It's good that people with extreme views like Pierrehumbert are part of the process. It's better than trying to lock them out. Make them engage with others who have more nuanced positions---you can do that in the context of studies and panels, not so much when he's writing an op-ed and gets to

I don't understand how some authors claim that forests remove carbon from the atmosphere and so if you use the same land to produce and burn biofuels then that zero-carbon cycle is somehow worse for the environment than the natural cycle. Isn't it obvious that in the long run a forest has to be
