I'm pretty sure that the global warming trend is a long term thing, not a representative of temporary annual weather patterns. It is best measured by net sea ice after annual freezes and thaws. Polar ice is a natural thermometer which has nothing to do with politics. Unfortunately the issue has been politicized. Again, if this trend continues it is something that will probably have dire effects over a scale of 10's of thousands of years. I don't think it is a bad idea to become aware of our personal impact and make a gradual attempt to lean toward clean energy as technology improves. To put it in LAY MAN's terms...The angle of the dangle is equal to the heat of the meat, divided by the mass of the ass, with a coefficient of 7, on Tuesday afternoons between 1 and 3, ONLY...EST!
