Ice age deferred stymies David Middleton at WUWT
Sou | 12:50 AM


Anthony Watts has posted another ice age article at WUWT (archived here, cached here). This time, instread of it being an "ice age cometh" article, it's an "ice age isn't coming" article. The WUWT article is by David Middleton, who is one of Anthony's pet deniers. He was writing about a new paper in Nature about how we've deferred one and may possibly defer two major glaciations. We're certainly going to perceptibly affect the climate for more than 100,000 years ahead.

It's been known for some time that we've deferred major glaciations
The fact we've deferred at least one glaciation won't be news to anyone who's familiar with previous work on the subject. The fact we may have deferred two might well be news, although mathematician and astronomer Sir Robert Ball predicted it would take 200,000 years way back in 1906:

Speak no more of the glacial epoch as 80,000 years agone. The glacial epoch is ahead. Sir Robert Ball says that the next ice age is due in 200,000 years. In the course of long periods the earth's orbit round the sun changes from being nearly a circle, as it is now, to a long ellipse or oval, and in the last case the summer may be only 166 days long, while the winter lasts 199 days. There is a short hot summer, followed by a long, excessively cold winter, so that more ice is formed in the cold than can be melted in the warm season.

On purely astronomical grounds, even if geologists had not discovered the ice ages from the records of the globe's surface, astronomers would have demonstrated that ice ages must have happened. When the next chilly epoch arrives posterity may see all Northern Europe under an ice-cap that will o'ertop the highest mountains and last for many thousands of years.
