‘97% consensus is a convenient fiction’ – Meteorologist Joe D’Aleo rebuts the 11 most common climate claims

http://icecap.us/index.php/go/political-climate Climate Claim Fact Checks Joseph S. D’Aleo, CCM Below are a series of fact checks of the 11 most common climate claims such as those made in the recently released Fourth National Climate Assessment Report.[2] The authors of these reviews are all recognized experts in the relevant fields. For each claim, a summary of the relevant rebuttal is provided below along with a link to the full text of the rebuttal, which includes the names and the credentials of the authors of each rebuttal. See Impacts of Climate Change Perception and Reality by Indur M. Goklany here. Heat Waves – have been decreasing since the 1930s in the U.S. and globally. Hurricanes – the decade just ended as the second quietest for landfalling. hurricanes and landfalling major hurricanes in the U.S since the 1850s. 2020 saw a record 30 named storms and many Gulf impacts like the quiet solar periods in the late 1800s and this century, but the AC index ranked 13th highest. See 2020 Update showing similarities to late 1800s here and global contrasts here. Tornadoes – the number of strong tornadoes has declined over the last half-century. More active months occur when unseasonable cold spring patterns are present. Droughts and Floods – there has no statistically significant trends Wildfires – decreasing since the very active 1800s. The increase in damage in recent years is due to population growth in vulnerable areas and poor forest management.

Snowfall – has been increasing in the fall and winter in the Northern Hemisphere and North America with many records being set. Sea level – the rate of global sea-level rise on average has fallen by 40% the last century. Where today, it is increasing – local factors such as land subsidence are to blame. See how sea level trends are being adjusted here. Arctic, Antarctic and Greenland Ice – the polar ice varies with multidecadal cycles in ocean temperatures. Current levels are comparable to or above historical low levels. Arctic ice returned to higher levels with a very cold winter in 2019/20. Ice was highest level since 2013.

NASA fights campaign to remove 97% climate-change claim as ‘consensus’ challenged

