"Dear Mr. [Al] Gore: I am a former astronaut, Cornell professor, physics faculty member at Princeton University and visiting faculty member in technology assessment at the University of California, Berkeley School of Law, I was Mo Udall’s energy advisor and speechwriter during his 1975 Presidential campaign, author, AAAS Fellow, World Innovation Foundation Fellow, NASA group achievement award recipient, and founder of the New Energy Movement.You have asked the public to address the important question, “How can we reverse global climate change?” I agree that taking on that task is critical for our collective survival. You have also stated that we must freeze and drastically reduce our carbon emissions. I agree.The most promising answer to your question is surprisingly simple and can be summed up in two words: new energy. My experience finds that serious discussion of new energy is still politically incorrect in mainstream circles, which is appalling. Delays in implementing life-saving innovation will be at our collective risk and peril. The urgency for action in these times is unprecedented in the human journey. Quantum leaps in energy innovation, which some of us in the scientific community are aware of, can provide the needed solution, hopefully in time to avert global disaster."
