Here's an article to consider:
I am actually old enough to remember the panic about the coming Ice Age and wondering as a child where in the world could we live, since I hated the cold and "didn't want to die". Do some research, and check out what many scientists are saying.

It only means they are passionate, for the moment, about what they are talking about.
Thanks for reading this.
