James Connaughton, Chairman of the White House Council on Environmental Quality, wrote a letter to the editor to clarify statements made about the U.S. Climate Action Report 2002. The letter notes that while the report presents uncertainties, it is consistent with previous statements by President Bush acknowledging rising temperatures and greenhouse gases primarily due to human activity. It also restates that the administration's policies prudently address climate change given the current limits of scientific knowledge, through programs reducing emissions and billions invested in research each year.
