The Climate Change Denial Machine

Thu ,31/01/2013

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 .

Climate Change: Citizen Journalism Can Make a Difference

Mon ,03/12/2012
 This is a guest article by Pabitra Mukhopadhyay about citizen journalism which was first published on his website, Pabitraspeaks.  It is great honor that Pabitra chose this website as an example of citizen journalism. Pabitra’s posts and articles on Climate Himalaya, Th!nkaboutit.eu, and his website, Pabitraspeaks, show that he is a citizen journalists of the first order, concerned about his fellow man and a sustainable environment.
 
 
“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.

Petition: Congressman Lucas, Protect Our Food Supply

Fri ,07/09/2012

 

 

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.

Climate Skeptic Article Inflation: Wattsupwiththat?

Tue ,04/09/2012

 

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 paper has not yet been published but the work is available online and a press release describing the work is 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.  

* Note on 09/05/2012. The original version of this article did not  give the full credentials of Dr. Mass and the article has been updated with the correct information. Please see the comments for a discussion of this issue.

C-SPAN Video: Sen. Bernie Sanders Quotes This Website in Debate with Sen. Inhofe

Mon ,06/08/2012

Some time ago, the author posted a review of Sen. Inhofe’s book,” The Greatest Hoax” and the Tulsa World published a shorter version of the review. Recently, Sen. Bernie Sanders used quotes from the book review in a Senate debate with Sen. Inhofe. You may find a C-SPAN clip of Bernie Sanders comments below:

Recent research has linked the heat waves, droughts and wildfires we have been experiencing to climate change. It is imperative that Congress take action to mitigate the damage we are doing to the environment. Please contact your representatives about this issue.

Bits and Pieces 15: Is Climate Change Threatening Our Food Supply?

Mon ,23/07/2012

The Palmer Drought Index has been used since 1890 to measure drought conditions on a scale of zero (normal rainfall) to -4 (extreme drought).

 

If you agree that  it is, then please sign the petition below, urging Congress to act.

The author asked Congressman Frank Lucas at his town hall meeting last May if he would consider investigating the effect of climate change on our food supply. Congressman Lucas said he could not commit to it, but he would consider it. However, more than a year has passed and an investigation has not been undertaken. Recently, 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.

Heat waves and droughts are becoming increasingly common and are greatly affecting food production and food prices.    During the last 30 years, the Palmer Drought Index, which measures drought severity has fallen as low as -2.2 for the latitudes at which crops are grown. That is  much, much lower than even the dustbowl days.  This is serious. Currently, 64% of theUnited States is under drought conditions. This year’s corn crop is expected to be 10% less than last year’s, which  is  driving up the price of food products and animal feed.  A round bale of hay, normally $20, may be as high as $100 next winter. Last year’s droughts and heat waves reduced the cattle herds by over 3 million animals, and many ranchers are now selling off part of their herds so they can afford to feed the rest next winter. This has kept prices low for now, but the effect will be seen later in the year.

In the past, climate scientists could only predict that climate change was increasing the probability of severe weather, heat waves, and droughts – but they now have enough data and computing power to estimate the probability of extreme weather events. Recently  Stott, et. al.  found that, due to global warming, the heat waves and droughts in Texas and Oklahoma last year were 20 times more likely to happen than in 1950. . Research by Hansen et. al. found the probability of extremely hot temperatures are now 10 times as likely as in 1980. That means that extreme temperatures that affected less than 1% of the landmass in 1980, now affect almost 10% of the landmass annually. What we are experiencing now, will likely be the norm for the future.

If you are concerned about food prices and the future of our food supply, please click on this link, petition on signon.org  , to sign the petition urging Congressman Lucas to lead the Agricultural Committee in an investigation of the effect of climate change on our food supply. Then, please forward a link to the petition to your friends and contacts.

Gaming the Peer Review System : Part 1. Biased Editors

Sun ,22/01/2012

If I have seen further it is only by standing on the shoulders of giants. … Sir Isaac Newton

 Peer review:  Every scientist’s work depends upon the evidence and reasoning of all the scientists who preceeded him. To ensure that previous work is reliable, scientific journals have established a peer review process to ensure that published papers are free of errors in reasoning and methodology. Normally,when a paper is submitted for publication, the editor of the journal removes the name of the author and sends the manuscript to a number of experts in the area for review. The editor keeps the names of the reviewers confidential. In case an error is found or corrections suggested, the reviews are returned to the author with suggestions for improvement. When the reviewer’s concerns are addressed to the editor’s satisfaction, the article is published. It is a good system for ensuring the quality of research publications, but in a few cases ways have been found to game the system.           

