A column in today’s Times by Timothy Egan noted that the average annual temperature in Las Vegas has risen more than four degrees since 1970. Four degrees might not seem like much, but it will change whole ecosystems. Lake Mead, the body of water behind Hoover Dam, has fallen by 100 feet. The Southwest is in the middle of one of the worst droughts in 500 years.
Amazingly, there are still many people who think global warming is a hoax. I’ve seen their letters in the Morning Call and the Times News. Oh, and one was recently President of the United States.
