Seismic signs of escaping methane under the sea
NATURE NEWS ^ | 25 October 2012 | Virginia Gewin

A changing Gulf Stream is warming deep waters along the eastern United States and destabilizing greenhouse gases trapped in sediments.

Somewhere off the eastern coast of North Carolina, a frozen mixture of water and methane gas tucked in seabed sediments is starting to break down. Researchers blame a shifting Gulf Stream — the swift Atlantic Ocean current that flows north from the Gulf of Mexico — which is now delivering warmer waters to areas that had previously only experienced colder temperatures.

“We know methane hydrates exist here and, if warming continues, it can potentially lead to less stable sediments in this region,” says Matthew Hornbach, a marine geologist at the Southern Methodist University in Dallas, Texas, who led the study that is published online today in Nature1. The results suggest that the warmer temperatures are destabilizing up to 2.5 gigatonnes of methane hydrate along the continental slope of the eastern United States. This region is prone to underwater landslides, which could release the methane, a powerful greenhouse gas.

Whether that methane would make it to the atmosphere and worsen global warming is unclear, but scientists think that it is unlikely. “We don’t need to worry about any huge blow of methane into the atmosphere,” says Carolyn Ruppel, a geophysicist at the US Geological Survey in Woods Hole, Massachusetts. Rather, she says, Hornbach and his co-author Benjamin Phrampus, also of the Southern Methodist University, have uncovered a powerful new way to use data from the geological record to catch non-anthropogenic climate changes that are already happening...

And whom are they blaming for shifting the Gulf Stream?

smokingfrog : “ ocean farts “

At 25 X destructive to ozone as are carbons, methane is a force to be recconed with .
You don’t mean to suggest that nature releases methane contrary to Al Gore’s taxation of “C(r)ap and Trade “ ?
Do you mean to suggest that Uncle Al Gore would be willing to trade Carbon credits and make a profit , do you ?

Sacrifice the planet to make a monetary killing ? /sarc

There are already reports of methane bubbleing through puddles in the warming permafrost in Sibera.
Perhaps we should tax the Russians into submission ?

Text near the top, where people skim just to get the jist of the article:

A changing Gulf Stream is warming deep waters along the eastern United States and destabilizing greenhouse gases trapped in sediments.

Researchers blame a shifting Gulf Stream — the swift Atlantic Ocean current that flows north from the Gulf of Mexico — which is now delivering warmer waters to areas that had previously only experienced colder temperatures.

The rest of the story, after all the skimmers are runnng away screaming in panic:

“We know methane hydrates exist here and, if warming continues, it can potentially lead to less stable sediments in this region,” says Matthew Hornbach, a marine geologist at the Southern Methodist University in Dallas, Texas, who led the study that is published online today in Nature1.

Wonderful, balanced article. Yes, they can claim they put the doubtful parts in, but way after they used hysteria to hype the paper, down in the parts of the article fewer people read.

Not funny if you ship is in the middle of one. Straight to the bottom without a clue of what hit you.

There’s something under the Outer Banks...and it’s farting.

So, the sea floor is flatulating. Harvest it.

WHAT??!! You mean... the climate changes even if we don't drive our SUV's around? (/sarc)

Mea culpa.

If only I had changed lightbulbs sooner, this would never have happened.

Puleeeeeez......I have a circa 1850 book that has a whole article on this methane/ocean occurence. It is nothing new.

No kidding. “Somewhere off the eastern coast of North Carolina...”

They have a western coast? Who knew?

http://curiosity.discovery.com/question/how-was-methane-hydrate-discovered [snip] It wasn’t until the 1960s that methane hydrate was discovered as a naturally occurring element. Scientists first discovered the solid natural gas in a gas field in western Siberia. In 1982, scientists retrieved a deep-water sample near the Guatemalan coast that helped spark U.S. research and development into methane hydrate as an energy source. [/snip]

The piece sounds like grant fishing to me. Screw around at sea, write about a hypothesis, use that for the basis of a grant application

How about granting ourselves the right to harvest that methane?

If I recall correctly, far more methane is produced by microbes under the ocean than on land, the vast majority of all photosynthesis and respiration on Earth also occurs in the ocean as well. Last time I heard, there’s still plenty about our oceans and water-filled caverns left to be discovered.
