2.5 million years ago, and it’s still Bush’s fault.

My understanding was that ice ages are cyclical due to a pattern of variation in Earths orbit around the sun.
To: AndyTheBear
I was under the same impression...but I believe, it is also connected to the joining of north and south American changing the ocean flow.....

Ok, so why is the article even talking about “the” ice age...as if there were only one?
To: Renfield
So I guess meteors have more or less regularly been hitting the earth every 100,000 years or so to cause the alternating glacial periods separated by a 10,000 or so interglacial warm period.

Even at the height of this GLobull Warming hysteria, the sad irony is that no one ever mentions the fact that we are still in an Ice Age - albeit an Interglacial Warm Period.

The ice ages appear in cycles. But this isn’t speculating about why they have a cyclical nature, but rather what caused the first cycle.
Much more convincing as a cause was the discovery that ice age cycles occur when there is a continent at the South Pole.

Oooh, I’m looking forward to this. But I’ll look when I’m somewhere that it’s easier.

Thanks Renfield, and thanks DBrow for that link.
Vindicated at last!

Emilio Spedicato's idea (circa the 1990s) is that ice ages are caused by impacts on land, and ended by impacts on water; that seemed wrong immediately, but gave me a thwack on the forehead -- ice ages are caused by impacts on water, always, and they end due to the fact that the distance to the Sun doesn't change much, and basically everything thaws out. This explains the ice distribution, and permits ballparking the location of the originating impact (or impacts, in the case of doublet impacts).

Nice graphic. Notice how the past four glacial periods have been increasingly colder? The trend of the interglacials is decreasing average temperature. And the temperature trend of the last 2000 years has been downward. I don’t think we have a whole lot of time left until the next deep freeze.

Methinks the only thing saving us from a deep cooling now is ... “global warming”.