Biased Editors: The editors of journals published by major science organizations are chosen for their expertise in the area and for their fairness. However, any organization may publish a journal and claim their articles are peer-reviewed.  For example, a recent op Ed article in the Tulsa World claimed “Climate predictions must be science-backed“. That’s certainly true, but the author claimed his opinion was backed by a “a peer-reviewed article based on NOAA  data which proves that CO2 may not be the cause of global warming.”  However, no peer reviewed article reaching that conclusion could be found. When I contacted the author for his source, he referred me to an article by Ferenc Miskolczi published in Energy and Environment. Though Miskolczi’s article is based on NOAA’s data, it finds that adding CO2 to the atmosphere does not change its spectroscopic properties – a conclusion violating the laws of physics. Miskolczi’s article was criticized by van Dorland and Forster, who wrote: “Miskolczi (2010) theorizes that atmospheric CO2 increases cannot be a cause of global warming. We show his theory to be incorrect both in its application of radiation theory and from direct atmospheric observations.” How did such a paper get published?

The editor of a journal is almost completely responsible for seeing that articles are properly reviewed and for deciding if they should be published. Sourcewatch says that Energy and Environment is a peer-reviewed social science journal published by Multi-Science and the editor is Sonja Boehmer-Christiansen, who is described as a reader in geography. Many climate change skeptics such as Sallie Baliunas, Patrick Michaels, Ross McKitrick, Stephen McIntyre, Roger Pielke Jr., Willie Soon, and  Steve McIntyre publish articles there that would not be accepted in major journals. Sourcewatch says the editor admits in an article published online that “the journal I edit has tried to keep this debate [climate scepticism] alive”. She also states “I’m following my political agenda — a bit, anyway … But isn’t that the right of the editor?”

Not really, if you want to claim to be a peer reviewed science journal.

Dr. Heidi Cullen: The Weather of the Future

Sun ,13/11/2011

What will the weather be like in the future? Dr. Heidi Cullen, noted climatologists and author of the book, The Weather of the Future , gave a public talk in Tulsa explaining how global warming is causing the weather to be more extreme. She explained that our future holds an increasing number of extreme weather events unless we act to reduce our carbon emissions.  There was an article in the local Tulsa World newspaper announcing the talk; however,  there was no follow-up article describing the talk or her research on climate change. Tulsa Oklahoma was once considered the oil capital of the world and many of the local politicians and oil company executives that live there do not have a favorable opinion of climate change, so her message was one many Oklahomans needed to hear. To correct the newspaper’s oversight, the author sent the following letter to the editor, which outlined the main points of her talk. The letter generated some controvery and there were a number of comments on the letter.

In her talk, Dr. Cullen explained how global warming is changing our climate. Climate describes the average weather, and research shows the Earth’s average weather has been changing. It is difficult to recognize the pattern of change and only by analyzing millions of weather and temperature records is it possible to see the pattern. Over the last century, NASA’s temperature records show that the Earth’s temperature has increased by about 1°F. That has increased the energy in the atmosphere and the moisture in the air over the oceans. That combination is causing our weather to become more extreme, as you have probably noticed from the events that have happened lately.

Dr.Cullen explained that climate is complex, made up of both natural and man-made factors, and the scientific research has been directed toward identifying the contributions of each. Carbon dioxide was identified in the 19th century as one component of the atmosphere that helps warm the Earth. Our activities have increased the CO2 concentration in the air by 37% since then, and undoubtedly much of the recent warming has been caused by man. Detailed studies of extreme weather events have shown that global warming contributed to their severity. Although that may seem bad news, the upside of that is that if we are responsible for it, we can change it.

The first step in that process is to immediately begin to reduce our carbon dioxide emissions from fossil fuel energy sources. Dr. Cullen outlined what our energy needs will be by 2050 and showed how we can reduce our carbon emissions and meet our energy needs by then with mostly renewable sources. She explained that building the infrastructure for renewable energy will create jobs and contribute to our economy. Rather than considering the cost of doing so a mortgage on future generations, we should consider reducing pollution and developing sustainable energy sources as an investment in our future.

Bits and Pieces 11: The Arctic Sea Ice Is Disappearing

Fri ,23/09/2011

 

   It is hard to deny that the Earth is warming when you look at its effects on the Arctic sea ice. There are still a few people who will not admit that the Arctic sea ice is disappearing. Here is the data in graphic form and the pictures that show that between 1979 and 2010, about 40% of the Arctic sea ice has disappeared.
 

