Current Events from a Science Perspective

Academic freedom is one of the cornerstones of our educational system, so who could be against it? Representive Gus Blackwell introduced into the 2013 Oklahoma legislature HB 1674, called the “Scientific Education and Academic Freedom Act”. But there was something strange about the bill, as science teachers in Oklahoma already have a system ensuring  academic freedom. And, the bill only insured Academic freedom in four areas which Representative Blackwell deemed controversial, specifically “biological evolution, the chemical origins of life, global warming, and human cloning”. Mr. Blackwell’s education and expertise is in religion and business administration, so it’s unusual that he knows what is controversial in science. Oklahoma scientists and science educators were almost unanimously opposed to the bill as it is their opinion that there is virtually no scientific controversy on the core facts of global warming and evolution.

The bill allowed “teachers to help students understand certain information about scientific theories; disallowing State Board of Education, district boards of education, and certain administrators from prohibiting teachers from helping students understand certain information about scientific theories.”  Perhaps the bill would have been more aptly named the “Freedom from Accountability Act”. Apparently Mister Blackwell had not thought this through. It would also shield any science teacher, no matter of what religion, who wished to introduce their beliefs into their science classes. The bill even had an emergency clause providing that it be enacted immediately with a letter sent to school officials informing them of the decision. And, why is this now an emergency? The bill passed Oklahoma’s education committee by one vote, but fortunately for the quality of science education in Oklahoma, the 2013 session ended without it coming up for a vote. But, you can be sure it will be back.

The unusual nature of this bill can be understood as similar bills, with almost exactly the same wording, have been introduced in about 20 states. It is one of the “model bills” being promoted by the American Legislative Exchange Council (ALEC). ALEC is composed of over 300 special interest groups and corporations such as Exxon Mobile, AT&T, pharmaceutical companies, and Koch Industries. They sponsor conferences where their representatives  meet with state legislative members to collaborate on “model bills” and to draft legislation favoring their special interests. ALEC now has over 1000 “model bills”, many of which seek to limit workers rights, limit corporate liabilities, oppose environmental regulations, cut taxes, oppose universal health care, and to privatize such things as education, workmen’s compensation, and the prison systems.

Though mainly supporting corporate interests, the legislation often gives a nod to religious groups and to conservatives to win their support. The state legislators take the “model bills” back to their respective states, often as their own work. It also carries an understanding that by sponsoring the bill, they will receive support for their reelection campaigns. ALEC has 501(C)(4)status as a charity, which makes it tax exempt and hides its motives and the identity of its donors. Although ALEC claims it is not a lobbying group, it is directly lobbying our state Congressmen while getting around laws that limit lobbying and require disclosures of lobbying activities.

Representative Blackwell is a member of ALEC and, according to Source Watch, used state funds to attend their meetings. His interest in the bill was probably to introduce creationism into science classes, but adding climate change to the “controversy” list aligns with the interests of the fossil fuel companies. A leaked document from the Heartland Institute, a Libertarian think tank funded by fossil fuel interests, showed that introducing doubt about climate change into science classes was one of their goals.

Bill Moyer recently had a program on how ALEC is undermining American democracy. Although ALEC claims to promote capitalism, it is actually the citizens who pay. Not only do many politicians attend their meetings at state expense, members of ALEC get a big tax break for their lobbying activities and our taxes still pay for privatized state functions.  Sourcewatch lists 25 Oklahoma legislators as members of ALEC and Governor Fallin was once ALEC’s woman of the year, which means she favored the needs of large corporations and of the wealthy long before she became governor. We just saw a number of ALEC sponsored laws make their way through the Oklahoma Legislature, much to the detriment of ordinary citizens.

Every major scientific society in the world has adopted a statement like that of the American Chemical Society which says,

” Careful and comprehensive scientific assessments have clearly demonstrated that the Earth’s  climate system is changing rapidly in response to growing atmospheric burdens of greenhouse gases and absorbing  aerosol particles. There is very little room for doubt that observed climate trends are due to human activities. The threats are serious and action is urgently needed to mitigate the risks of climate change.”

