Update on the Antarctica Meltdown:

I got a heads-up from Robertscribbler. He's snagged some research on the meltdown now going on in the Antarctic:

Unfortunately, Totten is just one of many large glacial systems that are now destabilizing across Antarctica. And researchers are now beginning to identify significant potential sea level rise contributions from Antarctica alone (ranging from two feet to nearly two meters) before the end of this Century. In New Scientist, during March, Antarctic researcher Rob Deconto notes:

“Today we’re measuring global sea level rise in millimetres per year,” DeConto says. “We’re talking about the potential for centimetres per year just from [ice loss in] Antarctica.”

Centimeters per year sea level rise is about ten times faster than current rates and implies 100 year increases — once it gets going — in the range of 2 to 3 meters. Such increased melt does not include Greenland’s own potential sea level rise contribution. Nor does it include sea level rise from other glacial melt and ocean thermal expansion. As such, it appears that multi-meter sea level rise is becoming a more and more distinct possibility this Century. Furthermore, the paleoclimate context is now pointing toward catastrophic levels of overall melt and sea level rise if global greenhouse gasses aren’t somehow stabilized and then swiftly reduced.

And don't forget Sea-Level Changes -- with a lot of rises away from Greenland and especially Antarctica -- from the redistribution of waters released from the Ice caps' gravity.

A meter here, a meter there and pretty soon you’re in for some wicked serious sea-level rise!

From Discover: "The Arctic will 'go through hell this year,' says one prominent scientist."

On April 11, a dramatic early spike in melting of snow and ice at the surface of Greenland’s ice sheet prompted a Danish climate scientist to say that she and her colleagues were “incredulous.”
Now, there has been a second bout of unusual melting.

You can see both of them in the graph above from the National Snow and Ice Data Center, or NSIDC. It charts the percentage of the Greenland Ice Sheet experiencing surface melting. In both cases, the thaw exceeded 10 percent of the ice sheet’s area.

Also record warmth (except in Berlin, NY and other areas in northeast North America and in Europe) gripped the globe last month.

The above graphic shows April temps to be 1.11 degrees C (2.0 F) above the 1951-1980 mean, or about 1.33 C (2.4 F) above 1880s values.

From the BBC: "April was the seventh month in a row that broke global temperature records, Nasa figures show."

Last month smashed the previous record for April by the largest margin ever, the data show.

That makes it three months in a row that the monthly record was broken by the largest margin ever.

But in terms of its departure from the 1951-1980 temperature average used by Nasa, April was equal with January 2016.

The Beeb also admits in the above linked article that with the new record temperatures, it will be quite difficult to meet the 1.5 C (2.7 F) goad set by COP21 in Paris last year.

All in all, the first four months of this year are running at 1.43 C (2.6F) above 1880s levels.

And the Fossil Fuels Derivatives Beast will be doing quite a number on global industrial civilization, putting 13 billion people and $US 158 trillion in infrastructure, buildings, farms, etc.

The global community is badly prepared for a rapid increase in climate change-related natural disasters that by 2050 will put 1.3 billion people at risk, according to the World Bank.

Urging better planning of cities before it was too late, a report published on Monday from a Bank-run body that focuses on disaster mitigation, said assets worth $158tn – double the total annual output of the global economy – would be in jeopardy by 2050 without preventative action.

“With climate change and rising numbers of people in urban areas rapidly driving up future risks, there’s a real danger the world is woefully unprepared for what lies ahead,” said John Roome, the World Bank Group’s senior director for climate change.

“Unless we change our approach to future planning for cities and coastal areas that takes into account potential disasters, we run the real risk of locking in decisions that will lead to drastic increases in future losses.”

According to the Guardian in this same article, The World Bank Report reveals that the coastal cities are also sinking, compounding the sea-level rise... which will not be uniform across the globe. One country on one continent in particular is really gonna get in trouble...

Arctic Ice Suffers Severe Melt-back as Satellite Monitor Begins to Fail.

This is a reblogging of and commenting on two recent articles posted by Robert Scribbler. Please note that this is not the only pole that's suffering ice melt. Antarctica is now melting, too.

First, Robert Scribbler predicts that the Arctic Ice will just about completely disappear by the end of this summer, and he backs it up with EVIDENCE, such as the now-ongoing break-up and meltback of ice in the Beaufort Sea:

Arctic Sea Ice is Falling off a Cliff and it May Not Survive The Summer

By Robert Scribbler 2 May 2016

Near zero sea ice by the end of melt season. The dreaded Blue Ocean Event. Something that appears more and more likely to happen during 2016 with each passing day.

