Scientists marvel at ‘increasingly non-natural’ Arctic warmth

Washington Post / Jason Samenow / 02 February 2017

The Arctic is so warm and has been this warm for so long that scientists are struggling to explain it and are in disbelief. The climate of the Arctic is known to oscillate wildly, but scientists say this warmth is so extreme that humans surely have their hands in it and may well be changing how it operates.

Temperatures are far warmer than ever observed in modern records, and sea ice extent keeps setting record lows.

2016 was the warmest year on record in the Arctic, and 2017 has picked up right where it left off. “Arctic extreme (relative) warmth continues,” Ryan Maue, a meteorologist with WeatherBell Analytics, tweeted on Wednesday, referring to January’s temperatures.

Veteran Arctic climate scientists are stunned.

Arctic ice melt could trigger uncontrollable climate change

The Guardian / Fiona Harvey / 25 November 2016

arctic-sea-ice-2016-11Arctic scientists have warned that the increasingly rapid melting of the ice cap risks triggering 19 “tipping points” in the region that could have catastrophic consequences around the globe.

The Arctic Resilience Report found that the effects of Arctic warming could be felt as far away as the Indian Ocean, in a stark warning that changes in the region could cause uncontrollable climate change at a global level.

Temperatures in the Arctic are currently about 20C above what would be expected for the time of year, which scientists describe as “off the charts”. Sea ice is at the lowest extent ever recorded for the time of year.

“The warning signals are getting louder,” said Marcus Carson of the Stockholm Environment Institute and one of the lead authors of the report. “[These developments] also make the potential for triggering [tipping points] and feedback loops much larger.”


North Pole is an insane 36 degrees warmer than normal

Washington Post / Chris Mooney, Jason Samenow / 17 November 2016

temperature-anomalies-2016-11It’s polar night there now — the sun isn’t rising in much of the Arctic. That’s when the Arctic is supposed to get super-cold, when the sea ice that covers the vast Arctic Ocean is supposed to grow and thicken.

But in fall of 2016 — which has been a zany year for the region, with multiple records set for low levels of monthly sea ice — something is totally off. The Arctic is super-hot, even as a vast area of cold polar air has been displaced over Siberia.

At the same time, one of the key indicators of the state of the Arctic — the extent of sea ice covering the polar ocean — is at a record low. The ice is freezing up again, as it always does this time of year after reaching its September low, but it isn’t doing so as rapidly as usual.


Arctic Sea ice minimum volumes 1979-2016

Andy Lee Robinson / 12 October 2016

The rate of ice loss in the Arctic is staggering. Since 1979, the volume of Summer Arctic sea ice has declined by more than 80% and accelerating faster than scientists believed it would, or even could melt.

The Transition Framework

The Transition Towns movement aims toward veering away from excessive consumption – to deal with the conjoined problems of peak oil and climate change – but also in the belief that we may create an essentially more contented society, through building strong and resilient local communities. We will get to know our neighbours better, because we shall all need one another in the time to come.
