What is the truth about anthropogenic global warming<\/a>? Is global warming caused by humans?<\/p>\n\n\n\n

These questions have been part of the climate change debate<\/a>, especially since the 1992 Rio Conference. Some people and organizations see their agenda or ideology at risk, so they seek to discredit science that points to climate change\u2014and anthropogenic global warming in particular. Historians Naomi Oreskes and Erik Conway discuss this in their book Merchants of Doubt<\/em>.<\/p>\n\n\n\n

Read more to learn about the debate surrounding the issue of anthropogenic global warming.<\/p>\n\n\n\n\n\n\n\n

Taking on Anthropogenic Global Warming<\/h2>\n\n\n\n

In June 1992, the U.N. held an Earth Summit to address what to do about climate change. The MOD’s techniques were working and President Bush only decided to go at the last minute. The conference produced a Framework Convention that 192 countries signed, committing to preventing dangerous anthropogenic activity. <\/strong>The Framework didn\u2019t include any emissions limits; however, it was just a principle.<\/p>\n\n\n\n

Further Exploration of the Science<\/h3>\n\n\n\n

By 1992, it was clear that global warming was real and happening now. The only major to-do was to prove that it was caused by humans\u2014if it was, contrary to what the MODs claimed, there was definitely something we could do to slow or stop it. <\/strong><\/p>\n\n\n\n

To prove that humans were causing global warming, scientists looked for ways in which anthropogenic global warming was distinct from other causes of warming. This approach was called \u201cfingerprinting\u201d or detection and attribution.<\/p>\n\n\n\n

A possible fingerprint of greenhouse gases was the temperature of all the layers of the atmosphere.<\/strong> If the sun was the source of warming, since it was outside the atmosphere, the entire <\/em>atmosphere should warm. If greenhouse gases were the source, however, only the lower atmosphere (where the gases trap heat) would warm up. The outer layers of the atmosphere would actually cool <\/em>because less heat than usual was making its way through the inner layers to the outer. (In Chapter 7, Singer brought this up when doubt-mongering ozone depletion.)<\/p>\n\n\n\n

Climate scientist Benjamin Santer began looking at the vertical structure of the atmosphere. He had worked on checking the accuracy of climate models<\/a> as a student, and he learned about fingerprinting at one of his first jobs. In 1994, the International Panel on Climate Change (IPCC) asked Santer to be the convening lead author for Chapter 8 of their next (second) assessment. <\/strong>The IPCC wasn\u2019t very prestigious at the time but Santer agreed after some convincing.<\/p>\n\n\n\n

International Panel on Climate Change (IPCC) Second Assessment<\/h3>\n\n\n\n

Santer\u2019s job would be to organize a chapter about fingerprinting based on available information\u2014basically, coordinate the writing and put together everyone\u2019s individual parts. His chapter had 36 authors and they met in August 1994 to start work.<\/p>\n\n\n\n

In October and November, Santer went to the first drafting session, where all the lead authors of the entire report met. The first hiccup was whether to discuss the uncertainty of the model and observations in Chapter 8. Uncertainty was already covered in other chapters, but Santer wanted to include it in Chapter 8 as well<\/strong> because readers might not read the report in full, and Santer had no say in how it was discussed in other chapters. Santer got his way and his chapter would also include a discussion of uncertainty.<\/p>\n\n\n\n

Next was the first round of Chapter 8\u2019s peer review.<\/strong> Approximately 20 detection and attribution scientists, everyone who had participated in writing the chapter, and all the other chapters\u2019 lead authors reviewed Santer\u2019s chapter.<\/p>\n\n\n\n

In March 1995, there was a second drafting session, and in May, the whole report and policymakers\u2019 summaries went to reviewers selected by the governments who were members of the IPCC. <\/strong>Santer also sent his work to Nature<\/em> around the same time for review.<\/p>\n\n\n\n

In July 1995, there was a third drafting session. Santer hadn\u2019t received the government reviewers\u2019 notes yet (he had been chosen as the lead author later, so the other chapters were further along), so he presented his unreviewed <\/em>results. He and his team had been working on the vertical structure of the atmosphere and might have proved that humans had changed the climate.<\/strong><\/p>\n\n\n\n

In September 1995, the whole report was leaked and Santer\u2019s chapter made the news, though the <\/strong>New York Times<\/em><\/strong> didn\u2019t quite get the story right.<\/strong> It reported that scientists had just now started to think human activity was likely a cause of global warming. In reality, scientists had thought it was likely for years and had just proven <\/em>it. <\/p>\n\n\n\n

