FUNDAMENTAL TRUTH #6: “No one bitched about global warming when it ended the ice ages.” -Old Pithy

Posted by PITHOCRATES - March 23rd, 2010

ICE AGES AND glacial movement are complicated.  We know that glaciers exist.  And that they move.  They do so today. 

Scientific study has determined that we have had at least 5 major ice ages.  During these periods the glaciers moved out from the north and south poles.  During the last ice age, they covered many of today’s populated areas.  Most of Canada, Seattle, Chicago, New York, most of Great Britain, northern Europe and Moscow were all under ice at one time.  The ice moved closer to the equator during previous ice ages.  Ice may have covered the entire earth at one time.  Or come close to it.

During the cooling and warming of the earth, glaciers traveled great distances.  Close to 2,000 miles in North America during the last ice age.  And this great movement is cyclical.  It’s happened 5 times already.  And it will most probably happen again.

In front of the glaciers is permafrost (permanently frozen soil).   As the glaciers and permafrost moved forward, life moved away from the cold.  Species died out (the woolly mammoth, the saber-toothed tiger and Neanderthal man, for example).  The advancing ice pushed life towards each other and into conflict as they fought for the increasingly limited food supply.  When the cold receded, life followed, the newly warmed lands able to support life again.

There are various theories about what caused the ice ages and glacial movement.  One thing for certain, though, cold kills.  Warmth, on the other hand, allows life.  Warmth is good.

THE KEY TO civilization is the food supply.  Only when there was a surplus of food did civilization begin.  The surplus of food allowed the division of labor.  Farmers farmed.  Tool makers made tools.  Leaders led.  And soldiers protected the civilization.  None of this happens without a surplus of food.  If you didn’t have to grow food, you could do something else.  And people did.  And they created modern civilization as we know it.

Farming was the quantum leap forward in producing a food surplus.  The first civilizations grew grain and cereal crops in the fertile soil of river valleys.  An arc from the Nile valley up through the eastern Mediterranean, through Lebanon, Syria, and down the fertile river valleys of the Euphrates and Tigris valleys forms the ‘fertile crescent’.   Anchoring the crescent at each end are history’s first civilizations.  Sumer (#1) and Egypt (#2).

Fertile soil and a warm growing season allowed this.  Again, warmth is good.

THE EARTH HAS cooled and warmed.  There are many theories why.  No one can be certain.  But what we can be certain of is that warmth is good.  Cold is bad.  Ice ages are cyclical.  And the glaciers receded further in periods when there was not a single man-made greenhouse gas in the atmosphere.

We’re probably 50,000 years or so before the glaciers come back and cover civilizations everywhere.  If man-made greenhouse gases warm the world greater than the natural cooling mechanisms advance the ice, perhaps life will continue.  None of us alive today, though, will have to worry about that.  When the ice comes again, future generations will face that horror.  Until then, let there be warmth.  And life.

CHICKEN LITTLE SAID the sky was falling and there was panic.  And so it is with global warming.  Well, the sky wasn’t falling on Chicken Little.  And it is unlikely that man is causing global warming.  Global warming existed before man created greenhouse gases.  The ‘scientists’ who say the world as we know it will end unless action is taken are more politician than scientist.  Ever wonder why the solution to global warming is the growth of government?  To me, that sounds something like what a politician would say, not a scientist.