These are the kinds of climate-wrecking phase changes in the Arctic people have been worrying about since sea ice extent, area, and volume achieved gut-wrenching plunges during 2007 and 2012. Plunges that were far faster than sea ice melt rates predicted by model runs and by the then scientific consensus on how the Arctic Ocean ice would respond to human-forced warming this Century. For back during the first decade of the 21st Century the mainstream scientific view was that Arctic sea ice would be about in the range that it is today by around 2070 or 2080. And that we wouldn’t be contemplating the possibility of zero or near zero sea ice until the end of this Century.

Melting more than Two Weeks Faster than the Early 2000s

Since April 27th, according to a record of sea ice extent provided by JAXA, daily rates of sea ice loss have been in the range of 75,000 square kilometers for every 24 hour period. That’s 300,000 square kilometers of sea ice, or an area the size of New Mexico, lost in just four days. Only during 2015 have we ever seen such similarly rapid rates of loss for this time of year.

We’ve never seen early season sea ice losses like this before. Severe sea ice losses of this variety can help to generate strong ridges and extreme heatwaves [and wildfires] like the ones we now see affecting [Canada,] India and Southeast Asia.

According to the rates of decline shown for this year, last year, 2007 and 2012, we are in for a record low area of Sea Ice Extent up in the Arctic. And one of the areas is the Beaufort Sea, described by Robert Scribbler, wherein there is a huge area of exposure of water close to the sea coast and the Canadian Archipelago, and an immense area of sea ice that is in shards:

This Beaufort sea has never looked so bad off so early in the year. High amplitude waves in the Jet Stream continue to deliver record warmth, warm, wet winds, and record sea ice melt to this region of the Arctic. For reference, bottom of frame in this image is around 600 miles. The wispy threads you see in the image is cloud cover, the sections of solid white are snow and ice. And the blue you see is the open waters of the Arctic Ocean. Open water gap size in the widest sections is now more than 150 miles.

There, ice continues to rapidly recede away from the Arctic Ocean shores of the Mackenzie Delta and the Canadian Archipelago — where a large gap has opened up in the sea ice.

All this melting ice on sea and land will eventually convert to rising seas, and will inundate areas like Southern Louisiana, South Florida, the Chesapeake Bay including such major cities like New Orleans, Miami and Washington, D. C.

We can head it off if we do a crash program to get away from fossil fuels cold-turkey and start extracting carbon out of the atmosphere. But I have my doubts that this is politically possible at all.

And the US Congress and Senate are not helping. The GOP wants to cut everywhere except the War Department, and the Democrats are so ineffectual at stopping them, they are enablers. Which is why the Arctic Ice Satellite Monitor is starting to go on the fritz:

Republican Climate Change Denial is Blinding Our Ability to Observe the Arctic

By Robert Scribbler 26 April 2016

Denial.

It’s all-too-often what happens to the powerful when they are confronted with the consequences of their own bad actions. It can best be said that denial is blindness — the willful inability to open one’s eyes to the tough reality of the world. In literature, we can see denial in the tragic sin of hubris and in the metaphor of Oedipus the King gouging his own eyes out as a result of his failure to come to terms with the warnings of prophecy.

In the psychological sense, denial involves the inability to cope with reality such that a person will act in an irrational fashion to the point of generating fantasies that the object of said denial does not exist. Behaviorally, this results in an increasing degradation of a person’s ability to confront or cope with the object of denial — to the point of ardent, irrational, and possibly destructive outbursts when faced with it.

Arctic sea ice loss.

Ever since 1979 an array of satellite sensors has allowed our scientists to directly observe the sea ice in the Arctic. Since that time, and as a human-forced warming of the world ramped up, the area which that ice covers has dramatically shrunken. So much so that by this year, 2016, there’s a risk that not only will a new all-time record low be reached, but that by the end of this summer almost all the ice in the Arctic Ocean will be melted out entirely. A risk that a new climate change related event will start to take shape in the Arctic. The blue ocean events.

Comment in red mine.

Arctic sea ice area as measured by observational satellites and most recently by  F17. The bottom line of the graph measures days of the year. The left side of the graph measures sea ice area. The corresponding intersections determine sea ice area on any given day of a year in the record. The up and downward swoop of each line on the graph shows the seasonal variation of sea ice area for that given year. The blue line on the graph represents 1980 sea ice area. The dark gray line represents the 1979 to 2000 average. The red line represents the 2012 record low year. 2016, in black, shows a squiggle as F17 begins to fail in early March of this year — a year that could significantly beat 2012 as the worst melt year on record. The sensor is failing because it is old and needs replacement. A replacement that is now sitting in a warehouse due to republican-led satellite research funding cuts.

Willful Blindness

Where does denial meet with Arctic sea ice loss? In the form of climate change denying republicans attempting again and again to cut and with-hold funding to NASA and NSIDC instruments that track what is an unprecedented and historic melt now ongoing. For ever since their coming to power in Congress in 2010, republicans have done everything they can to remove funding for the devices that provide a direct observation of the changes coming as a result of a human-forced warming of our world.