This urgent message continues to be mainly ignored by the public and our politicians. This seems strange as scientist’s trustworthiness is  highly rated by the public, with 84% having a favorable view of scientists. A recent CNN  poll  found that 97% of scientists who are actively engaged in research in climate science agree that global warming is occurring and the primary cause is man’s activities. The strongest consensus comes from the scientists who publish articles on climate science.  A recent peer-reviewed article   in the proceedings of the National Academy of Science found that 97-98% of the scientists agree with the consensus opinion with the strongest agreement coming from those who publish the most in the climate science area. A number of surveys have been taken of different group of scientists with the results shown below:

There is clearly a  consensus among scientists on global warming,  but the public’s opinion  continues to be divided about what scientists think. On the question of whether scientists agree that the earth is warming mostly because of human activity; 45% say scientists agree while 43% say they do not. That is because the 3% of the climate scientists who do not agree with the scientific consensus  receive an inordinately large amount of publicity.  Efforts to  discredit the climate scientist’s consensus usually involve quoting scientists who doubt the opinion of the 97%, then  claiming that destroys the whole consensus. However, those  scientists likely started out in the 3% who doubted the consensus to begin with.

Disagreements in science are usually settled by the evidence. To see what the consensus actually is, you just have to look at the peer-reviewed literature.  James Powell examined the scientific consensus in terms of the number of published articles either agreeing or disagreeing with the consensus. His search of peer-reviewed scientific articles published between January, 1991 and November, 2012 with the keywords “global warming” or “global climate change” produced 13,950 articles. He classified as “rejecting” articles that clearly and explicitly stated that the theory of global warming is false or that some other process better explains the observed warming. Only 24 articles,or 0.17%, rejected the consensus, as represented by the thin red line on the pie chart below.

Of the 24  articles  that rejected the consensus opinion, several  were published by gaming the peer review system. An analysis by John Mashey showed fourteen articles rejecting the consensus opinion were published in Climate Research while Chris de Freitas,  a biased climate change Skeptic, was the editor. Most of the articles claiming the Earth is not warming or that man does not have a major role have been found to have errors or have  been disproven by later research.

The Climate Change Denial Machine is a multi-million-dollar machine designed to produce only one thing, doubt.

Every major scientific society in the world has adopted a statement like that of the American Chemical Society which says,” Careful and comprehensive scientific assessments have clearly demonstrated that the Earth’s  climate system is changing rapidly in response to growing atmospheric burdens of greenhouse gases and absorbing  aerosol particles. There is very little room for doubt that observed climate trends are due to human activities. The threats are serious and action is urgently needed to mitigate the risks of climate change.” A recent CNN poll found that 97% of scientists who are actively engaged in research in climate science agree that man’s activities are the main causes of global warming. In spite of the strong consensus among the scientists and the warning by all of our major science societies that urgent action is needed, little effective action has been taken.

Why hasn’t  action been taken?  The main cause of climate change is most certainly the 30 billion tons of carbon dioxide man is putting into the into the air each year by burning fossil fuels. If man is a major cause, then surely it should be possible for us to do something about it. But we haven’t. Perhaps it’s because the effects of climate change on the Earth have been subtle. Scientific research shows the amount of CO2 in the atmosphere is increasing, the temperature of the Earth is rising, the oceans are becoming more acidic, glaciers and polar ice caps are melting, sea levels are rising, the probability of severe weather events is increasing, food supplies are threatened, and weather-related natural disasters are becoming more frequent and more costly. But couldn’t those things be from natural causes? Couldn’t the scientists be wrong? Couldn’t it be too costly?

If your is answer “yes” to the above  or similar questions, then you probably have been influenced by propaganda created by the Climate Change Denial Machine. The Climate Change Denial Machine was patterned after the Tobacco Propaganda Machine and uses many of the same organizations and tactics. Almost  50 years after the Surgeon General announced that smoking had serious health consequences leading to premature death, many people still smoke, showing the effectiveness of the propaganda. The  Climate Change Denial Machine is much better funded,  supports a far greater number of science Skeptics and politicians, and has the Internet to widely disseminate its propaganda. While smoking only affected the smoker and those around them, climate change, if  left unaddressed,  will have serious consequences for everyone and everything on the Earth.

The workings of the  Climate Change Denial Machine have been explained in an article written by  Riley Dunlap and Aaron McCright, and their excellent diagram is shown below. It was published in Chapter 10 in the Oxford Handbook of Climate Change and Society, edited by John S. Dryzek, Richard B. Norgaard, David Schlosberg. It shows how money and misinformation flows from climate Skeptics and fossil fuel companies and is disseminated to the public. There is a link below the diagram to Chapter 10 of the Handbook if you would like to read the article .

