What he is doing is good. He is using his platform (i.e. the fact that people know his name, journalists want to write about him, and people want to read articles about him) to promote policies that are created by experts.

If you want to read these ideas straight from the experts, then go read the IPCC climate report, but most people aren't going to go read that on their own.
