Heat records broken in the Canadian Arctic
Inuvik, NWT (68.3°N) exceeded 30°C three days in a row for the first time on record.
Another week, another parade of simultaneous heatwaves around the Northern Hemisphere, and the normally chilly Arctic is not immune. Much-above-normal temperatures are roasting eastern Scandinavia/western Siberia, far northeastern Asia, and northwestern North America. The Arctic is warming at least 3 times faster than the globe as a whole, fueling tundra fires, speeding the melt of land ice and sea-level rise, and accelerating the thaw of once permanently frozen Arctic soils. Rising concentrations of heat-trapping greenhouse gases, due mainly to burning fossil fuels, is the underlying disease causing these symptoms. We have the tools and power to slow this change, but what we lack is time. Actions must be swift and substantial to avert a worsening epidemic of extreme weather events.
