A new research reported in Nature reveals what 2C warming – a increase over pre-industrial global average geothermal gradient at this point – might actually look like or what areas will be struck toughest.
Two of the mentioned national hot spots are also the Mediterranean nations, Brazil as well as the United States, where 2C of climate change may turn into surface temperature changes with more than 3c. But the area where most is likely to endure is the North sea, where overnight readings are projected to rise by 6C.
