The subject is heating up.  Notice how the media and the cognoscenti, whoever they are (but they are superior to us, you know), just take global warming and human causation of the phenomenon for granted.  For the rest of us benighted simpletons, we need just fork over our taxes, give up cars, turn our heaters and air conditioners off, and live with reduced incomes as corporations and industries are extorted in the holy cause of the 21st century.

As a simpleton, however, I have a few simple questions:  1)  Why was there a second ice age proclaimed just 30 years ago and now we’re convinced of global warming?  2)  Why was it warmer in the Middle Ages than now, but that was okay since there was no industry to cause it, etc.?  3)  Why is Mars heating up at the same level as our planet when, insofar as we know, there are no human activities on that orb?

Simpletons want to know the answers.
