“Improved drainage results in a drier landscape over a decadal timescale, and the process then becomes self-limiting,” said Scott Painter, who leads the Watershed Systems Modeling group at ORNL.

Claim: Permafrost peatlands approaching tipping point
Researchers warn that permafrost peatlands in Europe and Western Siberia are much closer to a climatic tipping point than previous believed.
Thawing Permafrost Could Leach Microbes, Chemicals Into Environment
The hope is that using measurements from a combination of platforms will help scientists create a fuller picture of changes at the poles, where permafrost is thawing the fastest.
Monitoring Arctic Permafrost with Satellites, Supercomputers, and Deep Learning
“The ice wedges form from the freezing and melting of soil in the tundra,” said Liljedahl. “Some of them are tens of thousands of years old.”
Claim: Permafrost carbon feedbacks threaten global climate goals
From the PNAS Abstract Rapid Arctic warming has intensified northern wildfires and is thawing carbon-rich permafrost. Carbon emissions from permafrost thaw and Arctic wildfires, which are not fully accounted for…
Claim: A groggy climate giant: subsea permafrost is still waking up after 12,000 years
In the far north, the swelling Arctic Ocean inundated vast swaths of coastal tundra and steppe ecosystems. Though the ocean water was only a few degrees above freezing, it started…
We still Have a Chance? Norwegian Climate Doomsday Authors Issue a “Clarification”
A few days ago WUWT reported on a Norwegian “past the point of no return” global warming paper whose outlook was so pessimistic even climate alarmists were upset. The authors…
The Arctic “Death Spiral”: Lamenting the Collapse of a 4000 Year Old Ice Shelf
The Guardian wants you to weep for an ice shelf which even they admit didn’t exist back when the Egyptian Pyramids were being constructed. They demand we do everything in…
Alaska is getting wetter. That’s bad news for permafrost and the climate
Alaska is getting wetter. A new study spells out what that means for the permafrost that underlies about 85% of the state, and the consequences for Earth’s global climate.
Nitrogen in permafrost soils may exert great feedbacks on climate change
Institute of Atmospheric Physics, Chinese Academy of SciencesShare Print E-Mail What nitrogen is getting up to in permafrost soils may be much more interesting than researchers have long believed–with potentially significant consequences…
How horses can save the permafrost
New mitigation strategy bears great potential University of Hamburg Permafrost soils in the Arctic are thawing. As they do, large additional quantities of greenhouse gases could be released, accelerating climate…
NASA Flights Detect Millions of Arctic Methane Hotspots

NOAA Ecologist Re-arms Debunked Arctic Carbon Time Bomb
Guest slam dunk by David Middleton From the “I couldn’t make this sort of schist up, if I was trying files”… Scientists feared unstoppable emissions from melting permafrost. They may…
No laughing matter
From The Harvard Gazette The warming Arctic permafrost may be releasing more nitrous oxide, a potent greenhouse gas, than previously thought By Caitlin McDermott-Murphy Harvard Correspondent DateJune 6, 2019 About…
Another example of clear failure of IPCC models to predict reality in the AR5 draft
One of the regular alarm stories that comes from the global warming machine is that atmospheric methane with soon run amok and cause a tipping point. We are regularly treated…
