The southern hemisphere just went through an all time cold and nasty winter. Hundreds died from the extreme cold conditions. The northern sea ice (Northwest Passage) froze up at an unprecedented rate this year. Minneapolis temperatures last month were 11 degrees colder than last year. All caused by global warming. Yeah. Sure.
