Abrupt Permafrost Thaw Underway

Rapid Permafrost Thaw Unrecognized Threat to Landscape, Global warming Researcher Warns,
University of Guelph, April 30, 2019.


New Threat
Rapid Vs Expected Slow Collapse
"...rapid collapse of permafrost that can transform the landscape in mere months through subsidence, flooding and landslides."

Sleeping Giant
Awake Now
"We are watching this sleeping giant wake up right in front of our eyes."

Scope of Permafrost Problem
"Permafrost affects about one-quarter of land in the northern hemisphere."

"...permafrost region soils now hold twice as much carbon - about 1.6 trillion tonnes -- as is contained in the atmosphere."

Rapid Wholesale Transformation
"...our field sites are being destroyed by abrupt collapse of this ice, not gradually over decades, but very quickly over months to years."

"...wholesale transformation of the landscape that not only impacts carbon feedbacks to climate but is also altering wildlife habitat and damaging infrastructure."

Doubled CO2 Feedback Trouble
"It's happening faster than anyone predicted. We show that abrupt permafrost thawing affects less than 20 per cent of the permafrost region, but carbon emissions from this relatively small region have the potential to double the climate feedback associated with permafrost thawing."

"...abrupt permafrost thawing disrupts deeper carbon stockpiles more rapidly. In addition, abrupt thaw releases more methane -- a stronger greenhouse gas than carbon dioxide -- than does gradual thaw."

Full Speed Ahead
As Much, "Growth" as Possible
"There is an urgent need to make substantive progress on representing the effects of abrupt thaw on the carbon cycle in Earth system models. This will inform policy-makers about how the release of carbon from abrupt thaw may affect the implementation of carbon management strategies to control the growth of greenhouse gases in the atmosphere."

Bottom Line

Climate Model
Climate models cannot keep up with our rate of CO2 production,
and its associated rates of climate and ecosystem degradation.

Worse models the Best?

Two Degrees Already Baked In

Improved Models Show Grim Future

Four Degrees by 2084


This thing's off the hook.

Support Tahoe to Whitney

The Tahoe to Whitney Trail Guide and Magazine are walked, written, funded, and supported by my efforts, with the help of kindred spirits and my sister.

We offer valuable Trail Guide, Skills, Weather, News and Analysis.

My goal is to get you out to see your natural and social potential. Help me keep this unique resource accessible and expanding towards its potential. We've a lot of miles to cover ahead...

If you feel these efforts are valuable, I'm cordially inviting you to support them, here:



I am currently working towards publishing the completed guide between Tahoe & Yosemite as an e-book, while converting this "blog" to a fine magazine format. You will like the results! Help Tahoe to Whitney reach its potential!
