Open Letter to the United States Congress
The Truth About Climate Change Open Letter: On 28 January 2011, eighteen scientists sent a letter to members of the U.S. House of Representatives and the U.S. Senate urging them to "take a fresh look at climate change." Their intent, apparently, was to disparage the views of scientists who disagree with their contention that continued business-as-usual increases in carbon dioxide emissions produced from the burning of coal, gas, and oil will lead to a host of cataclysmic climate-related problems.
