Northern and Uplands Permafrost Ready to Dramatically Increase Atmospheric Carbon.

Well it appears that peak oil really is no object -- climate change, a.k.a. global warming, and global weirding, is going to jump the gun what with the wildfires in the taiga and tundra and the immense store of Carbon locked in the permafrosts of the northern and upland regions (ex.: Alaska, Siberia, the Arctic, Tibet) is just about ready to offgas so much carbon into the atmosphere, the CO2 content in the atmosphere could actually triple (400 ppm to 1200 ppm). If that happens, we'll see a hothouse environment in nothing flat!

Hat tips to Colorado Bob, humortra and redskylite over at Robertscribbler.

Fires Rapidly Consume More Forests and Peat in the Arctic

http://www.scientificamerican.com/article/fires-rapidly-consume-more-forests-and-peat-in-the-arctic/

Third of a four-part series. For the first two parts, click here and here.

Scientists who study fire in the boreal are debating how global warming will affect the fire regimes here. Their work will have global implications. Boreal forests sprawl across circumpolar Canada, Russia, Alaska and Scandinavia, and comprise about 30 percent of global forests. They contain extensive, carbon-rich peatlands that have formed over the past 10,000 years.

The upper 20 feet of these water-logged, oxygen-poor soils contains carbon in the form of partially decayed vegetation. The boreal forests store an estimated 703 gigatons of carbon, almost all of it in the soils, according to a 2009 report.

As it warms, peatlands dry out, leaving them vulnerable to fire. And if fire becomes a larger part of the landscape, these vast stores of carbon could be released to the atmosphere, which could trigger more warming and thus create a feedback loop.

If the warming trend continues, the area burned annually could double by the end of the century, according to Natural Resources Canada, the federal ministry responsible for the management and study of the country’s natural resources, including its forests. Fires, more frequent droughts and insect outbreaks could make Canada’s boreal forests a source of carbon, the federal agency warns.

Permafrost in Tibetan Plateau can be wiped out by temperature rise


Much of the permafrost on the Tibetan plateau will possibly disappear by the end of the century under the present trend of global warming exceeding 2C. Almost 40% of it could be lost in the coming years, a Chinese report has warned, noting that the region has been seeing an average temperature rise of about 0.3C every decade.

The thawing has major implications for the local environment in terms of lake outbursts and landslides, besides contributing to global warming. More than half the plateau is covered in permafrost, with large reserves of carbon dioxide trapped within the frozen soil, the report from the Institute of Tibetan Plateau Research under the Chinese Academy of Sciences (CAS) said.

Permafrost: hiding a climate time bomb?

There is twice as much carbon in permafrost than in the atmosphere," said Florent Domine, a researcher with France's National Centre for Scientific Research (CNRS).

"So if we transformed all the carbon in the permafrost into CO2, we would triple the concentration of CO2 in the atmosphere, and that would mean the end of the world as we know it."

It contains an estimated 1.7 trillion tonnes of carbon in the form of frozen organic matter, which escapes as carbon dioxide (CO2) and methane as it warms and decomposes.

Study: Alaskan Boreal Forest Fires Release More Carbon than the Trees can Absorb

http://alaska-native-news.com/study-alaskan-boreal-forest-fires-release-more-carbon-than-the-ttrees-can-absorb-20315

CHAMPAIGN, Ill. — A new analysis of fire activity in Alaska’s Yukon Flats finds that so many forest fires are occurring there that the area has become a net exporter of carbon to the atmosphere. This is worrisome, the researchers say, because arctic and subarctic boreal forests like those of the Yukon Flats contain roughly one-third of the Earth’s terrestrial carbon stores.

 The research is reported in the journal Nature Climate Change.

I wouldn't wait for peak oil to correct this problem. The problem is, given the immensity of the scale of the required decarbonization of our living arrangements (especially in transportation in Australia and the USA), how do we accomplish this before it becomes completely unmanageable?
There is twice as much carbon in than in the atmosphere," said Florent Domine, a researcher with France's National Centre for Scientific Research (CNRS).
"So if we transformed all the carbon in the permafrost into CO2, we would triple the concentration of CO2 in the atmosphere, and that would mean the end of the world as we know it."
Permafrost is perennially frozen ground covering about a quarter of exposed land in the northern hemisphere.
It contains an estimated 1.7 trillion tonnes of carbon in the form of frozen organic matter, which escapes as (CO2) and methane as it warms and decomposes.

Several Items Today, September 23, 2015.

Global Warming was evident in the 1940s -- not just the tropics, but the Arctic, too. Rachel Carson, in the 1962 edition of her The Sea around Us, noted signs of climactic warming in Greenland in the 1940s including the arrival of warmer-climate plants and birds.

You can probably pick up a copy of it, new or used, at your local mom-and-pop bookstore. If that fails, there’s always Amazon.com and friends.

From dtlange at Robertscribbler:
– GIZMODO 0922

“the fact that most big research universities are located in countries with seasons— what’s happening in the tropics has been largely ignored.

