>Melting permafrost in tundra regions like Alaska releases methane: more warming
If it makes you feel any better, the methane disperses in about 12 years. So a bunch of animals will become extinct and then 12 years later everything will go back to normal!
Yeah it doesn't make me feel good either.
- dv_dt 10y agoI don't think that's a great model, in 12 years, lot's of the biosphere could die off, generating more methane in decay.
- astrodust 10y agoThat could be twelve years of utterly apocalyptic weather we might not survive. Just saying. Nobody knows how bad that could get, but do you think we could survive over a decade where the outdoor temperature is, on average, 200°F? One of those animals could be the human species, or at least our idea of what that represents.
- zaroth 10y agoWhat is this nonsense? The worst case models predict a 10-20 degree increase by 2100.
- flukus 10y agoThe models don't rely on the silly assumption that all the permafrost would melt and release it's methane instantly.
- astrodust 10y agoA) That's 10-20°C, not °F. We're already seeing temperatures of 120°F (49°C) in parts of the world, so another +20°C puts that at 156°F (69°C). I'm not exaggerating all that much. B) The projections keep getting more pessimistic as more data is accumulated. C) We're talking about the theoretical worst-case scenario where everything spirals completely out of control and Venus starts to look like a temperate climate.
- triplesec 10y agoDo you have any sources for that 12 years datum? It's a new one to me.
- flukus 10y ago> So a bunch of animals will become extinct and then 12 years later everything will go back to normal! It's not going to suddenly release all in one day. And it can/will trigger further feedback loops.
