First of all, I will point out that he brings up the “context” of facts as a vehicle for an agenda early in the book. The book can essentially be described as a critical reading and overview of the IPCC reports.
And, yes, I do not agree with every point he makes. I think some of the things he says are misleading. That said, he does raise points that climate action advocates, myself included, need to address. For instance, our faulty climate models. This is not climate denial. It’s climate action, from a realistic perspective.