We Could Have Discovered Climate Change As Early As the 1940s if We Had Just Looked

“Remarkably our research shows that you could already see clear signs of global warming in the tropics by the 1960s but in parts of Australia, South East Asia and Africa it was visible as early as the 1940s,” said lead study author Andrew King in a statement. (That’s decades before the the fore-thinking researchers at Exxon discovered global warming!)

Climate change is hitting high latitude ecosystems the hardest — the Arctic, for instance, is warming twice as fast as the world at large. For that reason — and the fact that most big research universities are located in countries with seasons— what’s happening in the tropics has been largely ignored.

But it will take another ten to thirty years for the signal-to-noise ratio to confirm it; i.e., the signal of global warming exceeds the  noise of natural variability.

Thirty years!? It’ll be too late to act then. Even ten years is cutting it.

With all the mass media brainwashing going on, who will wake all the masses before then? Is it even possible????

Researchers reveal when global warming first appeared

While temperature records generally showed pronounced indications of global warming, heavy rainfall events have yet to make their mark. The models showed a general increase in extreme rainfall but the global warming signal was not strong enough yet to rise above the expected natural variation.

“We expect the first heavy precipitation events with a clear global warming signal will appear during winters in Russia, Canada and northern Europe over the next 10-30 years,” said co-author Dr Ed Hawkins from the National Centre for Atmospheric Science at the University of Reading, UK.

“This is likely to bring pronounced precipitation events on top of the already existing trend towards increasingly wet winters in these regions.”
This is going to deprive Russia of more and more Natural Gas, and the revenues from exporting it...

From humortra at Robertscribbler:
A new expedition to one of the mysterious Siberian giant holes found in recent years has concluded that it is a warning sign of a deadly threat to northern regions as the climate warms.

Scientists from the respected Trofimuk Institute of Petroleum Geology and Geophysics insist the process by which a series of craters formed was caused by the melting of gas hydrates and the emission of methane.

This accumulates in a pingo – a mound of earth-covered ice – which then erupts causing the formation of the strange holes that have appeared on Russia’s Arctic fringe.

A pingo believed to be poised to explode ‘at any moment’ is now being constantly monitored by a Russian space satellite in an attempt to catch the moment when the eruption occurs.

Not so much apocalyptic as hearalding the coming global superstorms.

From Colorado Bob at Robertscribbler:
“It Felt Like the Apocalypse”: Israel Hit with Extreme and Unusual Weather on Jewish New Year
“It felt like the apocalypse, the rain has been torrential, there were about 10 lightning strikes in seconds, and even with your windshield wipers on high, it was impossible to see anything,” Mark Katz, a National Parks Authority employee, told the Times of Israel.

Since the beginning of September, Israel has experienced a series of extreme weather changes, beginning last week with a sudden sandstorm that blanketed the country in thick yellow dust.
The record setting five-day dust storm was also accompanied by a heat-wave, with new records reached across Israel in temperatures and air pollution.

Simple. Boil off all the water til there’s nothing left but salt. they [sic!]* you can market it as rock salt, or bury it.

From Maria at Robertscribbler:
Solar Desalination in California. The company will be desalinating irrigation drainage in the Central Valley. The article doesn’t talk about where all that brine will go….What is an appropriate method way to deal with desal brine?

snip

“Less than one percent of the world’s desalination is powered by renewable energy sources today, but that could all change soon if companies like California-based WaterFX have anything to say about it. Its Aqua4 “concentrated solar still” (CSS) uses a concentrated solar thermal collector to compress heat, create steam and distill water at 30 times the efficiency of natural evaporation. It can produce 65,000 gallons of freshwater per day—and it can desalinate a wide range of water sources, not just seawater.

"Solar desalination is a technique used to remove salt from water via a specially designed still that uses solar energy to boil seawater and capture the resulting steam, which is in turn cooled and condensed into pristine freshwater. Salt and other impurities are left behind in the still.

"To wit, the company will start employing solar desalination to treat some 1.6 billion gallons of salt-laden irrigation drainage from California’s drought-stricken, agriculturally-rich Central Valley next year. Crops extract nearly pure water from soil, leaving behind salt and other potentially toxic minerals like selenium that naturally occur in the water. These excess minerals must be drained from the soil, or crop productivity plunges. By treating this drainage, WaterFX can prevent about percent of farmland in California from being retired every year to make room for storage for untreated drainage water."

Maria on Robertscribbler also responded to the second item above. My response to her remarks follows them:
I saw your comment up thread re: we don’t have decades. I recently learned that the big People’s Climate March was partially subsidized by FF. we know that Paris talks are being partially funded by big oil & major emitters. I’m afraid that unless the grass roots-/-county-to-county and state to state citizens & their leadership take bold action? Decades, I’m afraid. Hope I’m wrong. And that a massive positive feedback loop re: renewals ensues, giving FF & nat’l leadership no choice but to follow.
Crap. Combined with corporate dominance of our “free” news media (including Russia’s) means any such attempts to get Peak FF’s before their natural peaking at least 15 years from now (too many in my opinion) will be met with derision and … get ready now … “ZOMG DOOMER PORN!!!!!!” spoken from every news media mouthpiece.

And the same media will say the American Way of Life (Suburban Utopia and Happy Motoring! TM) is still non-negotiable.

