Challenges to policy proposals for how to deal with this problem should be welcome — indeed, a good-faith debate is essential for wise public policymaking.

But the attacks against the science must stop. They are not good-faith questioning of scientific research. They are anti-science.

How can I assure young researchers in climate science that if they make a breakthrough in our understanding about how human activity is altering our climate that they, too, will not be dragged through a show trial at a congressional hearing?…

My fellow scientists and I must be ready to stand up to blatant abuse from politicians who seek to mislead and distract the public. They are hurting American science. And their failure to accept the reality of climate change will hurt our children and grandchildren, too.
