Time to get busy!
Global warming, which means more extreme weather and rising sea levels, is here according to this article: No Stopping Global Warming, Studies Predict. So what can one person do? Well, for a start you can get as economical as possible in your energy use. And you can get rid of that gas-guzzler and buy a hybrid. That's what I did last year and I'm getting 45 mpg. I bought the Honda Civic Hybrid and it's a great car. Honda now has the larger Honda Accord Hybrid available too.
So do whatever you can. If enough people act then we can do something about it.
