Not good news that was written off almost as scientific curiosity when it happened in August: methane blow holes found in Siberia. Here's a Huffington Post article about it from August. The indication is that this is both caused by climate change and an almost immediate trigger for more instability and probable kick off for an ice age. Here's yesterdays news where at least 20 more blowholes were just spotted: More Siberia methane blowholes found in permafrost. Thoughts? Reactions? I guess an underlying question here has to do with how in an era of certain catastrophic climate instability, socio-political destabilization, continuing economic crisis, gold-rush style energy bubbles, and the like there's an increasing insistence on the part of anarchists and even "green anarchists" to take a hardline relativist position? I get that this is scary stuff. I get that there are issues with science, but this is where philosophical underpinnings should die: melting permafrost creating methane blowholes is objectively a bad sign.

This is a strong sign that we've reached irreversible tipping points towards abrupt climate change. Forecasts for 6 to 10 C global average temp rise above preindustrial levels by the end of the century seem increasingly likely. This is a scenario that will certainly collapse civilization, but also makes any human existence doubtful, especially considering scenarios involving nuclear meltdowns.

I appreciate you embracing the vibe of the thread, but, on a personal level, I could have taken that kind of news much better from "fetalpink" than "northernfrostbite".

Perhaps the biggest near term tipping point is melting Arctic ice cap, which the US Navy has predicted will be gone for a period of time next year.
Now let me drop some physics....
It takes 170kj of energy to bring 1kg of ice from -100C to 0C. It takes 334kj of energy to melt 0C ice to water. With 334 kj of energy, 0C water heats to 79.5C
In other words, once we reach that point where the Arctic ice is gone for a brief period, the Arctic will quickly heat releasing gigatons of methane 40x more powerful than CO2.
I've contemplated a trip to the Yamal Peninsula just to see the end of the world firsthand, but I'm not sure what good it'd do.

We will most likely see the extinction of our species in our lifetime, some think as early as 2030. youtu.be/QGBy889jXIg

I dunno, I sort of think Guy McPherson is a bit of a quack. But if everything is going to shit in 15 years, it's not like he'll have a lot of time to gloat.

I dunno, I just went down his rabbit hole some months back and find that he is way too confident about his predictions and science, and other scientists have questioned his premises. I am not saying that things aren't awful and would get bad really soon, but to give us fifteen years seems a bit too prophetically apocalyptic.

Well maybe, but considering the fact that the Arctic might be ice-free this or next September and that it will be the first time during the existence of our species, I think he has reason to be apocalyptic. Another must-see video on the subject; youtu.be/a9PshoYtoxo
