Heatwave in Arctic - Pangnirtung hotter that Toronto

Pangnirtung, Nunavut recorded temperatures of 10 C (in the shade) yesterday, according to Environment Canada. The community is located almost 300 kilometres northeast of Iqaluit on Baffin Island, just south of the Arctic Circle.

Seasonal temperatures are usually closer to —7 C. Temperatures in Pangnirtung matched those in Ottawa Tuesday, but soared past downtown Toronto, where temperatures only reached 5 C by mid-afternoon. Pangnirtung residents say warmer and earlier springs are becoming the new normal. "It's like June right now," said Adamie Komoartok.
The temperature in Nuuk, the capital of Greenland is 13 C. As has been detailed here, the Greenland Ice sheet has already started its seasonal melt, some 6 weeks earlier than normal. Typical average for April 27 varies from -2°C to -1°C.

The earth has over eons stored greenhouse gasses in forests, the soil and in the oceans. Small rises in temperature can trigger these sinks into becoming sources, and thus tip the scales. Evidence is pointing with growing clarity that global warming is reaching it's 'tipping points'. This is an irreversible moment when the dreaded feedback loop begins.

There is a growing sense of dread ... have humans already have gone too far, and are we helpless to stop abrupt and runaway global warming?
