Geologists tell us that the Earth is about 4.5 billion years old. During that time, there have been five Ice Ages totaling about 500 million years in duration. An Ice Age is when global temperatures are relatively cold, there are large ice sheets, alpine glaciers and the polar caps are covered with ice. Ice ages have existed for about 11 percent of the entire Earth’s history. It may even come as a surprise to some that we currently live in an Ice Age called the Quaternary Ice Age which began about 3 million years ago.
For the other 89 percent of Earth’s history, it has existed as what is called “greenhouse Earth” where there are no continental glaciers anywhere on Earth, no ice sheets and little, if any, ice on the polar caps.
With the understanding of just these two facts, one should be able to conclude that the normal state of the Earth would be “greenhouse Earth” with temperatures ranging from about 85 degrees F in the tropics to about 32 degrees F at the polar caps. That means no glaciers, no large ice sheets and little, if any, ice on the polar caps. The amazing thing to me, since my mind has been inundated with theories about “global warming” and “climate change,” is that this normal state of “greenhouse Earth” existed without the help of civilized human beings since we didn’t even exist.
What is it about human kind, then, that we insist that the current climate we are in is the ideal climate that must be maintained at all costs? What makes us think that we are so “God-like” that we are causing climate change? What makes us think we can stop climate change? And what makes us think that climate change is a bad thing?
From a practical point of view, the Earth’s reverting to the state it has existed in for 89 percent of its existence has some immediate benefits. Large tracts of land, from Siberia, across Canada and all of Alaska would become arable — suitable for growing crops — which means we would be able to feed more people at lower costs, (my grocery bill would go down), a whole continent, (Antarctica) would be open for development giving us room for more people, (or at least a place to relocate those people living on our current coastlands), and the use of fossil fuels for heating would go down, (along with my winter heating costs), something which environmentalists have been demanding for decades.
So climate change, which we did not start and cannot stop, I say, “bring it on.”
And that’s the long view.
