Serious ? - What happens when the permafrost melts fast due to GW?
I've heard it will release incredible amounts of toxic gases. Is this true? And what other effects might occur if this occurs?

2. water levels rise in the oceans?
what about increasing the amount of fresh water that pours into the N. Atlantic, thereby stopping the Gulf Stream?

7. and yes,
There is some nasty stuff in the tundra that will be released into the atmosphere, especially if the humidity remains high.

We may end up starting evolution from scratch.

10. The general trend of our atmosphere (with excess warming)...
...will be to return to a state close to what the atmosphere was like 100s of millions of years ago -- full of CO2 and methane, very hot, and possibly not really enough oxygen to breath comfortably

11. I believe there will be changes
but right now,most glaciers are drastically reduced and the interior ice in the Arctic Ocean has melted like 50% yet ocean levels aren't a whole lot higher.

So, I guess I don't know.

13. Not toxic, but certainly heat-retentive
The projections are that the melting frozen bogs in western Siberia (an area about the size of France & Germany combined) will release about 80 billion tons (more or less) of methane.

Of course, since methane is about 26 times as efficient at trapping heat as CO2 is, this will be the equivalent of about two trillion tons of CO2 entering the atmosphere in the space of a couple of decades.

Or, as scientists sometimes say, "Oops!"

14. Lots of methane...
Permafrost stores lots and lots of methane, which is 20x worse for global warming than carbon dioxide. While it stays frozen it's OK, but once it starts being released we're in trouble: The methane adds to the greenhouse effect, which warms up more permafrost, which releases more methane... you can see where that leads.

There's also a good few billion tons locked up under the oceans (google "methane hydrates") which is damn close to being released, as well.

The bad news is, this process has already started.
The good news is... err... well, we got Saddam! He was naughty!

Fun reading:

17. I think permafrost will release lots of methane. Which is CO2 causing.

18. To reverse the process you have to get CO2 into a form that will
take it out of play. I read somewhere that when the world was covered with tiny sea creatures with shells - the creatures would die and the shells would fall to the bottom of the ocean - and take some greenhouse gasses with them in the form of that shell.

19. there's enough methane trapped in the permafrost to increase
temps more than our fossil fuel burning has. there's also a good amount of organic matter that will degrade and release CO2. we're pretty f'ed if all that stuff melts.
