It's also somewhat misguided in my opinion. For some reason a large portion of the population have decided that it is categorically impossible to do anything about global warming from a technical or policy perspective. They have thrown up their hands and have decreed that we must all live awful lifestyles and shouldn't even try to innovate our way out of the problem. We are spending a tiny fraction of available resources fighting this problem, and it is not inconceivable that we could develop solutions which would change the state of the world dramatically if we actually threw money and talent at the problems.