The title has an “X”, as the number of years varies from 10 to 16 depending on who said it and when. I first heard this myth from George Will when he was attacking John McCain’s stand on global warming during the 2008 presidential campaign. Mr. Will claimed that the Earth’s temperature had not gone up in the last 10 years. When I contacted him for an explanation, he said that it was because 1998 was hotter than any year after that. Strangely, Mr. Will referred to the data from the World Meteorological Organization rather than that from NASA. Mr. Will has no use for the UN, but his statement could only be true if he used the UN data which showed that 2005 was slightly cooler than 1998. NASA’s data shows that 2005 was slightly warmer than 1998, and also that 2007 and 2010 were warmer yet. It’s a little hard to explain how the Earth reached those higher temperatures without  going up, but logic and truth are mostly irrelevant to those who say this.

As the years have gone by, “X” has been increased accordingly and the erroneous statement has been repeated on Skeptic’s blogs, newspaper articles, letters to the editor, op-ed pieces, sites like Yahoo!Answers, and by politicians such as Sen. Inhofe. The number “X” is now up to 16 and when I put “no global warming in past 16 years” in Google’s search engine, I got 114 million hits. It’s a great propaganda piece as it is simple, easily understood, and reduces people’s worry about climate change. Unfortunately, it is very comforting, and very, very wrong. The propaganda has been funded, circulated, and promoted by those who do not want us to address global warming as they have an economic interest in the issue.

So what is the truth of the matter? There are number of natural and man-made factors that affect the temperature of the Earth. The main factors are the amount of solar radiation we receive, volcanic activity, greenhouse gases, and ocean circulations such as El Niño and La Niña. Man’s main contribution falls in the area of greenhouse gases. We are now emitting 30 billion tons of carbon dioxide each year, and the atmospheric concentration of carbon dioxide has gone up about 40% in the last century. That increase and the ensuing feedback loops are the main factors that can be attributed to man. Though there are other contributions, most of the CO2 increase has come from burning fossil fuels.

Probably the best way to see man’s influence on the Earth’s temperature is to subtract out the factors that can be attributed to natural sources and to see what is left. That was done very nicely by climate scientist John Cook in a video which he produced and posted on YouTube. It’s only 2 minutes long, but it shows how the Earth’s temperature has responded to the increasing burden of carbon dioxide in the atmosphere.

It is important that we keep in mind those who are heroes and villains  in our efforts to protect the environment. Each year, this site takes a poll to find those most deserving of recognition in the Environmental Hall of Fame and the Environmental Hall of Shame. Nominations are now open for those  awards to those who have most affected the environment by words or action. With the ongoing  debate about  global warming and environmental regulations,  nominees should be easy to find.  Please send  at least one nomination  for  each category by e-mail through the “Contact” link or put it in the comment section . If you would, please include a short reason that your nominee should be chosen and suggest a suitable gift if they win.

Nominations will be taken until June 31st, 2013. The nominees will then be  listed  and this site will conduct a poll to determine the winner in each category.   You may suggest a suitable prize for your nominee. Please be imaginative, as particularly thoughtful or humorous  nominations will  be recognized and published on this site

The 2011 Environmental Hall of Fame Winners  was James Hansen for  playing a pivotal role in delaying a decision on the XL pipeline  whose construction  would greatly accelerate global warming. The 2011 Hall of Shame award went to Halliburton (Cheney),  for the Halliburton clause in the Clean Water Act. This clause provided a loophole that allows the composition of fracking chemicals to remain secret, thanks to Cheney. Past years winners and their gifts were:

“The authorities in New York are discovering what Egypt also learned — that it’s not as easy to regulate or arrest journalists when everyone is a journalist. But while that may make our lives a little more complicated, it is fundamentally a good thing for society,” writes Mathew Ingram in his post ‘What happens when journalism is everywhere.’

 I think Mathew uses the word ‘Journalism’ only because there is no other suitable description for world citizenry finding a voice and articulating independent views about the environment from a strong personal perception. This is one important node where social media branches off from the mainstream media, which in today’s world is a corporate institution. The Arab spring reporters reported with mobile phones, with no formal journalistic training and without financial incentive.

But this citizen reporting, whether or not you credit it with journalistic neutrality has come to be reckoned with a credibility that is almost undisputed now. This is deeply linked with a wave of neo-democratization that mainstream media is riding instead of refuting. For example, we see media offshoots like BBC’s User-Generated Content Hub, Reuter’s partnership with blogging network Global Voices, and sites like PJ Media .

In the sea of blogs that piece through world events with views ranging from practical to outrageous, there are few that are slowly but steadily debunking the myths of power and politics in determining our world views. J.C.Moore’s story is one such silent reconstruction.

