Global Warming?

Coworker tells a school teacher customer that the horrible, cold weather we've been having makes him doubt global warming. She then lectures him on how cold weather is proof of global warming, since that means the glaciers are melting.

Now, I'm not the smartest guy on the planet, but ice has to remain at 32 degrees to be ice. You raise the temperature to 33 to melt it, that's a rise in temperature. As the water melts, the temperature is not going to decrease because there's more cold water around. The water's going to be 33 degrees, and it's going to have to stay 33 degrees to remain water. If anything, the temperature may go up.

Anyway, I explained to Dom that mankind accounts for 15% of the greenhouse gasses that contribute to global warming. Mother Gaia *snicker* accounts for the other 85%. The US accounts for roughly 5% total. So, knowing that manmade global warming is bunkum, that nothing we do is going to have any measureable impact on global warming, and that unless we turn off all electricity tomorrow and go back into the stoneage we're not going to manage more than a .5% total reduction (and that's being generous), does it make any sense to write all this bullcrap legislation and outlaw good lightbulbs and hi-flow toilets? Resoundingly, intelligently, NO.