And people will fall for it, especially here in the United States, for we are the World’s easiest marks. And that is the reason why our country will do the right thing after trying everything else.

And there’s something like 8,000 GT of Carbon embedded in the permafrost and the sea beds, which are melting or getting ready to melt as we speak. Sam Caranas, not to mention the paleolithic-paleoclimactic record, has demonstrated that rapid uncontrolled releases of Carbon, especially in the form of Methane, are likely to lead to a hot house extinction right quick. But the ice will stick around for a thousand more years or so, which will put a brake on uncontrolled global overheating.

Sum it all up, and we face Near Term Human Extinction, maybe even NTE, (by 3015).

Some Items from around the Net Today.

Three developments that are bad, the first very, very bad -- i.e., a new, almost fully-automated gigantic seaport. Very destructive of highly skilled, blue-collar jobs in my opinion. Let's see if this will be operational when fossil fuel extraction, particularly oil extraction, starts declining and in a big way.

From The Guardian - Inside the London megaport you didn’t know existed
London Gateway was built by Dubai, is twice the size of the City of London, is run by robots, has the world’s largest cranes – and it’s where everything you buy will soon come from. London’s docks are back in business.

…Running almost 3km along the Thames estuary is a £1.5bn new megaport that has literally redrawn the coastline of Essex, and wants to make equally radical shifts to the UK’s consumer supply chain.

Welcome to DP World London Gateway, the latest international trophy of the oil-rich emirate of Dubai, and one of the biggest privately funded infrastructure projects the UK has ever seen. It is a gargantuan undertaking (on the scale of Crossrail, Terminal 5 or HS2) that’s projected to have a bigger economic impact than the Olympics – but you might not even know it was happening. The port has been up and running for almost two years, with two of its six berths now complete and a third well on the way.

As if this isn't already beginning to happen.

From ThinkProgress - This Is Your Brain On Climate Change
“We spend vast amounts of time and personal energy trying to calculate the most urgent threats posed by climate change. Washington, D.C. psychiatrist and climate activist Lise Van Susteren, however, says the most insidious danger may already be upon us. She’s not talking about heat, drought, floods, severe storms, or rising seas. She’s focused on the psychological risks posed by global warming.

 Van Susteren has co-authored a report on the psychological effects of climate change that predicts Americans will suffer “depressive and anxiety disorders, post-traumatic stress disorders, substance abuse, suicides, and widespread outbreaks of violence,” in the face of rising temperatures, extreme weather, and scarce resources. Van Susteren and her co-author Kevin Coyle write that counselors and first responders “are not even close to being prepared to handle the scale and intensity of impacts that will arise from the harsher conditions and disasters that global warming will unleash.”

http://thinkprogress.org/climate/2015/09/16/3701936/brain-on-climate-change/

And thanks to the developments in the Jet Stream that Jennifer Francis predicted, there is already climate warming amplification in the Arctic -- about 2x or more the global average temperature anamoly since 1880.

From Eureka Alert - Arctic mosquitoes thriving under climate change, Dartmouth study finds
HANOVER, N.H. – Warming temperatures are causing Arctic mosquitoes to grow faster and emerge earlier, significantly boosting their population and threatening the caribou they feast on, a Dartmouth College study finds.

The study predicts the mosquitoes’ probability of surviving and emerging as adults will increase by more than 50 percent if Arctic temperatures rise 2 °C. The findings are important because changes in the timing and intensity of their emergence affect their role as swarming pests of people and wildlife, as pollinators of tundra plants and as food for other species, including Arctic and migratory birds.

Well here's a good development which hopefully won't be adversely affected by peak oil. Check out the photo of the interior of one of the apartments: the poster on the wall is actually a site plan of the constructed apartment complex -- looks very New Urban.

Return of the prefabs: inside Richard Rogers' Y:Cube homes for homeless people
With riotously bright colours, Rogers’s ‘move-on’ housing scheme is dressed in the child-like garb of a My First House. But design niggles mean nothing to the tenants getting their own homes for the first time.

“I still can’t quite believe that the same architects who designed Terminal 5 and the Cheesegrater have designed my house,” says Wendy Omollo. “To have people as grand as that doing low-cost housing projects is really quite amazing.”

Omollo has been homeless since January, but this week she will join 35 others when she moves into the YMCA’s first factory-built “move-on” housing scheme, designed by none other than multi-award winning, international airport designing Rogers Stirk Harbour + Partners. While Richard Rogers’ practice graces this year’s Stirling prize shortlist for the sixth time, with the controversial Neo Bankside development and its £22m penthouses, it might come as a surprise to learn that a little further south, in the London borough of Merton, his office has just completed this scheme for a cost of around £45,000 per apartment, to be rented at less than the council’s affordable housing allowance.

Developed over the last few years in partnership with the YMCA London South West, manufacturers SIG and project managers Aecom, this 36-unit “Y:Cube” project is the practice’s latest foray into off-site manufactured housing, a dream Richard Rogers has entertained since his “Zip-Up” concept house in the 1960s – an unrealised fantasy of a modular pink prefab pod on stilts.