J.C. Moore is a native Oklahoman who earned his Ph.D. in physical chemistry from Kansas State University. A retired professor of chemistry and physics, he is a member of the American Geophysical Union and Republicans for Environmental Protection. Dr. J.C. Moore is also a blogger who yielded key-board when people of his age and position would prefer spending time playing golf and not asking uneasy questions. He comes from the state whose legislature resolved to condemn invitation of Richard Dawkins by the University of Oklahoma because professor Dawkins is known for his stand against biblical genesis being taught as an alternative creation theory besides Darwinian Evolutionary theory in the state. J.C Moore also represents the same state that flaunts the Global Warming denier Senator James Inhofe – who recently proposed a law that would forbid funding for climate research.

Interested readers may find it worthwhile to check Dr. Moore’s blog JC Moore Online – a body of work that bespeaks of passion and rationality of appropriate mix. It’s not because I have been following his work for long now and come to respect his sincere efforts to engage Climate Change deniers with science and evidence, but because of his strength of conviction I find this man inspiring.

And such silent work should not go unnoticed for mostly the people for whom he is primarily concerned. Happily enough the review by Moore of Inhofe’s book ‘The Greatest Hoax’, a shorter version of which was also published in the Tulsa World recently became part of Senate debate between Sen. Bernie Sanders and Sen. James Inhofe, where Sen. Sanders quoted Moore’s lines to refute Sen. Inhofe’s views and policies. Here is the C-SPAN clip of Sen. Bernie Sander’s speaking.

This is citizen media at its best. It is inspiring to see my Think blogger colleague achieving something, which, considering his location and position corporate media will give a hand and a foot to do. And for J.C. Moore it neither takes fancy TV Channels nor high selling media campaign.

I missed the good fortune of interviewing Dr. J.C. Moore in person as we are half a world apart, but this is what he has to say about the above episode.

I wonder about what happens when there is one J.C.Moore in every society.

 An article has recently been circulating around the Skeptics’ websites called  “ Four recent scientific blows to the global warming theory”. They are hardly blows and they certainly cannot be called scientific, as they contradict scientific research. They do make you wonder where Skeptics get their misinformation. Lucy spilled the beans on that in one of the Peanut’s cartoons.

 Lucy: Charlie Brown, do you want to hear some little known facts of science?

 Charlie Brown, looking puzzled: Wait a minute, if they are so little known, how do you  know them?     

  Lucy: Because I’m the one who made them up.

Being a good scientist, Charlie Brown has a healthy skepticism toward Skeptics. And, no matter who made them up, he has found a little skepticism of the Skeptics is a good idea.

The Article starts: “The science behind the anthropogenic global warming theory appears to be falling apart with each new scientific study.”  “In fact, since the Climategate scandal broke, where top climate scientists were caught manipulating data to fit the theory, polls have shown the number of global warming believers has plummeted to new lows.”

Charlie Brown:  It’s strange that there are no references to those “new scientific studies”. Op ed pieces by skeptics, maybe, but no recent scientific studies or polls say that . Also, isn’t it time to give up on Climategate? Nine independent investigations into Climategate have found no scientific misconduct?

Article: It goes on, “Czech President Vaclav Klaus, an economist who lived through the rise and fall of communism, recently said that the climate change movement is a threat to democracy.” “I consider (the global warming doctrine) a new dangerous attempt to control and mastermind my life and our lives, in the name of controlling the climate or temperature.” And environmentalists “ don’t care about resources or poverty or pollution. They hate us, the humans. They consider us dangerous and sinful creatures who must be controlled by them.”

Charlie Brown: Wow! Dangerous and sinful? Few Skeptic’s articles are complete without quoting an obscure figure with bizarre views. Environmentalists do not want to control the climate or temperature; they would just like to keep it at a level comfortable for human civilization. And, aren’t they also “humans”?

Article: Blow 1., finally. “A biologist who claimed that polar bears were drowning because of melting ice has been suspended and is being investigated for scientific misconduct following his “veracity” in emotionalizing a debunked topic.  Get ready for Polarbeargate. “

Charlie Brown:  Polarbeargate? The Polar bear has become a symbol of all we may lose by failing to address our carbon emissions problem adequately. Skeptics can’t disprove the theory so they  to attack the symbol.  The scientist’s account of the polar bears drowning was a credible account of what he observed. The extent of the Arctic sea ice has declined about 30% since 1980. Polar bears now have to swim many miles to reach the sea ice to hunt. Those who don’t want to swim that far rummage around in the garbage dumps, leading Skeptics to believe that the bears are now more numerous.

 Dr. Monnett, a biologist studying Polar bear populations, counted four bears who had drowned trying to swim to the receding sea ice to hunt. Though that happened five years ago, the Interior Department was just recently put under pressure to investigate the matter by  Sen. James Inhofe who was unhappy that the bears were put on the threatened species list.   That was done, not because of Dr. Monnett’s work, but because the bear’s habitat is declining. As their habitat disappears, so will the Polar bear. There just aren’t enough garbage dumps to feed them all.

