Man, it's hot out there. How hot is it? Don't worry, I'm not going to talk about climate change. I'm just trotting out some ideas for a Bob Hope-style comedy routine. And climate change would've probably been too edgy for Hope, anyway. So how hot is it? So hot that trees can't decide what season it is. Okay, needs some work. But it's true. CNN has this video about how the heat has confused the hell out of trees in the South: After it gets too hot, see, the trees redirect resources to only its most vital parts, conserving water and energy by redirecting them to the trunk. The trees' leaves change colors, wither, and fall off -- months ahead of schedule -- spurred by the harsh temperatures.
And regions around the world are experiencing those harsh temperatures, not just Little Rock, Arkansas. Russia is having one of its worst heat waves in recorded history, 9 nations have shattered temperature records this summer, and 8 others have tied theirs. 2010 is on track to be the hottest year in the temperature record, and the January-June period has already been confirmed to be the hottest ever.
Which means we'll soon have a lot more to worry about than trees changing colors.
