At least he can admit he’s being selfish I guess. I think most climate deniers, especially the older ones, simply can’t face the idea they might be responsible for terrible things happening, and don’t want to change now, so the brain latches on to any explanation that spares them that psychological pain. Thus arguing facts is pointless with these people because it’s about feelings not actual truth (as many things are with our species). The solution is to hack peoples psyche to make them “feel good” about climate change, somehow…
