Ice doom of DOOM!

[james_davis_nicoll]

The previous ice age lasted some 110,000 years and ended about 11,000 years ago. In other words, some 4,000 generations of humans knew of nothing but harsh winds and eternal snows. The apparently "normal'' periods between ice ages, like the present one, have averaged between 8,000 and 12,000 years. In short, the next ice age is overdue. The key question is when it will come. Can space be colonised by a sufficiently large population so that, when the next ice age strikes, it will not threaten the survival of the race?

Not only do the modern models attribute the cooling for the 1940s-70s to aerosols, so did the work in the 1970s. One thing I have to repeatedly point out to the "they forecast an ice age in the 70s" crowd is that that minority[1] of forecasts were all based on high-aerosol emission scenarios.


[1] There was a period of a couple months where the cooling forecasts caught up to the number of warming forecasts. It ended when the third paper forecasting warming came out.

I assume somebody is now campaigning for increased aerosol production but I haven't encountered them.

It's a common idea for geoengineering. Would apparently be pretty cheap and easy, within the reach of a dedicated billionaire.

We know what Elon Musk, Tony Stark, and Bruce Wayne are doing with their money. What about the rest of them?
