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!

Fires Rapidly Consume More Forests and Peat in the Arctic

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

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 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."
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 carbon dioxide (CO2) and methane as it warms and decomposes.
