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.

Update: Arctic sea ice minimum volumes 1979-2015

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.

‘Bombshell’ study: World’s oceans could rise higher, sooner, faster

Common Dreams / Jon Queally / 21 July 2015

nyc-under-waterAccording to the new study—which has not yet been peer-reviewed, but was written by former NASA scientist James Hansen and 16 other prominent climate researchers—current predictions about the catastrophic impacts of global warming, the melting of vast ice sheets, and sea level rise do not take into account the feedback loop implications of what will occur if large sections of Greenland and the Antarctic are consumed by the world’s oceans.

A summarized draft of the full report was released to journalists on Monday, with the shocking warning that such glacial melting will “likely” occur this century and could cause as much as a ten foot sea-level rise in as little as fifty years. Such a prediction is much more severe than current estimates contained in reports issued by the Intergovernmental Panel on Climate Change (IPCC)—the UN-sponsored body that represents the official global consensus of the scientific community.

The Transition Framework

Transition initiatives share many of the same goals as other groups, and works collaboratively with a variety of organizations in their local areas. Transition differs in that it focuses specifically on preparing communities for the changes associated with unprecedented resource depletion and transitioning away from fossil-fuel dependency.
