I am scared. I have two friends, both with "hard" science doctorates, who deny both climate change and warming. They are both Libertarians who also believe that doing nothing is sufficient because "This is just a natural cycle and will self correct itself." Of course, they believe they and/or their descendants will be around after the correction takes place.

Saw this on one of my newsletters today:

Of course, one of my friends' points is that anything we do will have minimal or nil effects.
