The Correct Temperature

There is an interesting recent article in The Freeman arguing that it makes sense, from an economic standpoint, to stop worrying about “climate change” and simply create more wealth.  It is worth reading.

But as I listen to certain elements in our culture engage in hand-wringing, preaching, exhorting, and condemning people, especially people in the U.S., on the urgent need to do something about “climate change” I have a nagging question that no one seems to bother answering.  I’ll come to that question in a moment.

In an article previously online (2009) at NOVA online, Kirk A. Maasch writes:

During the past billion years, the Earth's climate has fluctuated between warm periods - sometimes even completely ice-free - and cold periods, when glaciers scoured the continents. The cold periods - or ice ages - are times when the entire Earth experiences notably colder climatic conditions. During an ice age, the polar regions are cold, there are large differences in temperature from the equator to the pole, and large, continental-size glaciers can cover enormous regions of the earth.

In a related article, this same author says:

During the present ice age, glaciers have advanced and retreated over 20 times, often blanketing North America with ice. Our climate today is actually a warm interval between these many periods of glaciation. The most recent period of glaciation, which many people think of as the "Ice Age," was at its height approximately 20,000 years ago.

That NOVA is certainly not in the camp of those some would call climate “deniers” should be conceded by all.  But even this bit of information from outside the debate about “climate change” leads to the unavoidable conclusion that the earth’s thermostat is always changing.

This is not difficult information to discover.  So why is our societal din about climate change continuing?  Why have so many ordinary people been convinced to feel guilty about turning on a light for fear of creating some carbon dioxide?  Why does everyone keep harping about “carbon footprints”?  I have my suspicions about this, but that is not the point here.

The point is to finally ask my question, the one no seems to ask, let alone answer, in all this hubbub.  Here it is:  What is the “correct” temperature for planet earth?  And if you think you know what that is, tell us how you know this.

Earth cannot be too warm or too cool unless we know what the correct temperature is.  When politicians yap on and on about the need to do something about “climate change” because the earth is getting warmer, they owe us an explanation as to how they know what temperature the earth ought to be.  As Maasch points out, earth’s temperature has varied greatly in the past, both far above and far below what it is now.  Which of these many temperatures was “correct”?

And if you don’t know an answer to that question, an answer for which you can offer substantial proof, why are you still flapping your lips about the dangers of global warming?
