Does general relativity influence climate (vs Newtonian mechanics)

In short: No. Unless multi-million timescales are considered. The reason we keep teaching Newtonian mechanics, is because it is a VERY accurate approximation of a more general theory (general ...

Are we entering a new Ice Age according to Milankovitch cycles?

It thus seems reasonable to say we are entering another Ice Age according to Milankovitch cycles. Some of the Milankovitch conditions would appear to make the Earth ripe for a new glacial epoch ...

Is 2,000 years from now a credible figure for return to glaciation?

It's a little dated and brief, but it's a cool article and I believe it's overall sound in it's predictions and arguments presented. On the overall point, the author isn't predicting an ice age in ...

Does general relativity influence climate (vs Newtonian mechanics)

I don't see this point made, so I'll just add it. In very high gravitation situations orbital energy can be lost to "relativity" or more specifically, gravity waves. The primary relativistic effect ...

Does general relativity influence climate (vs Newtonian mechanics)

The latest positions that I am aware of say yes, but not in any useful way. From what I have read, the current prevailing opinion is that the weather of Earth is a chaotic system. Chaotic systems ...

Effect of eccentricity and axial precession on glaciation/deglaciation

Does high eccentricity in combination with perihelion Northern Hemisphere summers (and hence aphelion winters) lead to deglaciation or glaciation? Paradoxically, it's the other way around, at least ...

Why were the Interglacial periods in the early Pleistocene spaced about one million years apart, but recent ones only 100,000 years apart?

It was a transition from a 41000 year cycle to a 100000 year cycle that happened about a million years ago (the Mid-Pleistocene Transition), not from a 1000000 year cycle to a 100000 year cycle. There ...
