We have no reason to think that climate change is harmful if you look at the world as a whole. Most places in fact are better off being warmer than being colder. And historically the really bad times for the environment and for people have been the cold periods rather than the warm periods.
When I'm not writing I read loads of fiction but I've been writing quite constantly lately so I've been reading a lot of nonfiction - philosophy religion science history social or cultural studies.
