Tilt! A word associated with pinball games (if anyone remembers what those are) is now associated with the warming and cooling of the planet.
The idea that slight shifts in Earth’s axis might have been enough to trigger the ice ages is a century old.
But a Harvard earth sciences Professor Peter Huybers has finally proved it, using computer models to test competing ideas – and finding that earth’s tilting axis is the only one that works.
So, per this, it’s not that nasty old anthropogenic (man-made) CO2 that certain warmers have been blithering about for decades, it’s the variation of the tilt of the Earth’s axis, something I remember hearing about in grade school about 50 years ago, in pre-Goracle times when kids were taught actual science and didn’t major in Greentard Brainwashing 101.
Two ‘cycles’ in the way Earth’s axis spins have an effect on the cycle – one lasting 10,000 years and one lasting roughly 40,000 years.
When they align correctly, ice melts. At the other extreme, glaciers advance.
‘And at least now we know with greater than 99 percent confidence that shifts in earth’s axis are among the factors that contribute to deglaciation.’
OK. We’re waiting for certain people out there we all know and ‘love’ to capitulate and say ‘oops!’, but we won’t hold our breath.