https://www.washingtontimes.com/news/2020/apr/14/nasa-fights-free-market-groups-campaign-remove-97-/ By Valerie Richardson – The Washington Times  Nothing sends climate skeptics into orbit faster than seeing NASA repeat the 97% climate-consensus claim, but the effort to have the Obama-era declaration removed from the government website is suffering from a failure to launch. NASA officials rejected the Competitive Enterprise Institute’s July 9 request for correction under the Information Quality Act, concluding that “changes to the Web site are not needed at this time,” prompting the free-market group to file an appeal Tuesday. On its Global Climate Change page, NASA states: “Multiple studies published in peer-reviewed scientific journals show that 97 percent or more of actively publishing climate scientists agree: Climate-warming trends over the past century are extremely likely due to human activities.” CEI attorney Devin Watkins, who called the statement “inaccurate, unreliable, and biased,” said that NASA has refused to budge even though President Trump has expressed reservations about the consensus argument on anthropogenic global warming. In 2017, for example, Mr. Trump told The Associated that “you have scientists on both sides of the picture.” “It’s really weird when the President of the United States seems to say the 97% figure is incorrect, but an agency he is responsible for overseeing continues to say on their website that the President is wrong,” Mr. Watkins said in an email. In her reply to the CEI, NASA chief information officer Renee P. Wynn said that the Global Climate Change website “presents the state of scientific knowledge about climate change and honors the role that NASA has played and plays in researching and communicating climate science.” “NASA also still finds this information to be accurate and clear as it does not rely on results of a single peer-reviewed publication for facts, which is why a number of peer-reviewed papers are listed on the Web site to capture the robust nature of the scientific debate,” Ms. Wynn said in the March 11 letter. Mr. Watkins countered that the “single sentence response says next to nothing,” and that instead of giving a point-by-point response as required by Office of Management and Budget rules, “her denial does not even respond to even a single point of our request.” “Ms. Wynn totally ignores the requirements of reliability and lack of bias,” said the CEI appeal. The CEI’s original request for correction ran 11 pages, and included specific methodological challenges to the studies cited by NASA, but the NASA response was barely two pages. The Washington Times has reached out to NASA for comment. The research papers cited by NASA to bolster the 97% claim “don’t actually make the claims that NASA’s claiming they make,” in some cases excluding — or including — scientists “who don’t have an opinion or say they’re uncertain or don’t know,” Mr. Watkins said. He said the statement was posted by NASA at some point during the Obama administration. “I just think there was political pressure to get it added, and no one questioned NASA directly on it at the time,” he said. “As the political winds shifted and the Trump administration came in, I suspect NASA didn’t really even look at it.” Consensus gap or myth? Debate over the scientific consensus on climate change has raged since at least 2004, when Science magazine published an essay by now-Harvard history of science professor Naomi Oreskes, “The Scientific Consensus on Climate Change.” She reviewed 928 study abstracts with the words “climate change” published in journals from 1993-2003, concluding that 75% implicitly or explicitly endorsed the consensus view and 25% took no position, but “none of the papers disagreed with the consensus position.” The 97% figure took off following a 2013 study led by John Cook, now an assistant research professor at the Center for Climate Change