This is not the 17th century, when "beliefs" trumped science, forcing Galileo to recant his understanding of the solar system. The president should unequivocally support the climate science community, which is under politically orchestrated assault on the legitimacy of its scientific assessments. If he needs reassurance or cover, the president can ask for a prompt report from the National Academy of Sciences, established by Abraham Lincoln for advice on technical issues.
Why face the difficult truth presented by the climate science? Why not use the president's tack: just talk about the need for clean energy and energy independence? Because that approach leads to wrong policies, ineffectual legislation larded with giveaways to special interests, such as the Waxman-Markey bill in the House and the bills being considered now in the Senate.
