Cause for ‘The Pause’ #38 – Cause of global warming hiatus found deep in the Atlantic Ocean

From the University of Washington  and the department of Trenberth’s missing heat comes a claim that we’ll have to wait another 15 years for global warming to resume. Sounds like a goalpost mover to me. The Oceans that Slowed 21st … Continue reading
