Party and for decreasing the United Kingdom 's national deficit . Conversely , he has been criticised by figures on both the left and right , and has been accused of political opportunism and elitism .
