<p>In November 2009, ASA Past-President Sally Morton joined with the leaders of 17 other science organizations to sign a <a href="http://www.amstat.org/outreach/pdfs/climateletterfinal.pdf"><font color="#3c78a7">letter</font></a> (pdf) to all U.S. senators summarizing the consensus of climate change science. In short, the letter cited the strong scientific evidence that climate change is happening and that human activities are the primary driver. It went on to list the many likely consequences, some of which are already starting to occur.</p>
<p>As members of the ASA’s <a href="http://www.amstat.org/committees/ccpac/"><font color="#3c78a7">Climate Change Policy Advisory Committee</font></a>, we commented on early drafts of the letter and, upon reviewing the final version, advised Morton to sign it. We are well aware that some disagree with the statements in the letter. The views of climate change ’skeptics’ and ‘deniers’ appear in many media, from blogs and videos to op-eds and congressional testimony. We prefer to think of the views of skeptics as part of the scientific spectrum, but nevertheless believe they are a minority who do not represent the mainstream scientific viewpoint.</p>
<p>Some organizations that feature these views in sophisticated advertising campaigns have manipulated the evidence to create the impression that the consensus among climate scientists is quite different from what it is. Here, we comment on some of the most common arguments that climate change is not happening or that humans are not responsible.</p>
