Back on the farm we ten year-olds absorbed the wisdom of our elders. One gem was: “It’s a great life if you don’t weaken.” There was also, “Just between you, me, and the gatepost.”
There were many others, too politically incorrect to repeat here, to tease the imaginations of naïve young parrots. But one that was well within the observational experience of a ten-year-old farm boy was, “A dog doesn’t (defecate) on its own doorstep.”
It’s on this premise alone that I support the efforts of those who are crying alarm about global warming. There is no question but that for reasons of need and greed the human race has been polluting our environment at an ever-increasing rate and intensity since the industrial revolution kicked in about 250 years ago.
But world geological history cautions us not to panic. For millions of years before we trotted forth with our industrial obsessions our planet had known global warming and colding in the extreme.

it ice age — was the

Taking the earth as a whole the deep freeze involved 30 million cubic kilometres of ice that required freezing the equivalent of the top 70 metres of all the world’s oceans. You can imagine what that did to shorelines everywhere.

The point is that long before we came along to contribute to global warming and colding, the earth, one might say, had a mind of its own. And I suggest that it still does.
The hue and cry about burning fossil fuels and creating a blanket in the atmosphere that will warm us to distraction should be tempered by the realization that there is a finite amount of coal, oil, and natural gas that we can dig or pump up.

The problem of pollution will have ended all by itself as if our planet was to say, “That’s it, that’s all. Now go and find some other way to amuse yourselves.”
Some scientists contend that the cycle of cold and heat is a pattern of our planet’s behaviour that has nothing to do with our relatively miniscule, puny machinations.
They argue that a warmer-than-usual period always precedes the return of an ice age.
One might think then that the most cautious among us, aside from cheering on the environmentalists who warn of pollution and global warming, would prepare for either hot or cold or both one after the other.
In other words, hope for the best while preparing for the worst.
