Revved-up climate change now permeates Americans' daily lives with harm that is 'already far-reaching and worsening across every region of the United States,' a massive new government report says.
Since 1970, the Lower 48 states have warmed by 2.5 degrees (1.4 degrees Celsius) and Alaska has heated up by 4.2 degrees (2.3 degrees Celsius), compared to the global average of 1.7 degrees (0.9 degrees Celsius), the report said. But what people really feel is not the averages, but when weather is extreme.
Compared to earlier national assessments, this year's uses far stronger language and 'unequivocally' blames the burning of coal, oil and gas for climate change.
