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.

Arctic sea ice extent breaks record low for winter

The Guardian / Suzanne Goldenberg / 28 March 2016

Arctic sea iceA record expanse of Arctic sea never froze over this winter and remained open water as a season of freakishly high temperatures produced deep – and likely irreversible – changes on the far north.

Scientists at the National Snow and Ice Data Centre said on Monday that the sea ice cover attained an average maximum extent of 14.52m sq km (5.607m sq miles) on 24 March, the lowest winter maximum since records began in 1979.

The low beats a record set only last year of 14.54m sq km (5.612m sq miles), reached on 25 February 2015.

“I’ve never seen such a warm, crazy winter in the Arctic,” said NSIDC director Mark Serreze. “The heat was relentless.”

It was the third straight month of record lows in the sea ice cover, after extreme temperatures in January and February stunned scientists.

No winter for the Arctic in 2016

Robert Scribbler / 18 February 2016

nasa-temperature-anomaly-map-january-2016Anyone who observes the Arctic — from scientists, to environmentalists, to emerging threats specialists, to weather and climate enthusiasts, to just regular people unsettled by the rapidly unraveling state of our global climate system — should be very, very concerned. The human greenhouse gas emission — now pushing CO2 levels to above 405 parts per million and adding in a host of additional heat trapping gasses — appears to be rapidly forcing our world to warm. To warm most swiftly in one of the absolute worst places imaginable — the Arctic.

Not only was January of 2016 the hottest such month ever recorded in the 136 year NASA global climate record. Not only did January show the highest temperature departure from average for a single month — at +1.13 C above NASA’s 20th Century base-line and about +1.38 C above 1880s averages (just 0.12 C shy of the dangerous 1.5 C mark). But what we observed in the global distribution of those record hot temperatures was both odd and disturbing.

The impending ecosystem collapse

Counterpunch / Robert Hunziker / 14 July 2015

Signals of planetary stress are literally off the charts, meanwhile the world continues spinning like always, as people go to work, drive cars, go out to dinner, and watch TV, some read books but not much these days.

Those routines of going to work, out to dinner, and so forth maintain an equilibrium, a daily pattern on the same freeways, the same faces, the same workplaces. By itself, life seems very normal, nothing much to worry about other than making monthly car payments.

Similarly, the natural world experiences its own rhythm, like the everyday cycle of people going to work, on the freeway, to dinner, watching TV. But, radically dissimilar to that everyday cycle that seems so dependable, so routine, the natural world is amiss, chaotic, crumbling apart, bursting at the seams. However, this deep trouble is not noticed, not recognized, not reported in accordance with severe levels of impending calamity. After all, as long as Wall Street goes up, all is well, isn’t it? Yet, all is not well, not by a long shot.

The Transition Framework

What the Transition movement does incredibly well is small-scale experiments which are practical, which resonate with local people, which look as if they’re doable, and that can engage people at a practical and meaningful level. It connects up the big issues and the local issues and shows you that change can happen at a local level.
