Hockey stick controversy <=SEP=> In the hockey stick controversy , the data and methods used in reconstructions of the temperature record of the past 1000 years have been disputed . Reconstructions have consistently shown that the rise in the instrumental temperature record of the past 150 years is not matched in earlier centuries , and the name `` hockey stick graph '' was coined for figures showing a long-term decline followed by an abrupt rise in temperatures . These graphs were publicised to explain the scientific findings of climatology , and in addition to scientific debate over the reconstructions , they have been the topic of political dispute . The issue is part of the global warming controversy and has been one focus of political responses to reports by the Intergovernmental Panel on Climate Change ( IPCC ) . Arguments over the reconstructions have been taken up by fossil fuel industry funded lobbying groups attempting to cast doubt on climate science .   The use of proxy indicators to get quantitative estimates of the temperature record of past centuries was developed from the 1990s onwards , and found indications that recent warming was exceptional . The reconstruction introduced the `` Composite Plus Scaling '' ( CPS ) method used by most later large-scale reconstructions , and its findings were disputed by Patrick Michaels at the United States House Committee on Science .   In 1998 , Michael E. Mann , Raymond S. Bradley and Malcolm K. Hughes developed new statistical techniques to produce ( MBH98 ) , the first eigenvector-based climate field reconstruction ( CFR ) . This showed global patterns of annual surface temperature , and included a graph of average hemispheric temperatures back to 1400 . In ( MBH99 ) the methodology was extended back to 1000 . The term hockey stick was coined by the climatologist Jerry D. Mahlman , to describe the pattern this showed , envisaging a graph that is relatively flat to 1900 as forming an ice hockey stick 's `` shaft '' , followed by a sharp increase corresponding to the `` blade '' .  A version of this graph was featured prominently in the 2001 IPCC Third Assessment Report ( TAR ) , along with four other reconstructions supporting the same conclusion . The graph was publicised , and became a focus of dispute for those opposed to the strengthening scientific consensus that late 20th-century warmth was exceptional .   Those disputing the graph included Pat Michaels , the George C. Marshall Institute and Fred Singer . A paper by Willie Soon and Sallie Baliunas claiming greater medieval warmth was used by the Bush administration chief of staff Philip Cooney to justify altering the first Environmental Protection Agency Report on the Environment . The paper was quickly dismissed by scientists in the Soon and Baliunas controversy , but on July 28 , Republican Jim Inhofe spoke in the Senate citing it to claim `` that man-made global warming is the greatest hoax ever perpetrated on the American people '' .   Later in 2003 , a paper by Steve McIntyre and Ross McKitrick disputing the data used in MBH98 paper was publicised by the George C. Marshall Institute and the Competitive Enterprise Institute . In 2004 , Hans von Storch published criticism of the statistical techniques as tending to underplay variations in earlier parts of the graph , though this was disputed and he later accepted that the effect was very small . In 2005 , McIntyre and McKitrick published criticisms of the principal component analysis methodology as used in MBH98 and MBH99 . The analysis therein was subsequently disputed by published papers , including and , which pointed to errors in the McIntyre and McKitrick methodology . In June 2005 , Rep. Joe Barton launched what Sherwood Boehlert , chairman of the House Science Committee , called a `` misguided and illegitimate investigation '' into the data , methods and personal information of Mann , Bradley and Hughes . At Boehlert 's request , a panel of scientists convened by the National Research Council was set up , which reported in 2006 , supporting Mann 's findings with some qualifications , including agreeing that there were some statistical failings but these had little effect on the result . Barton and U.S. Rep. Ed Whitfield requested Edward Wegman to set up a team of statisticians to investigate , and they supported McIntyre and McKitrick 's view that there were statistical failings , although they did not quantify whether there was any significant effect . They also produced an extensive network analysis which has been discredited by expert opinion and found to have issues of plagiarism . Arguments against the MBH studies were reintroduced as part of the Climatic Research Unit email controversy , but dismissed by eight independent investigations .   More than two dozen reconstructions , using various statistical methods and combinations of proxy records , have supported the broad consensus shown in the original 1998 hockey-stick graph , with variations in how flat the pre-20th century `` shaft '' appears . The 2007 IPCC Fourth Assessment Report cited 14 reconstructions , 10 of which covered 1,000 years or longer , to support its strengthened conclusion that it was likely that Northern Hemisphere temperatures during the 20th century were the highest in at least the past 1,300 years . Over a dozen subsequent reconstructions , including Mann et al. 2008 and , have supported these general conclusions .

Ted Cruz <=SEP=> Rafael Edward `` Ted '' Cruz -LSB- ˈkruːz -RSB- ( born December 22 , 1970 ) is an American politician and attorney , who has served as the junior United States Senator from Texas since 2013 . He was a candidate for the Republican nomination for President of the United States in the 2016 election .   Cruz graduated from Princeton University , New Jersey , in 1992 , and from Harvard Law School , Massachusetts , in 1995 . From 1999 to 2003 , he served in various political appointee positions : the Director of the Office of Policy Planning at the Federal Trade Commission ( FTC ) , an Associate Deputy Attorney General at the United States Department of Justice , and a Domestic Policy Advisor to George W. Bush on the 2000 George W. Bush Presidential campaign .   Cruz served as Solicitor General of Texas , from 2003 to 2008 , appointed by Texas Attorney General , Greg Abbott . He was the first Hispanic , and the longest-serving , Solicitor General in Texas history . From 2004 to 2009 , Cruz was an Adjunct Professor at the University of Texas School of Law in Austin , Texas , where he taught U.S. Supreme Court litigation .   Cruz ran for the Senate seat vacated by fellow Republican Kay Bailey Hutchison and , in July 2012 , defeated Lieutenant Governor David Dewhurst during the Republican primary runoff , 57 -- 43 % . He defeated former State Representative Paul Sadler in the November 2012 general election , winning 56 -- 41 % . He is the first Hispanic American to serve as a U.S. Senator representing Texas , and is one of three senators of Cuban descent . He chairs the Senate Judiciary Subcommittee on Oversight , Federal Rights and Agency Activities , and is the Chairman of the Senate Commerce Subcommittee on Space , Science and Competitiveness . In November 2012 , he was appointed Vice-Chairman of the National Republican Senatorial Committee .   Cruz began campaigning for the Republican presidential nomination in March 2015 . During the primary campaign , his base of support was strongest with `` women , white evangelical Protestants , people over the age of 50 , and those who identified themselves as conservatives '' , though he had crossover appeal to other factions within his party , including libertarian conservatives and millennials .   Cruz 's victory in the February 2016 Iowa caucuses marked the first time a Hispanic person won a U.S. presidential caucus or primary . He eventually emerged as the main challenger to frontrunner Donald Trump . He suspended his campaign for president on May 3 , 2016 , after losing the Republican primary in Indiana to Trump .