Article: Blow 2. “Today, new NASA data blows a gaping hole in global warming alarmism: NASA satellite data from the years 2000 through 2011 show the Earth’s atmosphere is allowing far more heat to be released into space than alarmist computer models have predicted, reports a new study in the peer-reviewed science journal Remote Sensing.”(sic?)

Charlie Brown: This is about an article by Roy Spencer, “On the Misdiagnosis Of Surface Temperature Feedbacks From Variations In Earth’s Radiant Energy Balance“, which claimed that climate scientists have the role of clouds wrong . It did not have enough scientific evidence to blow a hole in anything, but the article had a remarkable ability to “ shapeshift” as it sped around. It went from a paper published in a little-known journal where was not likely to be reviewed by climate scientists, to Roger Pielke’s website, where it was given a Skeptic’s A-OK. Then it went to the Heartland Institute, where senior fellow James Taylor fixed it up a little, classified it as a news article, renamed it “New NASA data Blow Gaping Hole In Global Warming Alarmism” and sent it on to Forbes. Apparently Forbes did not realize that describing scientists as “alarmist” 15 times was suspicious, perhaps because James Taylor is also on staff at Forbes as, get this, a “contributor on energy and environment issues”. From there it went on to Yahoo! News, most other major media sources, and dozens of Skeptics blog sites.

It was amazing that it became so distorted and widely circulated just three days after publication, before legitimate climate scientists had a chance to respond. When they did, they had some rather unkind things to say about the research. Trenberth and Fasullo soon summed it up: ”The model has no realistic ocean, no El Niño, and no hydrological cycle, and it was tuned to give the result it gave.The bottom line is that this paper has NO scientific merit” Later, A.E. Dessler analyzed Spencer’s paper in detail and published a rebuttal destroying Spencer’s arguments. The editor of Remote Sensing was so ashamed of the bad publicity that he resigned, saying” the paper should never have been published”.

Article: Blow 3. “The CERN physicists conducted a cosmic ray climate experiment that is said to directly contradict the climate change debate in the political arena.  Apparently, so much so that the scientists have been gagged from discussing their findings reportedly proving that cosmic (space-based) energy has a far greater effect on the climate than previously believed.”

Charlie Brown: Who said that? A book by perennial Skeptic Nigel Calder and Henrik Svensmark, The Chilling Stars,  claimed  the number of cosmic rays from the stars that strike the Earth is increasing. And, lead to more clouds since cosmic rays produce charged particles in the atmosphere that seed clouds. It’s an interesting theory, but the  data does not show that cosmic rays are actually increasing cloud cover. Also, there are plenty of particulates in the air to seed clouds and any effect from cosmic rays would be small in comparison.  ( See Blow 4., below.)

 The CERN scientists were not “gagged”, but they were asked not to report the results to the media before the formal paper was published. Perhaps they wish to avoid the type of outrageous publicity experienced by Spencer’s article.  Climate scientists are interested in the role that charged particles play so the scientists At CERN agreed to investigate the effect of cosmic rays on nitrate and sulfate aerosols.  After the experiment, the CERN cloud chamber was found to contain contaminates, so the experiment could not have proved or disproved anything. Except perhaps, considering Spencer’s paper, that climate Skeptics really don’t know clouds at all.

 Article: Blow 4. “A recent study published in the Proceedings of the National Academy of Science found evidence that coal burning plants may actually be cooling the planet. The findings have been accepted to the point of suggesting using sulfur to combat global warming; ‘Sulfur’s ability to cool things down has led some to suggest using it in a geo-engineering feat to cool the planet.’  If anything, this study proves that the science behind the anthropogenic global warming theory is unproven.”

Charlie Brown:  The particulates from power plants cause cooling, as well as cancer and lung diseases. Particles soon settle out of the airwhile the concentration of CO2 in the atmosphere keeps building up, warming the Earth much more than the cooling by the particles. We are now emitting 135 times as much CO2 as all the world’s volcanoes, but only about 7 times the particulates. The effect of particulates from volcanoes on the Earth’s temperature is well understood, so it is hard to see how this shows the “theory is unproven”.

The article concludes by noting that “the stakes are incredibly high” and then wanders off into some conspiracy theory. However, the stakes are high, and if we are not more skeptical of  the  Skeptics’ “little-known facts of science”, we are likely to find out just how high they are. Wouldn’t it be nice if the Earth stayed about the same for children in the future?

