use permafrost in a sentence.
Is that the "permafrost" Stevey wrote about?
In what way is Python torpedoed or permafrosted?
Methane asphyxiation due to global thawing of permafrost.
There's plenty of evidence, other than temperature measurements: permafrost, glaciers, and polar ice melting; extended growing seasons; changes in bird migration.
Mars continues to have large amounts of water ice in the form of sub-surface permafrost across most of the planet.
I don't know that that works - the south pole at least has ground, and a LOT of permafrost that isn't displacing any water.
Canada may be a big winner from climate change but it won't be because of permafrost.
Title doesn't match the article:"Permafrost areas hold 500 billion tonnes of carbon, which can fast turn into greenhouse gases," Zimov said.
Hope this doesn't start the joke of "the cpus run so hot they melt the permafrost.
I see lots of evidence of global warming: Arctic sea ice melt, permafrost melt, growing season lengthening, earlier bird migration, bird overwintering, animal range changes, etc.
Also permafrost is melting (irreversibly on human time-scales):
Not to mention the melting of the permafrost, glacial retreat and the fact that Arctic ice levels are (yet again) reaching historic lows:Theories of anthropogenic global warming pre-dated and predicted all of these developments.
I was struck by the "climate does not matter" part - I have always assumed Canada will be one of the 22nd century's big winners in climate change terms (lots of nice melted permafrost agricultural land and an extra 6 degrees would be balmy)the upshot of this is I assumed land north of Toronto is always going to be a good buy for grand children.
In places where the ground is frozen permanently (permafrost), i.
The other thing to consider is the effect of heating permafrost, which is well-known.
Given that there is nothing wrong with the science and the fact that mankind can't even manage to stop the smaller-scale climate change that we thought we'd have to face, I fail to see how something like thawing permafrost - which will make the problem much worse, much quicker - can possibly be described as something other than a catastrophe.
