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.

When the great ice sheets start going down: the age of storms

Robert Scribbler / 04 June 2015

ice-mass-loss-all-glaciersThe great ice sheets are melting with increasing velocity. Melt ponds are forming over Greenland, then pounding heat down through the ice like the smoldering hammers of ancient Norse fire giants. Warming mid-depth ocean waters are eating away at the undersides of Antarctica’s great ice shelves. Pools of fresh water are expanding outward from the bleeding glaciers, flooding the surface zones of the world’s oceans. Sea level rise rates have jumped to 4.4 millimeters per year (see study here). And the North Atlantic Overturning Circulation (AMOC) is slowing down.

Keeping all this in mind, let’s talk a little bit about the ugly transition to phase 2 climate change. A transition it now appears we’re at the start of. The — you should have listened to Dr. James Hansen and read The Storms of My Grandchildren — phase of climate change. The awful, long, stormy period in which the great glaciers really start going down.

In an effort to organize how human-caused climate change may proceed, it helps to break the likely progression of human-caused climate change down into three basic phases. For this simplification we have phase 1 — polar amplification, phase 2 glacial melt and storms, and phase 3 — runaway hothouse and stratified/Canfield Oceans. For this article, we’ll focus mostly on phase 1 and 2.

What is really going on? What are the big stories the media leaves out, while they fill the news with quirky headlines and fluff? All over the world, from pole to pole, the Earth and her species are going through big changes. The atmosphere is trapping heat into the oceans, air, and land.

This week I’m going to cover five of those big stories, with the help of one of the world’s best risk watchers. He’s author Robert Marston Fanney, and his launching pad is called Robert Scribbler’s Blog.

The Transition Framework

Resilience is the ability of a system or community to withstand impacts from outside. An indicator is a good way of measuring that. Conventionally, the principal way of measuring a reducing carbon footprint is CO2 emissions. However, we firmly believe that cutting carbon while failing to build resilience is an insufficient response when you’re trying to address multiple shocks such as peak oil, climate change and the economic crisis together.
