True, and a lot of “scientists” use data as a con man would, and this fraud Michael Mann is on of them.
Was he the author of the e-mail that said “We’ve got to get rid of the Medieval Warm Period”? If not, I’m sure he agreed with the sentiment.
If he were to tell me “we don’t need data, we can see climate change” I would reply “Damn right. If the climate keeps getting warmer, pretty soon Vikings will be able to raise cattle in Greenland. Just like they did a thousand years ago.”
