The first I ever heard about global warming was 1968 when it was mentioned by my school teacher at the time. A billion things have been mentioned since and I have listened to both sides of the argument and whether it is caused by A, B or C.
But today I read something that is the most profound of all the arguments:
The overwhelming consensus among climate scientists is that human-caused climate change is happening. Yet a fringe minority of our populace clings to an irrational rejection of well-established science. This virulent strain of anti-science infects the halls of Congress, the pages of leading newspapers and what we see on TV, leading to the appearance of a debate where none should exist.
Bingo. Got it in one.
The rest of the article isn’t bad either. ;-)
