Same series, episode named "Sahara Info" discusses the emerging evidence that the Sahara goes through 20,000 yr cycles of fertile/desert/fertile. Seems the earths wobble causes the tilt of the axis to shift on a regular basis is the working hypothesis. Cycle has been confirmed going back 3 million years. Basically earth rocks! Naturally the axis shift does affect the whole planet. So much for man made global warming.

Yes.

And our 150 years of tracking temperatures isn't even an eyeblink to the scope of geologic time.

Of course the earth is getting warmer -- we're still emerging from the Younger Dryas, which was the last gasp of the Wisconsin glaciation. Most interglacial periods feature ice-free poles and there's no reason not to expect the same this time.

This process being a three-steps-forward, two-steps-back thing, we have historical evidence that civilization thrives during the warmer times so this natural process is actually a good thing.

Solar is the power of the future and the power of the past. What solar isn’t, is the power of the present. That’s because using solar power to generate electricity is expensive. Still. And that’s not going to change anytime soon, no matter how many political fundraisers are held by solar advocates.

According to Bloomberg, recent price decreases in solar equipment have driven costs from about 25 cents per kwh to 17 cents per kwh for photovoltaic (PV) powered solar energy, the least expensive form of solar power deployable at scale. But that’s a far cry from the average retail price...
