The National Center for Science Education is now also engaging on teaching good science on climate change. I've long been a member, because they've been for even longer helping ensure that science is taught in biology classes. I'm not quick on the announcement, it was originally made on the 16th. But if you haven't seen the mention yet, it's new to you :-)
I'll add a few thoughts of my own as a long-time member, and one who had suggested some time back to the director, Eugenie C. Scott, that they take this step. One of the things I like about the NCSE is that their focus is on the science. They're not the place to go if, say, you want someone to lobby for your idea for solving climate change. They're a good place for parents, teachers, school boards, to go with questions and concerns about whether the science in your school's textbook is good, or is even science. NCSE is also a good place to go to find out what is happening in your state regarding attempts to change the science curriculum away from science. The main page address is http://ncse.com/
It was partly the tracking of attempts to remove teaching evolution in biology classes and other such anti-scientific moves that made me suggest also covering climate change science. Increasingly, over the last 10 years, bills opposed to teaching good science in biology classrooms have been including directives opposed to teaching good science in earth science classrooms. Bills to deny that CO2 is a greenhouse gas, or deny that there's a greenhouse effect, or to deny that CO2 is increasing and this is due to human activity, and other versions of denial.
