New research on Arctic methane

[PeterS]

You have no proof whatsoever that we can slow down climate change.

Proof? Do greenhouse gases warm the planet? If they do and we emit less wouldn't it follow that we would slow down climate change?

 

[Old Rocks]

That's an unsupportable and unprovable position. The thing people need to realize about climate change is that we don't understand any of it well enough to make these sorts of assertions.

You are simply wrong. The present of effects of the increase in GHGs was actually predicted over a century ago by Svante Arnnhenius. The statement concerning the 50 year period is based on ocean effects that we have observed. Once again, here is a site where you can read what the real history is concerning the science and CO2;

The Carbon Dioxide Greenhouse Effect

We created the present warming by putting GHGs into the atmosphere. If we have not passed the tipping point where natural processes lead to an outgassing of the clathrates, we can cease to put more GHGs into the atmosphere than natural processes remove.

I have been making the argument for some time now that "Methane" is being released into the Earth's weather system,thus expediting Earth Cyclical Climate Change".
There have been a few posters that did not believe this Methane component, with regards to the Earth Climate change situation.

The Carbon Dioxide Greenhouse Effect

You are either being dishonest or you are confused. No one is talking about the existence of the greenhouse effect with respect to carbon dioxide or other gases, which is well-established. We're talking about making the leap from that to explanations of climate change and even predictions of climate change based on incomplete (and incompletable) computer models.

Anyone who says they know with certainty that the anthropogenic effect is the dominant factor in climate change is selling something.

I saw a report on television where researchers in the artic showed methane bubbling from the bottom of a lake in Alaska. It was an amazing thing to see. There was a constant stream of gas bubbling up to the surface.

its happening off the east coast as well

Yes, very incomplete models. Models that have so far been far to optimistic. The rapid diminishment of the Polar ice was not in the models. The start of the outgassing of the ocean floor clathrates was not in the models. What I am talking about is not models, but what is happening right now in real time. The predictions of climate change because of the warming caused by the GHGs is not from models, but from past events in the Geological record.

No, anyone that cannot see that you cannot put nearly 40% more CO2, and over 250% more CH4 into the atmosphere without major results is blind. There has been no increase in volcanic activity, no increase in solar irradiance for the last 50 years, so what is left? Really, you should do some research into this subject;

These are common and nothing new.

yup
been happening for eons
and there isnt a damn thing we can do about it

ATMOSPHERIC concentrations of methane, "a greenhouse gas more than 20 times more potent than carbon dioxide", have risen for the first time in eight years, prompting concern about the pace of climate change.

A global study in Geophysical Research Letters found the first increase in methane levels this century — by about 28 million tonnes since mid-2006 — was in part due to release of gas in and near the Arctic.

CSIRO senior climate scientist Paul Fraser said the data was in line with predictions that rapid melting of Arctic ice would create natural wetlands, one of the most common methane emitters. "This is not good news for global warming," he said.

Over the past decade, methane emitted from wetlands, rice fields, cattle, bushfires and coalmines had been largely offset by absorption of the gas by dry soil and through atmospheric oxidation, Dr Fraser said.

"Over the past year, the total sources have overwhelmed the total sinks and methane has started to rise," he said.

Methane is estimated to be responsible for about 20% of global warming since the Industrial Revolution.

The published study comes after British newspaper The Independent reported that scientists aboard a Russian research ship had found millions of tonnes of subsea methane was bubbling to the surface and being released into the atmosphere off the Siberian coast this northern summer.

Don't light a match, Kirk.

Well, we might consider capturing it for a domestic natural gas source.

that had been proposed, but the enviro wackos protested

What a coincidence---I just invented a methane collector !

Want to get in on the ground floor ?

I saw a documentary were scientist cut a pice of Ice from a lake in either Iceland or greenland, and there was so much methane in the ice,that when they put a flame to the ice the entire pice of ice ignited into flames.!

This bit is unpublished and completely sensationalistic, not too surprising given that it was in the Independent.

Good thing you didn't ask me to get in on the bottom.

Hmmmmmm--would that have worked ?

Look up methane clathrate on google. Not ussually found in surface ice, but rather in ice pods and layers in the sediment of the ocean floor on continental shelves.