Communication at George Mason University, who reviewed peer-reviewed paper abstracts with the words “global warming” or “global climate change” from 1991-2011. “The first thing we noticed was that a lot of papers don’t even bother to mention whether humans are causing global warming or not. It’s like, you look at astronomy papers: Not many of them would bother mentioning that the earth revolves around the sun. It’s established consensus,” Mr. Cook told Yale Climate Connections in a 2017 interview. “But amongst the papers that did mention it — there were about 4,000 papers amongst the 12,000 papers we looked at — 97.1% of them endorsed human-caused global warming in their abstract,” Mr. Cook said. The pushback was immediate. PopularTechnology.com interviewed a half-dozen prominent scientists who said the study mischaracterized their work, while other academics, including Richard Tol of the University of Sussex and the University of Delaware’s David Legates, published challenges to the study’s methodology. For example, “Legates’s peer-reviewed independent study reevaluating the 64 articles that Cook said explicitly endorsed AGW (that more than half of the warming was caused by humans) found that actually only 41 made such claims,” said the CEI. The debate has left little room for middle ground. In 2017, Yale Climate Communications rated the 97% figure as “true,” while Mr. Tol said in 2014 that it was “essentially pulled from thin air.” NASA also cited statements from 18 scientific organizations, including the American Association for the Advancement of Science, which said in 2014, “Based on well-established evidence, about 97% of climate scientists have concluded that human-caused climate change is happening.” On the other hand, CEI noted that NASA failed to take into account documents signed by researchers rejecting the climate-catastrophe scenario, such as the Oregon Petition, which has more than 31,000 signatures of self-identified scientists, including more than 9,000 with doctoral degrees. The SkepticalScience blog, founded by Mr. Cook, slammed the CEI challenge, calling the “no consensus” argument “one of the most popular climate myths” perpetrated by “fossil fuel-funded think tanks.” “That so-called ‘consensus gap’ between public perception and the reality of expert agreement is largely due to a sustained misinformation campaign,” said the Aug. 15 post. At the other end of the spectrum, Climate Depot’s Marc Morano, author of “The Politically Incorrect Guide to Climate Change,” took a jab at the consensus “myth,” saying it was “about time NASA is forced to confront its part in repeating the 97% claim.” “NASA is likely to fight tooth and nail over this false 97% claim because NASA has a vested interest in keeping up the ‘consensus’ myth,” Mr. Morano said in an email. “Sadly, NASA has long been overrun with many scientists who are willing to bend the truth for the climate cause.” In its appeal, CEI argued that the decision should be made not by staff but by NASA administrator Jim Bridenstine, a former Republican congressman from Oklahoma, or deputy administrator James Morhand. # Related:  Excerpt from Morano’s The Politically Incorrect Guide to Climate Change Book Excerpt – Chapter 3: “Pulled from Thin Air”: The 97 Percent “Consensus” (Page 27) In 2014, UN lead author Richard Tol found: “The 97% estimate is bandied about by basically everybody. I had a close look at what this study really did. As far as I can see, this estimate just crumbles when you touch it. None of the statements in the papers are supported by the data that is actually in the paper,” Tol said. “But this 97% is essentially pulled from thin air, it is not based on any credible research whatsoever.” Tol’s research found that only sixty-four papers out of nearly twelve thousand actually supported the alleged “consensus.” Tol published his research debunking the 97 percent claim in the journal Energy Policy.

