Why don't you ask the experts? Try IPCC - Intergovernmental Panel on Climate Change. I'm an engineer with the Navy.
I'm a brain surgeon....the IPCC wants the redistribution of wealth on a global level. Yeah, no partisanship on their behalf. And, you don't have to be a brain surgeon to figure out their shtick.
