Nothing that mankind has control over is more likely to cause mass death than continuing to contribute to climate change
The most likely stable state the climate is going to end up in, compared to the interglacial we're in right now, is back into full glaciation.
There's no stable "hotter" state known (no matter the historical CO2 levels, which have been much much higher than we're projecting to ever reach) to science. The only question during an interglacial is whether the poles will be free of ice or not - and looking at the latest interglacial, the Eemian, we shouldn't be surprised if the arctic circle becomes ice free (still without any catastrophic effects whatsoever).
What do we need to do to get back into full glaciation?
Nothing. Absolutely nothing. Although - changing the albedo as proposed in the article might well bring us there sooner rather than later.
Caveat: This post reflects the current state of science accurately. Watch out for replies that don't.
