First, the "glacial period" bullshit. The truth that Greenland froze while North America thawed proves the idiocy of the Co2 Fraud and its taxpayer funded "skeptic bull" solar cycle is wrong. The planet does not warm and cool as a whole. Climate change is about continent specific ice ages. Right now on earth
South Pole
Antarctica is within 600 miles of a pole. Any evidence of a continent specific ice age on Antarctica today??? It just has 8 million cubic miles of ice on it, 90% of Earth ice...
North Pole
Northern tip of Greenland is in the 600 mile "switch" radius. What's up with Greenland, any ice there???
Ellesmere Island in Northern Canada is also there with 0.3% of Earth ice....
Let's see if you notice any difference???
Right there, it takes an IQ of 40 to figure it out. Two polar oceans, Earth has no ice. Two polar continents, Earth has 80%++ more ice and oceans are lower, atmosphere thinner etc...
What matters is where land is relative to the poles....
And land moves...