The MOD’s Response<\/h3>\n\n\n\n

Proof of anthropogenic global warming was bad news for the MODs. In early November 1995, the Republican majority in Congress held hearings in which they questioned the science. One of the witnesses, ozone-depletion denier and climatologist Patrick J. Michaels explained that the IPCC had gotten it wrong because the model predictions didn\u2019t match the observed temperatures measured by NOAA weather satellites.<\/strong> He\u2019d mentioned this in his peer review of the report but the IPCC had ignored him.<\/p>\n\n\n\n

Witness Jerry Mahlman, a NOAA scientist, explained that the model didn\u2019t match the observed weather data because it wasn\u2019t supposed to.<\/strong> The model deliberately ignored the effects of the sun or volcanic dust because the point was to isolate the effect of CO2<\/sub>. However, the satellites measured real life, which included the sun and volcanoes, so obviously the temperatures were different. The model and observations weren\u2019t looking at the same thing, so it didn\u2019t make sense to compare them.<\/p>\n\n\n\n

The hearing didn\u2019t get much media attention (everyone knew the Republicans opposed environmental action by now), but it did reinforce Republicans\u2019 confidence in doing nothing.<\/strong> <\/p>\n\n\n\n

Further Exploration of the Science<\/h3>\n\n\n\n

In November 1995, there was a final IPCC plenary session. At this meeting, Santer received the government reviewers\u2019 comments. When Santer presented his results, two government representatives immediately opposed his chapter (Saudi Arabia and Kuwait) and one delegate (Kenya) thought the report shouldn\u2019t even cover fingerprinting.<\/strong><\/p>\n\n\n\n

The IPCC chairman put together a drafting group to revise the chapter and sort everything out. The drafting group included the lead authors, delegates from other countries, and the delegates who had opposed the chapter (except the Saudis didn\u2019t send anyone). When Santer shared the revised chapter, the Saudis still didn\u2019t like it.<\/strong> <\/p>\n\n\n\n

The group put the discussion on hold to finish the Summary for Policymakers. There was disagreement here too\u2014everyone had different opinions about the adjective used to describe the anthropogenic influence on climate. After trying almost 30 words, they ultimately settled on \u201cdiscernable.\u201d<\/p>\n\n\n\n

Santer coordinated implementing the changes requested from the plenary. The major change was organizational\u2014all of the other chapters in the report had summary statements at the beginning, but Chapter 8 had statements and the beginning and end, so the chairman told Santer to take out the statement at the end of his chapter.<\/p>\n\n\n\n

The MOD’s Response<\/h3>\n\n\n\n

The response of the merchants of doubt<\/a> came quickly.<\/p>\n\n\n\n

Writing to Science<\/em><\/h4>\n\n\n\n

In February 1996, before the third IPCC assessment was released, Singer published a letter in <\/strong>Science<\/em><\/strong> that claimed:<\/p>\n\n\n\n

  • Some satellite data had shown no warming and actually showed cooling, so the models were wrong.<\/strong> (This claim was unsupported by data\u2014the models and satellite matched. There were<\/em> differences between satellites and balloon instruments, but that was normal because they were in different locations and didn\u2019t measure the exact same things.)<\/li>
  • The fingerprinting work shouldn\u2019t have been included because it hadn\u2019t been peer-reviewed yet,<\/strong> and doing so violated IPCC\u2019s rules. (The IPCC rules allow the inclusion of non-peer-reviewed materials as long as the IPCC peer reviewers have access to the same material. This is so that the report uses the most current information. Additionally, the specific study Singer mentioned was<\/em> peer-reviewed.)<\/li>
  • The panel ignored a U.S. government report<\/strong> that concluded warming might be only half a degree Celsius. (This report wasn\u2019t cited.)<\/li>
  • The IPCC had called climate change \u201cthe greatest global challenge facing mankind,\u201d which Singer felt was unreasonable.<\/strong> (No IPCC documents contained the phrase Singer quoted. In fact, the IPCC avoids extreme and alarming statements\u2014remember the argument over \u201cdiscernable.\u201d)<\/li><\/ul>\n\n\n\n

    Tom Wigley, one of the Chapter 8 authors, responded, debunking everything. Singer\u2019s only response was to provide the missing citation.<\/p>\n\n\n\n

    Accusations of Secret Edits<\/h4>\n\n\n\n

    In May 1996, before the IPCC report was published, Santer and Wigley gave a briefing on Chapter 8 on Capitol Hill. An industry lobbyist and representative of the American Petroleum Institute accused them of secretly editing the report.<\/strong> Santer did <\/em>make changes after the plenary session to address the discussion, government comments, and structure, as requested. But the MODs accused him of cutting out sections about uncertainty and ignoring other scientists\u2019 dissent.<\/p>\n\n\n\n

