Yeah, that's one of the ones I freak over. It seems like the permafrost is thawing pretty rapidly. The climate maps are out there, the places that are warming most seem to be the frozen northern continental mass. Don't know about the ocean hydrates, I really hope the deep ones are under enough pressure and shielded enough that they will remain stable. I try talking about this sort of stuff, nobody wants to talk about it. Like at all. It's like people are living in some mass manufactured delusion. "But don't you think things have always been changing?" GRRRRR
Another things that may be worth mentioning while we're talking about the possibility of environmental effect, which I almost never hear mentioned, is the 'phase change effect'. I never got passed basic physics, but that I remember.
See it takes a whole lot of energy to get water to change phase from solid to liquid, once it is liquid the same amount of energy nets you a whole lot more warming.
Is it time to start shutting down the industrial economy yet?
I wasn't an oil or fracking chemical engineer. I was in the biofuels and bioethanol R&D industry. I discovered how unsustainable industrially produced biofuels are. After that discovery I had to leave to pursue true sustainability.
If it makes you feel any better, sea level rise is a negative feedback on methane release -- higher sea level means that the methane clathrate is under more pressure, which pushes the equilibrium back to the clathrate side of the reaction. Somehow though, I don't think we are going to get enough pressure soon enough to balance out the effect of warmer temperature. Ooops!
As far as the phase change effect, I point that out (to any that will listen) that after the Arctic Ocean goes ice free, there is going to be a LOT more heat looking for things to warm up. That's why I follow the PIOMAS volume measurements:
The problem as I see it is that the human race has come so far in terms of technology, something that previous civilisations didn't have, that we rely on so heavily that when eventually some thing in the chain breaks we have further to fall as a species than anyone that went before us. that's why I prep, I don't know what coming but its not going to be good and I want to be ready when it arrives. if nothing happens then fine I've got some resources that can be shared out after my death but I would rather be proved wrong than proved right.
Oh the stink of it! Smell my tiny ad!
