Stalactites and stalagmites in Siberia have shown evidence of thawing, threatening a release of giga-tonnes of stored carbon.
Research conducted in caves in Siberia has suggested that a global temperature rise of 1.5 degrees could cause regions of permafrost to begin to thaw. Permafrost naturally stores carbon, and if thawed could potentially release 1000 giga-tonnes of greenhouse gases, greatly increasing the rate of global warming.
This release of gases would cause extensive damage to natural ecosystems and human environments.

I've been trying to explain to economists for some time that their 2 deg C target is pointless because permafrost thawing will be driving runaway warming well before 2 deg C.
Plan B, fellas: give up on this carbon derivative trading obscenity, set a fossil fuel consumption tax and increase it (with cuts in other taxes as appropriate) so as to totally eliminate fossil fuel use over the next two decades - the 90% decrease over 4 decades all you planners and highly paid consultants have been assuming is too little too late.

Don't think one can turn around our human 'momentum' that way David. The momentum builds on globally shared archetypes, of what a good life should mean, and of what being 'successful' should be. At the bottom it builds on greed and egoism as the 'forces' creating a change, to the better, for any and all individuals:)
I don't expect greed and egoism to step back for a globally united try to limit anything really, the best we can do is probably what we are doing at the moment, because anything real will cost you, and me.

Or put another way. Sure, we all want do what is right for the long term, but why should we be the ones to pay for it :)
We're not really equipped with long term planning abilities as I've noticed, but we are pretty good on adapting. So let's put some hope in our ability there.

We're not willing to pay for it?
My advocacy is for a fossil fuel consumption tax, which REPLACES other taxes: we no longer pay other taxes, but we do pay a tax on fossil fuel.
The more enlightened among us work out that to minimise their future tax bill, they use some of their present tax savings on low/zero emission technology and equipment. The less enlightened (more inert?) among us continue paying more tax until they figure it out, or die to be replaced by a generation who has grown up…

I don't know David, to my thinking any real effort stopping a global warming, need to stop the cars, and industries, using fossil fuels. I would like that and have said it loud several years ago, earning surprised looks from people wondering about my sanity :)
I don't think we will do that, instead we will go to a changing planet, and there a lot of species, and flora, must change their locations to survive. I don't think they will, or rather, some will, and if we just could leave them in peace…

Thanks Yoron. You and I are agreed that the world needs to stop using fossil fuels; I think the point on which we seem to differ is my optimism that the world will stop using fossil fuels sooner rather than later.
That the CO2 already emitted is already changing the world is beyond doubt, as is the expectation that much of this change is yet to come. That this change has been and will be detrimental is obvious when we consider that all life and human civilisation have optimised themselves to…

A good idea Arthur, and one never knows. You just might be right in your optimism. I'm slightly more cynical I'm afraid :) Doesn't mean I need to be right though. I prefer it the other way.

Oh, sorry, meant David :) unusual combination of names to me. Used to discuss with another guy , another site, named Arthur so I will blame it on that :)

It's a perfectly straightforward substitution of one enabling technology (fossil fuel use) with a suite of alternatives (solar PV, solar thermal, biofuels, wind, wave and tidal energy generation, even nuclear power).
No need to concern ourselves with archetypes of any sort - even revheads can keep their V8's if they're powered with fuel derived from plantation mallee.