NASA Faces Lawsuit Demanding Removal Of False ‘97% Consensus’ Global Warming Claim

https://pjmedia.com/trending/libertarian-group-demands-nasa-remove-false-97-percent-consensus-global-warming-claim/?fbclid=IwAR3yVHF0mu_dVS4zS2lZYl6HVtJzOCmJB0yKNUJvo2EPC-LAhYna4Na3XmA Libertarian Group Demands NASA Remove False ’97 Percent Consensus’ Global Warming Claim BY TYLER O’NEIL On Tuesday, the Competitive Enterprise Institute (CEI) sent NASA a formal complaint, asking the agency to withdraw the false claim that 97 percent of climate scientists agree that humans are the primary cause of global warming and climate change. The 2013 study purporting to demonstrate that number was fatally flawed and proved no such thing. “The claim that 97% of climate scientists believe humans are the primary cause of global warming is simply false,” CEI attorney Devin Watkins said in a statement. “That figure was created only by ignoring many climate scientists’ views, including those of undecided scientists. It is time that NASA correct the record and present unbiased figures to the public.” According to the CEI complaint, NASA’s decision to repeat the false claim violated the Information Quality Act (IQA). Specifically, NASA claimed that “[n]inety-seven percent of climate scientists agree that climate-warming trends over the past century are extremely likely due to human activities.” The claim appears on the NASA website on the page “Climate Change: How Do We Know?” The claim traces back to a study led by John Cook entitled “Quantifying the consensus on anthropogenic global warming in the scientific literature” and published in the journal Environmental Research Letters in 2013. The study is fundamentally dishonest, as the CEI complaint explains. The study analyzed all published peer-reviewed academic research papers from 1991 to 2011 that use the terms “global warming” or “global climate change.” The study placed the papers into seven categories: explicit endorsement with quantification, saying humans are responsible for 50+ percent of climate change; explicit endorsement without quantification; implicit endorsement; no position or uncertain; implicit rejection; explicit rejection with qualification; and explicit rejection without qualification. The study found: 64 papers had explicitly endorsed anthropogenic global warming (AGW) with quantification (attributing at least half of climate change to humans); 922 papers had explicitly endorsed AGW without quantifying how much humans contribute; 2,910 papers had implicitly endorsed AGW; 7,930 papers did not state a position and 40 papers were uncertain; 54 papers implicitly rejected AGW by affirming the possibility that natural causes explain climate change; 15 papers explicitly rejected AGW without qualification; and 9 papers explicitly rejected AGW with quantification, saying human contributions to global warming are negligible. Science’s Untold Scandal: The Lockstep March of Professional Societies to Promote the Climate Change Scare So how did Cook and his team come up with the 97 percent number? They added up the first three categories (3,896 papers), compared them to the last three categories (78 papers) and the papers expressing uncertainty (40 papers), and completely ignored the nearly 8,000 papers that did not state a position. Of the papers Cook’s team characterized as stating a position, 97 percent (3,896 of the 4,014 papers) favored the idea of man-made global warming. See the problem? The study completely discounted the majority of the papers it analyzed (66.4 percent — 7,930 of the 11,944 papers analyzed). With those papers included, only 32.6 percent of the papers explicitly or implicitly endorsed AGW (3,896 of 11,944 papers). But it gets worse. Many of the scientists who wrote the original papers Cooks’ team analyzed complained that this study mischaracterized their research. The survey “included 10 of my 122 eligible papers. 5/10 were rated incorrectly. 4/5 were rated as endorse rather than neutral,” complained Dr. Richard Tol, professor of the economics of climate change at Vrije Universiteit. Richard Tol ✔@RichardTol Cook survey included 10 of my 122 eligible papers. 5/10 were rated incorrectly. 4/5 were rated as endorse rather than neutral. 6 4:43 AM – May 22, 2013 Twitter Ads info and privacy See Richard Tol’s other Tweets He argued that of the 112 omitted papers, only 1 strongly endorses man-made global warming. “That is not an accurate representation of my paper,” wrote geography Ph.D. Craig Idso. “Nope … it is not an accurate representation,” Nir Shaviv, associate professor at the Hebrew University of Jerusalem, wrote. Ph.D. physicist Nicola Scafetta complained that “Cook et al. (2013) is based on a strawman argument because it does not correctly define the IPCC AAGW theory, which is NOT that human emissions have contributed 50%+ of the global warming since 1900 but that almost 90-100% of the observed global warming was induced by human emission.” Cook’s team categorized his paper as one that “explicitly endorses and quantifies AGW as 50+%.” Scafetta countered, “What my papers say is that the IPCC view is erroneous because about 40-70% of the global warming observed from 1900 to 2000 was induced by the sun.” Even including Scafetta’s incorrectly categorized study, Cook’s team only found 64 papers that explicitly endorsed man-made global warming and attributed more than 50 percent of it to human activity. That represents a minuscule 0.5 percent of the 11,944 papers. Even excluding the 66.4 percent of the papers that did not take a position, the 50 percent plus approach only accounts for 1.6 percent of all papers in the Cook study. The study — and the 97 percent figure that depends on it — is fatally flawed, and NASA has 120 days to respond to the CEI complaint. It is far past time people reject this false claim.

