Dear Climate Solutions Thinker, I had the opportunity to speak with Dr. R. K. Pachauri this past week when he visited Columbia University.
I asked him about the state of the climate, his take on James Hansen's research suggesting that 350 ppm is the safe upper limit of atmospheric carbon dioxide (we're at 387 ppm now), and if he knew about "biochar."
