A thaw of Arctic ice and snow is linked to worsening summer heatwaves and downpours thousands of miles south in Europe, the United States and other areas, underlying the scale of the threat posed by global warming, scientists said.

Extreme weather events, particularly droughts and elevated bushfire conditions, are becoming more likely across south-eastern Australia because of climate change, said Wenju Cai, a research scientist with CSIRO.
Cathryn Wellner's insight:
As if Australia were not already fire and drought prone...
Limiting global warming to the international goal of 2 degrees may trigger some important tipping points in the climate and much more extreme conditions will result if temperatures continue on their present trajectory, a US scientist has said.