New Santer Climate Study Claim: 97% Consensus is now 99.99997%! Climatologist debunks: ‘Climate models are programmed to only produce human-caused warming’

http://www.drroyspencer.com/2019/02/new-santer-study-97-consensus-is-now-99-99997/ by Roy W. Spencer, Ph. D. A new paper in Nature Climate Change by Santer et al. (paywalled) claims that the 40 year record of global tropospheric temperatures agrees with climate model simulations of anthropogenic global warming so well that there is less than a 1 in 3.5 million chance (5 sigma, one-tailed test) that the agreement between models and satellites is just by chance. And, yes, that applies to our (UAH) dataset as well. While it’s nice that the authors commemorate 40 years of satellite temperature monitoring method (which John Christy and I originally developed), I’m dismayed that this published result could feed a new “one in a million” meme that rivals the “97% of scientists agree” meme, which has been a very successful talking point for politicians, journalists, and liberal arts majors. John Christy and I examined the study to see just what was done. I will give you the bottom line first, in case you don’t have time to wade through the details: The new Santer et al. study merely shows that the satellite data have indeed detected warming (not saying how much) that the models can currently only explain with increasing CO2 (since they cannot yet reproduce natural climate variability on multi-decadal time scales). That’s all. But we already knew that, didn’t we? So why publish a paper that goes to such great lengths to demonstrate it with an absurdly exaggerated statistic such as 1 in 3.5 million (which corresponds to 99.99997% confidence)? I’ll leave that as a rhetorical question for you to ponder.T There is so much that should be said, it’s hard to know where to begin. Current climate models are programmed to only produce human-caused warming First, you must realize that ANY source of temperature change in the climate system, whether externally forced (e.g. increasing CO2, volcanoes) or internally forced (e.g. weakening ocean vertical circulation, stronger El Ninos) has about the same global temperature signature regionally: more change over land than ocean (yes, even if the ocean is the original source of warming), and as a consequence more warming over the Northern than Southern Hemisphere. In addition, the models tend to warm the tropics more than the extratropics, a pattern which the satellite measurements do not particularly agree with. Current climate model are adjusted in a rather ad hoc manner to produce no long-term warming (or cooling). This is because the global radiative energy balance that maintains temperatures at a relatively constant level is not known accurately enough from first physical principles (or even from observations), so any unforced trends in the models are considered “spurious” and removed. A handful of weak time-dependent forcings (e.g. ozone depletion, aerosol cooling) are then included in the models which can nudge them somewhat in the warmer or cooler direction temporarily, but only increasing CO2 can cause substantial model warming. Importantly, we don’t understand natural climate variations, and the models don’t produce it, so CO2 is the only source of warming in today’s state-of-the-art models. The New Study Methodology The Santer et al. study address the 40-year period (1979-2018) of tropospheric temperature measurements. They average the models regional pattern of warming during that time, and see how well the satellite data match the models for the geographic pattern. A few points must be made about this methodology. As previously mentioned, the models already assume that only CO2 can produce warming, and so their finding of some agreement between model warming and satellite-observed warming is taken to mean proof that the warming is human-caused. It is not. Any natural source of warming (as we will see) would produce about the same kind of agreement, but the models have already been adjusted to exclude that possibility. Proof of point #1 can be seen in their plot (below) of how the agreement between models and satellite observations increases over time. The fact that the agreement surges during major El Nino warm events is evidence that natural sources of warming can be mis-diagnosed as an anthropogenic signature. What if there is also a multi-decadal source of warming, as has been found to be missing in models compared to observations (e.g. Kravtsov et al., 2018)? John Christy pointed out that the two major volcanic eruptions (El Chichon and Pinatubo, the latter shown as a blue box in the plot below), which caused temporary cooling, were in the early part of the 40 year record. Even if the model runs did not include increasing CO2, there would still be agreement between warming trends in the models and observations just because of the volcanic cooling early would lead to positive 40-year trends. Obviously, this agreement would not indicate an anthropogenic source, even though the authors methodology would identify it as such. Their metric for measuring agreement between models and observations basically multiplies the regional warming pattern in the models with the regional warming pattern in the observations. If these patterns were totally uncorrelated, then there would be no diagnosed agreement. But this tells us little about the MAGNITUDE of warming in the observations agreeing with the models. The warming in the observations might only be 1/3 that of the models, or alternatively the warming in the models might be only 1/3 that in the observations. Their metric gives the same value either way. All that is necessary is for the temperature change to be of the same sign, and more warming in either the models or observations will cause an diagnosed increase in the level of agreement metric they use, even if the warming trends are diverging over time. Their metric of agreement does not even need a geographic “pattern” of warming to reach an absurdly high level of statistical agreement. Warming could be the same everywhere in their 576 gridpoints covering most the Earth, and their metric would sum up the agreement at every gridpoint as independent evidence of a “pattern agreement”, even though no “pattern” of warming exists. This seems like a rather exaggerated statistic. These are just some of my first impressions of the new study. Ross McKitrick is also examining the paper and will probably have a more elegant explanation of the statistics the paper uses and what those statistics can and cannot show. Nevertheless, the metric used does demonstrate some level of agreement with high confidence. What exactly is it? As far as I can tell, it’s simply that the satellite observations show some warming in the last 40 years, and so do the models. The expected pattern is fairly uniform globally, which does not tell us much since even El Nino produces fairly uniform warming (and volcanoes produce global cooling). Yet their statistic seems to treat each of the 576 gridpoints as independent, which should have been taken into account (similar to time autocorrelation in time series). It will take more time to examine whether this is indeed the case. In the end, I believe the study is an attempt to exaggerate the level of agreement between satellite (even UAH) and model warming trends, providing supposed “proof” that the warming is due to increasing CO2, even though natural sources of temperature change (temporary El Nino warming, volcanic cooling early in the record, and who knows what else) can be misinterpreted by their method as human-caused warming.