Every person in the world should be concerned about the effect of global warming on the world’s food supply. A good place to begin addressing the issue in the U.S. Congress. Congressman Lucas represents the 3rd district in Oklahoma and is Chairman of the Agricultural Committee. This summer, his district and the entire state of Oklahoma was under severe to extreme drought conditions. But it wasn’t just Oklahoma,  65% of the United States and many of the lands of the Earth where food is grown were also experiencing drought.  Food shortages abroad can pose humanitarian crises and national security concerns. Congressman Lucas has a responsibility to his district, to the United States, and to the world to protect our food supply. If you agree, then please sign the petition .

Congressman Lucas’ campaign ads point out he is trying to keep food prices affordable by opposing government regulation on the size of chicken cages. However, climate change is a much greater threat to food prices and to our food supply. Recent research has shown a direct link between climate change and the heat waves  and  droughts that we have been experiencing. Some may argue that more CO2 is better for plants, but no one doubts that extreme temperatures and droughts are devastating to the world’s food supply. A graph at the bottom of the article projects the  worldwide damage to food  production. As food production has fallen, shortages are beginning to occur, and prices are rising for food and animal feed. If you are worried about food prices, then please sign the petition.

Congressman Frank Lucas was asked at his town hall meeting if he would lead the Agriculture Committee in an investigation of the effect of climate change on our food supply. He said he would consider it, but over a year has passed and no investigation has been undertaken. Besides food prices, climate change will affect the availability of water and food in many parts of the world, particularly those most prone to drought and famine. In this century, water shortages, food shortages, and poverty related nutritional deficiencies will affect close to a billion people globally. We must start now to mitigate the effects of climate change in this century – and the Agricultural Committee is the most important place to start. One voice may be ignored, but a million requests will be heard. Please ask Congressman Lucas to investigate the effect of climate change on our food supply by signing the petition.

Whenever a newspaper reports on an article that confirms man’s role in global warming, a number of outraged citizens usually proclaim on the newspaper’s blog site that the article is wrong. When asked for their source, they often list Wattsupwiththat, Anthony Watt’s blog site.

One recent newspaper article reported on the BEST study, done by a team of climate skeptics funded by Koch industries and led by Dr. Richard Muller, a noted climate skeptic. Dr. Muller’s team analyzed 1.6 billion temperature records in an effort to prove climate scientists wrong. But they didn’t, and Dr. Muller acknowledged it. He reported that global temperatures were probably higher and man’s role was likely greater even than that reported by climate scientists. He also found that the temperature station data, often criticized by skeptics, was accurate – and that the only credible explanation for global warming is the increasing atmospheric CO2 from man’s activities. The  summary of the paper describing the work is now available.

It would seem rather hard to refute Dr. Muller’s work, but one citizen claimed that there was a peer-reviewed journal article that showed that Dr. Muller was wrong. His source was Wattsupwiththat, which did not exactly claim it was peer-reviewed, but certainly left that impression. Here is what it said: “From the told ya so department, comes this recently presented paper at the European Geosciences Union (EGU) meeting. Authors Steirou and Koutsoyiannis, after taking homogenization errors into account find global warming over the past century was only about one-half [0.42°C] of that claimed by the IPCC [0.7-0.8°C].”

However, that isn’t the whole story. The paper was a conference contribution based on a graduation thesis which was submitted to the EGU session, “Climate, Hydrology and Water Infrastructure”. The abstracts are not peer-reviewed and most of Watts’ data was taken from the slides which are also not peer-reviewed. The paper was presented in the wrong session where it was not likely to be heard by experts in the field. There actually was a session on “Homogenization of Data”. An EGU member in attendance noted the paper had errors, and commented, :” It would have been better if this abstract was sent to the Homogenisation Session at EGU. This would have fit much better to the topic and would have allowed for a more objective appraisal of this work. Had I been EGU convener of the Homogenization Session, I would probably have accepted the abstract, but given it a poster because the errors signal inexperience with the topic and I would have talked to them at the poster.” That hardly refutes Dr. Muller’s work.

Another newspaper aticle reported that a link had been shown between extreme temperatures and global warming.  In the past, climate scientists could only say that climate change was increasing the probability of severe weather, heat waves, and droughts. However, a recent paper by James Hansen et. al. established that the probability of extremely hot temperatures, worldwide, is now 10 times as likely as in 1980. Not only did the paper establish a definite link between climate change and extreme temperatures, but the paper was a straightforward statistical analysis that did not rely on theory or climate models. It would seem that that would be difficult to assail.

