I also don't think that climate change is going to be a problem in any way comparable to a nuclear world war. Don't get me wrong, changing climates and warming will have negative consequences to a lot of people. But global nuclear winter is inconceivably worse in every way. Climate change stuff is mostly alarmist shouting in a highly politicised environment, almost more of an ideology than an actual environmental catastrophy of extinction level proportions.
