This wiki article have many links: https://en.wikipedia.org/wiki/Runaway_climate_change
But I would like to clarify my position: I am not a climatologist and can’t independently evaluate these claims on math level, but I understand their logic and think that while runaway climate change is low probability event, we should do more to prevent it.
The interesting point is similarity between two communities. The community of people who think that self-improving AI is possible and is x-risk and community of people who think that runaway warming is possible and is x-risks. The most interesting thing is that both communities choose to ignore each other. But the mechanism of risk (positive feedback) and timeframe (2030) is almost the same.
I checked the timeframe in Arctic-news.com. They said that things will become serious after 2030, but extinction will happen around 2060. It is shown on last graph in http://arctic-news.blogspot.ru/p/the-mechanism.html
As I remember the LW census, it put AI on 2060? Could you remind me exact data?
I fail to see the difference. Of course, if we take into account possible space colonies it will not be extinction…
Also the article speaks about “which refers specifically to climate changes that cause a planetary body’s water to boil off”. I don’t think it is survivable.
Also runaway global warming is (relatively) easy to prevent by the means of geo-engineering.
May be it will be highest mountains after 7000 meters, which will turn from − 50 to +30 C.
Wiki said that threshold for water runway warming is 47 C (at 10 per cent high solar luminosity) and if it reached, the temperature will reach 900 C in new stable state. https://en.wikipedia.org/wiki/Future_of_the_Earth#Loss_of_oceans
It means that very hot earth where small highlands will still be habitable - is still in unstable condition and could have much higher global warming.
Could you point me to an article that specifies that this would actually race temperatures to Venus levels?

That article says:
That would be really bad but it’s not the same as total extinction.
I don’t think that’s the timeframe of the LW community as shown by our census.

(in the form mean + stdev (1st quartile, 2nd quartile, 3rd quartile) [n = number responding]))
From 2013:
Singularity year: 1.67E +11 + 4.089E+12 (2060, 2090, 2150) [n = 1195]
From 2014:
Singularity: 2143.44 + 356.643 (2060, 2090, 2150) [1177]

Most of the planet being uninhabitable means that there are still part of it that are habitable.
