Five Stars. Must watch video.

John Holdren is one of the only scientists in the world to speak of the stark reality of climate change.

(The other most ethical, most outspoken scientist being James Hansen) His position is based on facts known to all scientists - yet the scientific community continues to ignore his recommendations.

Here he is speaking at the Kennedy School of Government on November 6, 2007.
Dr. Holdren states the disruption and its impacts have grown more widely than anyone ever expected a few years ago.
He states: the world is already experiencing "dangerous anthropogenic interference in the climate system."

The question now is whether we can avoid catastrophic interference.

A video of Dr. Holdren’s talk, and his slides, is posted in the John F.
Kennedy Jr. Forum archive.
