Brothers Charles and David Koch run Koch Industries, the second-largest privately owned company in the U.S., behind Cargill. They've given close to US$70 million to climate change denial front groups, some of which they helped start, including Americans for Prosperity, founded by David Koch and a major force behind the Tea Party movement.
Again, of course anyone with any sense and an awareness of climatological realities believes the whole global energy production and usage system needs to change, to be reengineered in a huge hurry. But those who control the resources to get started on this -- e.g., the the loathsome Cock Brothers refuse to acknowledge the necessity of change. They are spending a fortune to persuade people that harm is not hurriedly heading our way, and there seems to be no way to stop their suicidally stupid buy the reality they wish to believe in.
I don't know what it will take, what horrific environmental collapse will get them to see that they are drilling ever more holes in the deck of a sinking boat.