Global Warming in Pictures

Thu ,01/09/2011

Science is about using observation and reason to understand the physical world. Some people are suspicious of computer models and theories; so here is the basic data about global warming in pictures and graphs.

Ice Ages: In the past, the Earth’s temperature has varied from the Ice Ages to the much warmer temperatures of the interglacial periods.  Ice core data gives a good picture of what has happened to the Earth’s temperature in the last half million years, as shown by the blue line. The changing temperatures are attributed to the Milankovitch Cycles, small variations in the Earth’s orbit that cause the Earth to receive different amounts of sunlight. The Earth becomes slowly warmer during the periods where the solar energy increases. As the Earth begins to be warmed by sunlight, CO2 becomes less soluble in the ocean and the CO2 concentration in the atmosphere increases, which further amplifies the warming since CO2 is a greenhouse gas.

As you can see in the graph, the red line shows how intricately the CO2 concentrations and temperatures are related. The CO2 concentration drops to about 180 ppm during the glacial periods and rises to about 290 ppm during the warmer interglacial periods. As the far right of the graph shows, we are now in an interglacial period that began about 6000 years ago. The Milankovitch Cycles predict that Earth should slowly cool for the next 20,000 years, but it is warming instead.  Please note that the concentration of CO2 did not rise above 300 ppm in any previous warmer periods but on the far right side of the graph, the red line indicating the CO2 concentration is now approaching 380 ppm. http://www.daviesand.com/Choices/Precautionary_Planning/New_Data/IceCores1.gif

Current CO2 Levels: In the past, the warming oceans released the CO2 as a natural process. However, man is now putting about 30 billion tons of carbon dioxide into the air each year. Much of it stays there and the Keeling curve below shows how CO2 is building up in air. What might that mean for man? In 2011, the CO2 concentration reached 387 ppm, far higher than it has been for perhaps 15 million  years.

  

 This article explains what the Earth may have been like then: ”The last time carbon dioxide levels were apparently as high as they are today — global temperatures were 5 to 10 degrees Fahrenheit higher , the sea level was approximately 75 to 120 feet higher, there was no permanent sea ice cap in the Arctic, and very little ice on Antarctica and Greenland.”

 

Earth’s Temperature: Carbon dioxide is one of the greenhouse gases that warm the Earth. NASA’s graph below shows how its increase is changing the Earth’s temperature. Though the Earth’s mean temperature varies widely from year to year, the graph on the right is a moving average that allows you to see the trend in the temperature much easier.

                                                           htp//data.giss.nasa.gov/gistemp/2010november/fig2.gif

  The effect of particulates, which cool the Earth, can be seen around 1991 when Mount Pinaturbo exploded. The flat place in the graph from about 1940 to 1970 is attributed to particulates generated by World War II, atmospheric atomic bomb testing, and postwar industrialization – before particulate emissions were regulated. Clearly, the Earth is getting warmer.

Record Temperatures: Nine of the 10 hottest years on record occurred in the last decade. The other record-breaking year was 1998. the chart gives the record temperatures for 50 years and the inset for the last last 160 years.

This has led to extreme heat waves  in areas such as Moscow.

Effect on the Weather:  According to NOAA, global warming is affecting the El Niño and La Niña ocean currents cycles which affect  the weather patterns in North America.  The cycles are occurring at higher temperatures and are becoming more unpredictable . Changes in ocean currents may be a major tipping point in climate change.

Enso-global-temp-anomalies

Effect on the Earth: Scientist tell us that the increasing CO2 concentration is leading to a warmer Earth, more extreme weather, melting glaciers and polar ice, crop failure, droughts, and wildfires. We have certainly experienced many of those things recently, which should make us think about what effect our activities are having on the Earth. Many of the changes in the Earth are subtle, but here are two of NASA’s pictures that clearly show how the Earth is changing. Between 1979 and 2010, about 30% of the Arctic ice has disappeared.

Current Sea Ice

 This has greatly affected the way of life of the native Inuit who live and hunt on the Polar ice.  While they may adapt, their way of life and culture which sustained them for centuries will be destroyed. The Polar bears, uniquely adapted to live in on the Polar ice, have been put on the threatened species list because their habitat is clearly declining.  As their habitat disappears, so will be the Polar bear. It is something man should think about – as our habitat is deteriorating, also.

 Note: This was posted on 09/01/2011 and updated on 03/06/2013 to include data that was not presented in this more comprehensive collection of pictures and graphs of global warming data.
