It's Earth Day, a time when Americans take a step back and look at the state of their world - and if you look at the numbers, it's a world that's losing its cool. We've had 28 straight years of warmer average temperatures, and July 2012 was the hottest month ever recorded in the continental US, with an average temp of 77.6F – 3.3 degrees above the 20th century average for July. Eleven of the twelve hottest years on record since 1880 were the most recent – 2001 to 2011.