However, when it was published in the newspaper, a blogger claimed that there was a research paper that disproved the findings, and the trail led to an article  on Wattsupwiththat, panning Hansen’s paper . It referred to an article, Climate Distortion, by Cliff Mass which states, “Their conclusions are demonstrably false and their characterization of the science and statistics are deceptive at best.”  In his article, Mr. Mass  argued: “Now as the earth warms up the temperature variations shown remain like the bell curve…or Gaussian, but the mean should shift to warmer temperatures (see the figure below). The result is that you get more warm extremes and less cold extremes (less cold extremes are not mentioned very often for some reason).”

That would seem reasonable, as an increase in the mean would shift the distribution to the right, meaning more extremely hot temperatures. However, he somehow used this to claim Hansen was wrong. His argument is not clear, and it is certainly wrong, as he ignores the possibility that the variance could change, which would broaden and flatten the distribution. From Hansen’s paper, here is the distribution based on the actual data:

As you can see, the two graphs are quite different. Dr. Mass*, who is  a Professor of Atmospheric Sciences at the University of Washington , does not accept the conclusions of most other climate scientists, and prefers to assign most of global warming to natural variability, a view that Hansen disproved in his paper. Dr. Mass is known for making controversial statements, and though he volunteered his time at for several years as a TV weatherman, he was released for making controversial statements. Mr. Mass apparently rejected Hansen’s paper, as he does not comment on the correct distribution – or that the paper mentions extremely cold temperatures. Climate Skeptics often argue that an extremely cold weather event disproves global warming. However, a similar distribution for the winter months (see paper) shows a significant probability of extremely cold weather events, even though global warming is occurring – meaning the skeptics argument is baseless.

So, Mr. Watts claims a student paper with errors, presented in the wrong session, and is in no way peer reviewed, invalidates two years of work done by a team of climate scientists. You would think that one could not inflate a paper more than that, but actually it can be done. And, Mr. Watts achieved that by promoting Dr. Mass’ article.

A large body of scientific evidence, going back to the middle of the 19th century, links the concentration of atmospheric carbon dioxide,  the temperature of the Earth, and the Earth’s climate. Those who study the Earth and its ecosystems have found ample evidence that the climate is changing. The USDA recently acknowledge that fact by shifting the plant hardiness zones for gardeners northward, acknowledging that frosts occur later in the fall and the last freeze in spring occurs earlier. However many people still doubt climate change and point to weather events as evidence.

Theory: Climate scientists would like to clearly establish the link between climate change and extreme weather events, but that is difficult because of the natural variability of the weather.  The link between global warming, heat waves and droughts would seem unquestionable, but it is difficult to prove. Global warming has increased the energy and moisture in the atmosphere, making conditions for severe storms and floods more likely.  In the last century, the Earth’s average temperature has increased by about 0.8°C, increasing the amount of water the air can hold by about 7%.  It is a reasonable conclusion that when it rains, it will rain more and when it snows, it will snow more. So strangely enough, global warming could actually lead to greater snowfall.  (1) However, it has been very difficult to prove, and certainly even more difficult to convince skeptics that that might be the case.

Climate Models: Another approach to linking extreme weather events to global warming has been through the use of climate models. The models take into account the factors that influence climate and weather, and are often used by meteorologists for “future casting” the weather for 10 day forecasts, which is about as long as normal weather patterns last. However, the models may also be used to examine the effect of global warming on the weather events. The models are used to compare the prediction for a weather event assuming that there is no global warming with a prediction of the weather event that includes global warming. In many cases, it can be shown that the weather and rainfall will be more extreme under the global warming conditions. The results are often challenged by climate Skeptics, who claim that the models do not accurately represent the data, or that the models are “falling apart”. The models were developed to fit a century’s worth of the weather and climate data, and there is little evidence to support the Skeptics claims. However climate scientists would like to show a definite link between global warming and weather events to silence those criticisms.

Statistical Evidence: A recent NOAA report, edited by Petersen, et al. (2) , examined 6 extreme weather events that occurred in 2011 and found that there was a link between climate change and the extreme weather event. One of the most interesting reports (3) ,  found that the 2011 heat wave and drought in Texas were 20 times more likely to happen than they would have been in the 1950’s. How did they arrive at that conclusion? A recent paper by Hansen et al.  (4), shows that extreme temperatures are much more likely to occur worldwide than in the 1950’s, and over 10 times as likely to occur as in 1980. As Hansen puts it, the extreme temperatures “which covered much less than 1% of Earth in 1950, now typically covers about 10% of the land area. It follows that we can state, with a high degree of confidence, that extreme anomalies such as those in Texas and Oklahoma in 2011 and Moscow in 2010 were a consequence of global warming because their likelihood in the absence of global warming was exceedingly small.”

