time's a-wastin'

So it was 20 years ago today that NASA scientist Jim Hansen gave Congress the warning that climate change/global warming was real and was a threat. And now he's testifying before Congress again to say it is still real, is even more a threat, and is already here to a small but growing degree.

It is thoroughly depressing that so little has been done over the past 20 years. It is simply scary to consider the ramifications for the planet and the future of human civilization if similarly little is done over the next 20 years.
