I'm reacting to a certain perspective that seems to be dominant when it comes to climate change discourse, wherein its common to take the most severe/pessimistic interpretation of the science and then categorize any less severe interpretations as insufficient. I think that's a poor approach and only serves to alienate people who may be looking for something a little more even-handed or closely aligned with the trends in the science (as opposed to clinging to the extremes).
Having said that, I think that even the most optimistic interpretations of climate change are compelling enough to warrant immediate and dramatic action. But we should all strive for the most accurate interpretations of the science, which means being flexible and not dogmatic.
I don't know anything about biological factors of iq, but I'll take that kind of denialism, ie: all people are capable irrespective of their skin color, gender, other biological traits, over the former which will do lasting harm to persons all over the world and destroy massive amounts of wealth and productivity.
