the end of the world has been coming since the beginning of story telling around the campfire, in the 70's we were told by environmentalist that, due to overpopulation we would run out of resources by the nineties with certain mass death/destruction by 2000- some of this would be due to the ice age, the anthropogenic global warming religion hadn't yet been invented.
In the 80's it was "save a tree" so the environmentalist made every store switch to plastic bags- at the time I tried telling them that at least paper was bio degradable but the doomsday environmentalist always know more than everyone else.
The climate change/globalwarming religion is no different then any Christian apocalyptic sect psychologically. they just have different irrational beliefs
I may not be here now but I was there then
