Subsea permafrost is losing its ability to be an impermeable cap.

by Ginosar  

Over the last several years it became clear to some astute scientists that our slow and ineffective way we have been trying to curtail global warming is not going to slow significantly, if at all, the earth's temperature rise. The magnitude of GHG release is so large that we are likely to be too late to stop the severe damage to our limited Earth.

 

New information from the National Science Foundation [NSF] indicates that mass release of previously stored methane that we hoped will remain frozen has already started. And if we do not curtails drastically and very soon our global GHG this release of Methane would grow so fast and so large that the earth temperature would climb beyond nature's ability to sustain life as we know it. I suggest you read the NSF short report in the link below.

"The amount of methane currently coming out of the East Siberian Arctic Shelf is comparable to the amount coming out of the entire world's oceans," said Shakhova, a researcher at UAF's International Arctic Research Center. "Subsea permafrost is losing its ability to be an impermeable cap."

 

A section of the Arctic Ocean seafloor that holds vast stores of frozen methane is showing signs of instability and widespread venting of the powerful greenhouse gas, according to the findings of an international research team led by University of Alaska Fairbanks scientists Natalia Shakhova and Igor Semiletov.

 

The research results, published in the March 5 edition of the journal Science, show that the permafrost under the East Siberian Arctic Shelf, long thought to be an impermeable barrier sealing in methane, is perforated and is starting to leak large amounts of methane into the atmosphere. Release of even a fraction of the methane stored in the shelf could trigger abrupt climate warming.

Read my recommendations:

We must turn upside down our approach to fighting Global Warming because time is of the essence:


Instead of regulating Greenhouse Gases to a level that may have no negative economic impact, we must reduce GHG to the maximum that could be technically and economically implementable.
