Mikey Mann Plays An April Fool’s Prank On Cleveland

Cleveland could play a role in our nation’s thinking on environmental protection again. That’s the hope of a leading climate scientist who spoke at the Cleveland City Club today.

Penn State Professor Michael Mann and his partners published in 1999 a now famous graph of global temperatures over the last one thousand years. The so-called hockey stick graph was a stark illustration that the earth was suddenly getting warmer.

He says that’s proved to a bad thing. “Not unless you think unprecedented super-storms and floods and droughts and heat-waves are a good thing. If you think that’s a good thing then I suppose climate change is a good thing.”
