To our dismay, and the nation’s detriment, self-described climate change deniers – strongly supported by fossil-fuel interests — continue to mislead Congress and the public. In late January, we joined 14 other leading scientists in writing a letter to every member of Congress, asking our elected representatives to separate science from policy. We called attention to the overwhelming scientific evidence of climate change, urging Congress to “address the challenge of climate change, and lead the national response…” We want Congress to understand that, with each passing day, the problem worsens.
