Back when Concorde was first built the doomsayers forecast that the exhaust gases left in the stratosphere would cause cloud blankets and global cooling. The end of the world was nigh.
But then academics love getting their name published. It sort of gives them street cred amongst their fellow egg heads. Also helps land that government grant to keep them employed for a few more years.The fact that its bullsh*t matters not. Just get your name in the media attached to your latest theory.
Well Concorde came and went and we are still here. Funny about that.
Now we are told its global warming to worry about. Warming, cooling I can't
sleep at night worrying.