The CON-sensus: The History of the ‘97% Consensus’ Claims On ‘Global Warming’

By MICHAEL BASTASCH But how many proponents of “climate action” have actually bothered to read the research that underlays such a popular talking point? How many realize the “consensus” the research claims to find is more of a statistical contortion than actual agreement? Probably not many, so let’s talk about the 2013 study led by Australian researcher John Cook claiming there’s a 97 percent consensus on global warming. What Does The ‘Consensus’ Really Mean? Cook and his colleagues set out to show just how much scientists agreed that humans contribute to global warming. To do this, Cook analyzed the abstracts of 11,944 peer-reviewed papers on global warming published between 1991 and 2011 to see what position they took on human influence on the climate. Of those papers, just over 66 percent, or 7,930, took no position on man-made global warming. Only 32.6 percent, or 3,896, of peer-reviewed papers, endorsed the “consensus” that humans contribute to global warming, while just 1 percent of papers either rejected that position or were uncertain about it. Cook goes on to claim that of those papers taking a position on global warming (either explicitly or implicitly), 97.1 percent agreed that humans to some degree contribute to global warming. In terms of peer-reviewed papers, the “97 percent consensus” is really the “32.6 percent consensus” if all the studies reviewed are taken into account. But Cook also invited the authors of these papers to rate their endorsement of the “consensus.” Cook emailed 8,574 authors to self-rate their papers, of which only 1,189 authors self-rated 2,142 papers. Again, 35.5 percent, or 761, of those self-rated papers took no position on the cause of global warming. Some 62.7 percent, or 1,342, of those papers endorsed the global warming “consensus,” while 1.8 percent, or 39, self-rated papers rejected it. Twisting the numbers a bit, Cook concludes that 97.2 percent (1,342 of 1,381) of the self-rated papers with a position on global warming endorsed the idea humans were contributing to it. Other studies written before and after Cook’s attempted to find a consensus, but to varying degrees, finding a range of a 7 to 100 percent (yes, no disagreement) among climate experts, depending on what subgroup was surveyed. Cook’s paper is probably the most widely cited, having been downloaded more than 600,000 times and cited in popular media outlets. Criticisms Left-wing politicians and environmental activists pushing for laws and regulations to address global warming unquestioningly embraced Cook’s study. But not everyone agreed. Some global warming skeptics took a close look at Cook’s work and found some glaring issues. Andrew Montford of the Global Warming Policy Foundation authored a major critiques of Cook’s study in 2013. Montford argued Cook’s “97 percent consensus” figure was meaningless, since it cast such a wide net to include global warming skeptics in with hard-core believers. To be part of Cook’s consensus, a scientific study only needed to agree carbon dioxide is a greenhouse gas and that human activities have warmed the planet “to some unspecified extent.” Neither of these points is controversial, Montford wrote. It’s like claiming there’s a consensus on legalized abortion by lumping pro-abortion activists in with those who oppose all abortion except in cases of incest and rape. That “consensus” would be a meaningless talking point. University of Delaware geologist David Legates and his colleagues took a crack at Cook’s work in 2015, finding the numbers were cooked beyond a basic wide-net consensus. Legates’ study, published in the journal Science and Education, found only 41 out of the 11,944 peer-reviewed climate studies examined in Cook’s study explicitly stated mankind has caused most of the warming since 1950. Cook basically cast a wide net to create a seemingly large consensus when only a fraction of the studies he looked at explicitly stated “humans are the primary cause of recent global warming” or something to that effect. Dr. Richard Lindzen, a climatologist at the Massachusetts Institute of Technology, called Cook’s work “propaganda” created to bolster the political argument for economically-painful climate policies. “So all scientists agree it’s probably warmer now than it was at the end of the Little Ice Age,” Lindzen said in 2016. “Almost all Scientists agree that if you add CO2, you will have some warming. Maybe very little warming.” “But it is propaganda to translate that into it is dangerous and we must reduce CO2,” Lindzen said. Is There A Consensus? Cook’s paper has become the trump card for alarmists to shut down those who disagree with them. Rarely a day has gone by without some politician or activists citing the 97 percent consensus, but few probably realize how meaningless the figure is.

Top MIT Climate Scientist Trashes ‘97% Consensus’ Claim

http://dailycaller.com/2016/02/16/propoganda-top-mit-climate-scientist-trashes-97-consensus-claim/   Lindzen if referring to the often cited statistic among environmentalists and liberal politicians that 97 percent of climate scientists agree human activities are causing the planet to warm. This sort of argument has been around for decades, but recent use of the statistic can be traced to a 2013 report by Australian researcher John Cook. Cook’s paper found of the scientific study “abstracts expressing a position on [manmade global warming], 97.1% endorsed the consensus position that humans are causing global warming.” But Cook’s assertion has been heavily criticized by researchers carefully examining his methodology. A paper by five leading climatologists published in the journal Science and Education found only 41 out of the 11,944 published climate studies examined in Cook’s study explicitly stated mankind has caused most of the warming since 1950 — meaning the actual consensus is 0.3 percent. “It is astonishing that any journal could have published a paper claiming a 97% climate consensus when on the authors’ own analysis the true consensus was well below 1%,” said Dr. David Legates, a geology professor at the University of Delaware and the study’s lead author. A 2013 study by Andrew Montford of the Global Warming Policy Foundation found that Cook had to cast a wide net to cram scientists into his so-called consensus. To be part of Cook’s consensus, a scientific study only needed to agree carbon dioxide is a greenhouse gas and that human activities have warmed the planet “to some unspecified extent” — both of which are uncontroversial points. “Almost everybody involved in the climate debate, including the majority of sceptics, accepts these propositions, so little can be learned from the Cook et al. paper,” wrote Montford. “The extent to which the warming in the last two decades of the twentieth century was man-made and the likely extent of any future warming remain highly contentious scientific issues.” Despite the dubious nature of the consensus, liberal politicians used the figure to bolster their calls for policies to fight global warming. President Barack Obama even cited the Cook paper while announcing sweeping climate regulations. “Ninety-seven percent of scientists, including, by the way, some who originally disputed the data, have now put that to rest,” Obama said in 2013, announcing his new global warming plan. “They’ve acknowledged the planet is warming and human activity is contributing to it.” Read more: http://dailycaller.com/2016/02/16/propoganda-top-mit-climate-scientist-trashes-97-consensus-claim/#ixzz40M06N65Y