Those two papers are important as they have been able to establish a quantitative link between the probabilities of weather events and global warming. More importantly, the link does not depend on theory or on climate models, and relies only on a straight forward statistical analysis of the data. The method depends on computing the normal distribution of the Earth’s temperature anomalies for each decade and then comparing how the distribution of extreme weather events change with time.

Normal distributions:  Before examining how the method works for weather events, it might be useful to examine how it works with something more familiar, like the height of American men. How could we show whether the number of extremely tall men was increasing as time went by?  This could be done by taking a representative sample of men and examining a graph of the normal distribution. We could find the average, μ , and then repeat the process every 10 years to see how the average changed with time. An increase in the average height might indicate that there would be more extremely tall men, but that is not the full story.

Another piece of information that needs to be considered is the variance, or how widely the height of men vary about the mean. The variance is usually measured by the standard deviation , σ, which can be easily calculated from the measurements done to compute the mean. A  graph of the normal distribution  is shown at the right.  “Normal” means that the data has been divided by the total number of men in sample, so that the area under the entire curve represents 100%. That feature is very useful for comparing heights, and it also allows us to associate an area under the curve with  probabilities.

The average height, μ on the graph, is 5’10”, and the standard deviation, σ, is 3 inches. About 95% of the sample falls within 2 standard deviations of the mean, which also says that the probability is 95% that a man selected at random would fall between 5’4″ and 6’4″. Those over 2σ  from the mean, or 6’4″, make up about 2% of the sample and are considered very tall. Finally, those over 3σ  from the mean , over 6’7″, are considered extremely tall and make up only 0.15 %. Michael Jordan and a host of other National Basketball Association players fall into that 3σ category.

How would it be possible to tell whether the incidence of extremely tall men is increasing? One way would be to take height data collected every 10 years, plot the normal distribution, and see how the area of the graphs out past 3σ change. We could not only tell whether there were more extremely tall men, but we could calculate how the probability of finding an extremely tall man changed, just by comparing areas on the graph.

Weather events. Enough data and computing power is now available to calculate normal distributions of temperature data every 10 years for many decades. Having the normal distribution of the temperature data by decade can be used to find whether the probability of extreme temperatures is increasing or decreasing. The Earth’s temperature was fairly stable from about 1950 to 1980, making it a convenient standard for comparing changes. Rather than using temperatures, the graph uses temperature anomalies, which measure how far a temperature reading was above or below average. 

The procedure is similar to the one described for examining the height of men. Hansen, et al. used the Earth’s temperature data to graph normal distributions of the Earth’s temperature anomalies by decade, from 1950 to the present. They found that the distribution of temperature anomalies approximate a normal distribution. 

The results of their work for the summer months show that beginning in about 1970, the mean begins to move to the right toward higher temperatures. It can also be seen that the variance of the data increased and shifted to the right, showing that the probability of extreme temperatures increase greatly from 1950 to 2011.  It can be seen that the number of extreme temperatures, those out past 3 ( meaning 3σ), almost nonexistent in the 1950s, have grown significantly larger in each decade after 1980. A similar graph, using  σ for the last 30 year period (not shown), found the probability of temperatures past 3 sigma is 10 times as great as for the 198o2 to 2010 years.

It should also be noted that the left side of the graph flattens, but that the probability of extremely cool temperatures is not zero. Though  hot temperatures became more probable, that there was still a significant likelihood of cooler temperatures.

Climate Skeptics often argue that an extremely cold weather event disproves global warming. The normal distributions by decade for the winter months is given at the right.  The graph shows the average winter temperatures have increased significantly during the last 30 years and the variance in the temperature has become greater as time progressed. However, the left side of the graph shows there is still a significant probability of extremely cold weather even though global warming is occurring. This means that the skeptics argument is baseless. It is also sometimes argued that extreme snowfalls disprove global warming, but that is also a baseless argument. Extremely cold air can hold little moisture, and it is warmer air, slightly below freezing, that produces the greatest amount of snow. The Inuit know that a warm spell brings a much greater chance of snow.

So there we have it. Climate physics predicts that global warming should cause higher incidences of extreme weather. Climate models find that global warming makes increased rainfall and storms more probable. A straightforward statistical analysis of temperature data not only shows that extreme temperatures are more likely, but has allow climate scientists to calculate how global warming affects the probability of extreme temperatures. A definite link between global warming and extreme weather has been established by the research.
