More bomb throwing...............

Microbes eat 90% of methane on the ocean floor!!!

Surprise Life Discovered Inside Deep-Sea Rocks

The AGW community doesn't want you to know that!!!

Blowing up these threads is getting to be so easy, frankly, its getting boring!!

The distribution of methane on the Siberian Arctic shelves Implications for the marine methane cycle - Shakhova - 2005 - Geophysical Research Letters - Wiley Online Library

[1] The seepage of methane (CH4) through the seabed of the world's shelves is considered to be ubiquitous. Although numerous observations of methane seepages from shallow marine sources have been reported, there were only a very few observations made over the Arctic shelves and none for the East-Siberian Sea (ESS) or Laptev Sea (LS). We present two years of data obtained during the late summer period (September 2003 and September 2004) for both the ESS and LS shelves. According to our data, the surface layer of shelf water was supersaturated up to 2500% relative to the present average atmospheric methane content of 1.85 ppm. Anomalously high concentrations (up to 154 nM or 4400% supersaturation) of dissolved methane in the bottom layer of shelf water suggest that the bottom layer is somehow affected by near-bottom sources. Considering the possible formation mechanisms of such plumes, we favor thermo-abrasion and the effects of shallow gas or gas hydrates release.

Supersaturated by 2500% at the surface.

You can see the increase in methane in the last few years in this video.

Methane is like adding 100PPM of CO2 to the atmosphere and we already know that an additional 100PPM of CO2 has no effect on temperature or climate

More Arctic Methane Bubbles into Atmosphere - Scientific American

There, the underwater permafrost serves as a cap over methane in the seafloor. The permafrost is thawing, though and losing its ability to hold in the methane.

"Thus, methane could release in large amounts," Shakhova said.

In deeper parts of the ocean, the methane released from the ocean floor would likely never make it up to the atmosphere, since it would get used up by microbes before it reached the surface.

However, on the shelf where Shakhova measured methane releases, the shallowness of the sea and the fact that methane is released as bubbles mean that it rises quickly to the surface and escapes into the atmosphere.

Storms bring up more methane
Pulses of the methane bubbles are often triggered by storms, which churn up the water and allow the bubbles to quickly make their way up to the surface, the study found. Storms are already common in the area and may increase with climate change, leading to more methane pulses.

Shakhova's research team used sonar to target bubbles of methane rising up from the seafloor. They calculated the amount of methane being released from the bubbles to the atmosphere at 17 teragrams per year, which is close to the amount being released from the Arctic tundra.

More plumes observed in the Arctic Ocean breaking surface in 2014.

so what? Where is today's numbers?

How the fuck is Manmade global warming melting the undersea permafrost?

Good fucking grief, you Cultists believe ANYTHING

Let's stop the undersea volcanoes!

Because warmer temps melt things.

Dear god, you are one stupid cultist.

I know that's understood by everyone, but it needs to be reiterated, especially when you say things that are so 'effin stupid. You're so bleedin' dumb, you failed to grasp the connection between "warming" and "melting".

Imagine that.....CO2 can make frozen things melt even when the environment they are in is still below freezing. CO2 can apparently even change the temperature at which things freeze... Guess that is how the warming = freezing thing works...That would seem to lead to the idea that drier = wetter and all the other craziness one must swallow if one is to be an AGW cult member in good standing.

Right like it caused avalanches on Mt. Everest

Robot gliders see how Antarctic ice melts from below

By Becky Oskin
Published November 11, 2014
Scientists suspect Antarctica's shrinking glaciers are melting from the bottom up, and a fleet of robot ocean gliders may help explain why.

Beneath the icy Weddell Sea in West Antarctica, the gliders discovered turbulent warm currents near ice shelves, the huge floating platforms where continental glaciers extend icy tongues into the sea. The swirling eddies carry pulses of warm water to the shallow depths underneath the ice, scientists report Nov. 10 in the journal Nature Geoscience.

"What we're looking at is delivery of heat right up to the ice shelf, where the ocean touches up against the ice," said lead study author Andrew Thompson, a physical oceanographer at Caltech. "It's almost like a blob of warm water, a little ocean storm."

[Album: Stunning Photos of Antarctic Ice]

Previous work already pointed to warm water rather than hotter air temperatures as the reason for Antarctica's retreating ice shelves. (The disappearing ice is part of the continental ice sheet, not the sea ice that freezes and melts each year.) But to confirm these suspicions, the researchers needed to get under the ice to see how the process works.

In 2012, Thompson and colleagues from the University of East Anglia, in the United Kingdom, used remotely operated gliders to probe the ocean conditions near ice shelves in the Weddell Sea. The gliders rise and sink without propellers, relying instead on a battery-driven pump that changes their buoyancy via a fluid-filled bladder. Every few hours, the six-foot-long glider surfaces and uploads its data via a satellite phone network. The gliders collected temperature and salinity data for two months, exploring the upper 0.6 miles of the ocean.

When the gliders hit an eddy, the sleek yellow robots were often caught up in the powerful vortices. "You could almost know by where it came up that it had hit this anomalous region," Thompson told Live Science. "The glider would go down and end up in a quite different place."

The findings are the first to explain how warm water rises from deeper levels to reach the floating ice shelves. The results suggest the stormlike currents bring up pulses of warm water, which flow under the ice at irregular intervals. Now, researchers need to find out what happens when this heat reaches the grounding line, the spot where glaciers transfer their weight from the continent to the ocean. This is where most of the melting takes place, Thompson said.

"What we're seeing from the gliders is that it's not a steady circulation in and out," Thompson said. "This is really the first step of understanding of what heat goes in, and how efficient that heat is in melting the ice shelves."

Alternating layers of cold and warm water surround Antarctica, and it only takes a few degrees of difference to dissolve a glacier. The warmer water is typically in the middle layer of the ocean. It arrives from the north, delivered on a giant current called the global conveyor belt. Colder water lies on the surface, often formed when cold wind blows over the ocean and sea ice freezes up. Dense, cold water is also on the ocean bottom.

Dear god, the deniers here are stupid people. They just keep piling on with these ever more flamboyant displays of stupid.

It's much like a queer pride parade by the deniers, except it's a stupid pride parade. Frank and jc and SSDD on a parade float, screaming "WE'RE STUPID AND IN YOUR FACE!".

So I'm curious, when a volcano erupts under water, does the water around it become warm or cool? I'd like you positionon this. Thanks

jc, instead of your endless idiot questions, try to locate your balls and state an actual point. Like this simple point, which is that you're doing your cult buttboy routine of trying to disrupt every thread with dishonest babble.

It's been pointed out to Frank before that avalanches occurred on the lower slopes of Everest where temps go above freezing. He ignores that fact, and chooses to claim temps never go above freezing. Frank, being you're such a flagrantly dishonest POS, why should anyone ever speak to you? After all, you'll just lie in return, because lying is what cult buttboys do best.

Well, we give them articles from real scientists, and their reply is idiocy.
