Nope. Chaos theory says very much the opposite, and our experience is tending to back chaos theory here. I mean yes what you describe would also be bad, but it's not that we're going to see. I can't speak to the thermohaline cycle: perhaps you're describing something that'll happen specifically in the depths of the ocean? Sounds bad. Up here where WE live, the possible extremes of weather are factors of chaotic energy, and small increases in global temperature will produce wider potential swings in weather behavior. So we are not at all going to see 'a lack of variety' and we're not seeing it now. We're seeing 'wait, WHAT' weather and it's only going to get worse. The challenge is surviving those energies. Never mind colonizing Mars or Venus, the challenge we'll face is clinging on to THIS planet, and a hell of a lot of people will end up not able to survive what's coming. And it's subcultures like Hacker News we'll depend on, for people who'll come up with the 300-mph storm windows etc. I own a house: I'm not thrilled at what's going on. I'm trying to work out what I've got to do in order to not be taken out by some kind of weather extreme beyond what we used to have when I was growing up.
