You have that backwards actually. It is the increasing temperatures that is causing the permafrost to thaw, and in return that is releasing the trapped methane. It is certainly not the methane melting the tundra.
I have it right. There's going to be a lot of methane released, as tundra melts. I can't think of a neat way to capture it (without killing all the vegetation there) but give me a few million and I could probably think of something.
There's an equivalent problem with the sea bed: methane clathrates are ice cages with methane 'guest' molecules, that rely on cold AND water pressure to keep from breaking apart and releasing the methane. There may be bacterial life involved too, but the prospects for methane 'harvesting' are much better. A sea bed crawler could warm a patch, or temporarily decrease its pressure, releasing methane up a pipe to be liquified on a ship. (Not liquifying it would be better, but a floating pipe back to land would rather limit the range of the machine.)
Why is it the ONLY solution AGW fanatics have is to massively increase taxes on everyone? That tells me immediately that AGW is nothing more than a scam by Marxists who is using AWG as a vehicle for redistribution of wealth.
I think you spat up a furball. You probably shouldn't eat so many Marxists, my friend.
I'm not an AGW fanatic, nor did I specify a "massive" carbon tax. All that's necessary is to shift the burden of taxes (for instance the anti-jobs FICA tax could go) to encourage the sort of economic behaviour which is low-emissions. At the very least we could stop SUBSIDIZING fossil fuels, and if the Canadians want to pipe in even more filthy polluting muck that is practically illegal in Canada, maybe they could BUY the land instead of begging for eminent domain.
A carbon tax, just on fossil fuels, is less than ideal. The agriculture (particularly dairy) emissions are pretty huge, and a nominal tax is necessary there to get producers planning for low-emissions breeds and low-emissions feed. Government should also endorse a system of offsets, for the public to voluntarily buy into or to prefer products with offsets. That's typically reforesting marginal farming land, but also re-establishing mangroves. It could even be 'negative' offsets, with benefits going to loggers who use more expensive but less wasteful methods, farmers who protect their soil better at the cost of lesser yields.
Yes I'm in favor of tax. Anyone who is opposed to tax in every case, is as ridiculous as a character out of an Ayn Rand novel. WHAT is taxed is a matter for active minds, and brave people who aren't afraid of hurting any industry when they're going to get hurt pretty bad just carrying on like they are. Ten years from now, the coal industry will be begging for government help. "Buy our beautiful coal, there's nothing wrong with it. Fill in the Grand Canyon or something, we don't care, just buy the coal!"
