The authors wrote a joint letter to the editor in response objecting to the impression given by the article that their "research goes against the consensus scientific view that global warming is a serious concern." They went on to state their work did not argue against the seriousness of the problem and that the potential effects were so serious "that slight overestimates of this warming make little difference -- just as reducing the size of a firing squad from 10 shooters to nine makes little difference to the person being executed."

Books

Dessler and Edward Parson co-authored, '' The Science and Politics of Global Climate Change: A Guide to the Debate'' in 2006 (2nd ed. 2009). It was described as, "a fascinating hybrid of science and policy directed at a broad or nonspecialist audience" by Wendy Gordon in a 2008 review in ''

Climate change policy

Dessler has been consulted by newspapers and has given talks on climate change and government policy. On January 16, 2014 he testified before the US Senate Committee on Environment and Public Works. He stated that with almost 200 years of study by the scientific community of the climate system a robust understanding has emerged. He continued stating, the climate is warming and "humans are now in the driver's seat". He concluded, "We know that, over the next century, if nothing is done to rein in emissions, temperatures will likely increase enough to profoundly change the planet." He gave a talk at the