    The Global Climate Coalition (an industry group) attacked the IPCC and put out a report called \u201cThe IPCC: Institutionalized Scientific Cleansing.\u201d<\/strong> Nierenberg received a copy and in an interview, repeated its claims even though they were impossible to verify (the report hadn\u2019t been published yet, so there was no way to compare older drafts to the final one to see if anything really had been cut). Nierenberg also claimed the IPCC had cut out bits about uncertainty, which was a lie\u2014Santer had insisted on including a discussion of uncertainty in his chapter back in the first drafting session.<\/p>\n\n\n\n

    Fred Seitz continued the attack\u2014in June 1996 in the Wall Street Journal<\/em>, Seitz accused Santer of making unauthorized changes and corrupting the peer review process<\/strong>. He suggested finding a more reputable authority than the IPCC because they couldn\u2019t follow their own rules.<\/p>\n\n\n\n

    Setting the Record Straight<\/h2>\n\n\n\n

    Santer and 40 cosigners wrote to the <\/strong>Wall Street Journal<\/em><\/strong> to explain what had really happened<\/strong>\u2014the IPCC chairman told him to make changes and this was normal\u2014it\u2019s how peer review works. The only differences between the IPCC review and standard peer review were:<\/p>\n\n\n\n

    • The reviewers weren\u2019t all scientists; some were government representatives.<\/li>
    • Santer made the changes later in the process than usual because he didn\u2019t receive the reviewers\u2019 comments until later. <\/li><\/ul>\n\n\n\n

      Santer also pointed out Seitz couldn\u2019t back up his claims\u2014he hadn\u2019t had anything to do with the report and he wasn\u2019t a climate scientist.<\/strong> The Journal <\/em>initially refused to publish Santer\u2019s explanation. It finally did, but only after editing it and cutting the names of the cosigners. The IPCC chairman and Bert Bolin also wrote the Journal<\/em>, and it edited their letters too.<\/p>\n\n\n\n

      The University Corporation for Atmospheric Research and American Meteorological Society boards republished the unedited versions of the letters to show how the <\/strong>Journal <\/em><\/strong>had edited them.<\/strong> They called the MODs on systematically merchandising doubt.<\/p>\n\n\n\n

      The MOD’s Response<\/h3>\n\n\n\n

      In July, Seitz, Singer, and ozone-hole-denier Hugh Ellsaesser responded in the <\/strong>Journal <\/em><\/strong>and denied the charges.<\/strong> Singer accused the IPCC of coming to a \u201cfeeble\u201d conclusion but also claimed that it was scare-mongering.<\/p>\n\n\n\n

      Bolin and Santer responded, and Singer tried to attack them again, but the Journal <\/em>wouldn\u2019t publish him. Singer circulated an email instead with wild claims:<\/strong> There was no evidence for warming, the chapter had been based on \u201cunpublished work,\u201d and Patrick J. Michaels should have been a lead author because he was the only person to publish on climate fingerprinting before 1995. (All of this was verifiably untrue<\/strong>\u2014for example, the first paper on fingerprinting was published in 1979, and Santer circulated his own email to explain.)<\/p>\n\n\n\n

      In November, Singer kept making claims that were easily fact-checkable<\/strong>\u2014for example, he claimed that the discussion of uncertainty in Chapter 8 had been cut, but the report had been out for months and anyone who looked at it could tell it included six pages about uncertainties. However, the mass media publicized his and other MOD’s views and voices.<\/strong> (A 2004 study that looked at media from 1988-2002 discovered that over 50% of articles were balanced and 35% did acknowledge that one position was correct but still included the deniers’ views.)<\/p>\n\n\n\n

      Policy and Public Action<\/h3>\n\n\n\n

      Even though the MOD’s claims were false, their work influenced Bush, members of Congress, and millions of members of the public<\/strong> who read the Wall Street Journal<\/em>.  The U.S. withdrew from the Kyoto Protocol, which committed countries to reducing greenhouse gases, in 1997.<\/p>\n\n\n\n

      Further Exploration of the Science<\/h2>\n\n\n\n

      In 2001, the IPCC\u2019s latest assessment found more and stronger evidence of anthropogenic global warming. In 2007, the assessment named it \u201cunequivocal.\u201d<\/p>\n\n\n\n

      Policy and Public Action<\/h3>\n\n\n\n

      Despite the strength of the science, the \u201cdebate\u201d persisted.<\/strong> In 2006, only 56% of Americans thought that the average global temperature had increased. 85% thought it was happening but 64% thought there was still a lot of conflict between scientists. In 2009, the number of people who believed there was evidence for global warming actually declined <\/em>from 71% to 57%.<\/p>\n\n\n\n
