“Climate change is real and in part, man made”
Rick Perry
oops!
Of course climate change is real. A hundred thousand years ago Lake Michigan didn’t exist and would have been under a mile of ice if it did. The climate changes all the time. A volcano can cause the temperature of the world to drop several degrees as it did in “the year with no Summer.”
And man probably does have some impact but we don’t know whether it causes the temperature to go up or down.
