What a superb presentation! A real scientist outlining a real scientific description of important aspects of global climate change, and also outlining sensible recommendations for how to address these changes.

Even though the information is disturbingly grim, the willingness to look at reality and then to respond intelligently is encouraging.

We need the education element of the response badly.

Science has been misconstrued as "research to make new and better toys" for too long. People need to understand that science -- and our lives -- will be about conserving enough habitat for us to survive for a few more years or decades, and maybe beyond if we get lucky and blessed along the way.
