No 'Burp' Accelerating Climate Change - Wetlands Likely Source Of Methane From Ancient Warming Event (Scripps Institution of Oceanography)

An expansion of wetlands and not a large-scale melting of frozen methane deposits is the likely cause of a spike in atmospheric methane gas that took place some 11,600 years ago, according to an international research team led by Scripps Institution of Oceanography at UC San Diego.

The finding is expected to come as a relief to scientists and climate watchers concerned that huge accelerations of global warming might have been touched off by methane melts in the past and could happen again now.

More hysteria alleviated.
 
I see no evidence that a large-scale melting of frozen methane will not occur due to the current warming.

It merely stats that that one event 11,600 years ago was due to another process.
 
So accompanying the old "it has happened before and therefore isn't a threat" line, we now have the "it hasn't happened before and therefore isn't a threat" line.

And please don't forget that it is all a conspiracy by international communist scientists to bring down the US.

That's nice. Isn't it interesting how Poptech agree with Scripps Institute on this one issue and not the host of others concerning the support on AGW?

This is just absurd. No one is talking about any conspiracy just a lot of misplaced trust in climate models.

The other reports of Scripps not based on climate models support global warming and climate change they do not support AGW. I find it interesting you agree with scripps on other issues but not this one.

Do you understand that you are quoting the opinion of the writer who wrote the news piece and not the scientist who wrote the article that the news piece is about?

I had absolutely no idea so lets quote them.

"This is good news for global warming because it suggests that methane clathrates do not respond to warming by releasing large amounts of methane into the atmosphere," said Vasilii Petrenko, a postdoctoral fellow at University of Colorado, Boulder, who led the analysis while a graduate student at Scripps.

Hey Poptech:

"Methane from permafrost" is not the same as a clathrate burp. The former is already observed as part of normal, mainstream AGW. The latter is a worst-case scenario of an additional positive feedback that might occur as the Earth responds to AGW.

If this extra positive feedback is not expected to occur, that is good news---the existing AGW and its positive feedbacks are bad enough as it is.

Oh, my. Really, so one is not the other. No calthrate burp would be good but is not methane in permafrost.

My friend, people here know more about this subject than you ever will. You are making infantile errors, and should stop and listen. You might actually learn something.

Methane clathrates are crystalline cages of ice containing huge quantities of methane (167 liters per kilo, IIRC), under known conditions of pressure and temperature. Having talked to some of the leading scientists in the field, who are working on how to safely drill the stuff out of the continental shelf, I know it's been known for years that there is no real danger of big emissions due to global warming.

Methane emitted from melting permafrost are a result of the microbial activity in the large quantities of anoxic organic matter previously frozen in permafrost. These emissions are significant and documented.

Now, apologize for your arrogance, and you'll find that people here are actually quite open to educate you in the science, and quite eager to discuss the real questions that you might pose.

Or keep doing your clown act... either way it's ok with me.
