This extreme cold is just weather but all heat waves are climate change

Don’t take it from me, take it from the former President of American Meteorological Society (AMS) and a current Director of the University of Georgia’s (UGA) Atmospheric Sciences Program. Marshall Sheppard would know, he has written over “80 peer reviewed papers” which gives him secret weather knowledge. It’s a kind of smarts that people who analyze MRI scans, design aerofoils or find minerals 3,000m underground can only aspire to.

He’s worried that people are mocking climate change, just because snap-frozen sharks are washing up on the beach, and it’s hitting minus 50C in Canada. In the last twenty years mankind has put out more than a third of all the CO2 homo sapiens has ever made since Homo Erectus lit their last fire.
