Well over 10,000-years ago (give or take a century or two either way), the Northern Polar Ice Cap crept its way to North America. Massive ice sheets would find themselves eventually in what would become both Canada and the Unites States.
At the southern-most boundaries, the ice went as far south as the Washington-Oregon border, central Iowa, northern Ohio, finally stopping in the northernmost area in what is now New Jersey.
But wait, there’s more.
On the other side of the planet, glaciers existed as far south as the south of Spain, central Italy, and the Caucaus Mountains.
So, what’s the purpose of this history lesson of the last major ice age?
Real simple – centuries upon centuries ago, glacial ice up to 800 feet thick, all managed to recede to their present boundary all without billions of human beings, factories all across the globe, or even cow farts.
Golly gee, one would think that warming and cooling is the natural rhythm of the planet, huh?
