"...warming generally meant the mercury rose in the thermometer..."

Come to MY yard in Maryland USA. We have all YOUR lost degrees and more.... and the polar bears have some of them also. Inuits are having trouble finding safe places to fish & hunt as sea ice melts early.
Glaciers are melting in Alaska and Antarctica... it was 111F (43.89C) in Kansas a couple days ago. Don't worry, you'll get your share.
