American West Heating Twice as Fast

317488203_967e4514e6_m.jpg Don't think climate change is going to affect you? Well, if you live in the American West, it already is. In fact the west is heating up faster than the rest of the world, reports the National Resources Defense Council. The average temperature rise in the drought-struck Colorado River basin is more than double global average—especially bad news for the 30 million people living in Denver, Albuquerque, Las Vegas, Phoenix, Los Angeles and San Diego, among the nation's fastest growing American cities and all dependent on the Colorado for water.

The Rocky Mountain Climate Organization analyzed temperature data from the National Oceanic and Atmospheric Administration for 11 western states and found the average temp in the Colorado River Basin, from Wyoming to Mexico, was 2.2 degrees Fahrenheit hotter than the historical average for the 20th Century, and more than twice the global rise of 1.0 degree. Throughout the West, the average temperature increased 1.7 degrees. "We are seeing signs of the economic impacts," says study author Stephen Saunders, including $2.7 billion in crop losses since 2000, commercial salmon losses, reduced hunting revenues, and shorter, less profitable ski seasons. The Colorado River Basin is in the throes of a record drought and climate scientists predict more and drier droughts in the future as hotter temperatures reduce the snowpack and increase evaporation. "We need strong leadership from western senators to pass America's Climate Security Act," said Spencer.

How about any leadership? You know, turning off the lights one hour a year ain't gonna work. In 2007 I was optimistic about Earth Hour. A year later, I'm like, is this all we're ever going to do?
