The penultimate Cosmos episode was about carbon dioxide and human caused global warming. As usual, one could quibble about the way Neil deGrasse Tyson presents some points, but overall, I found it very good. I found the early history of solar power particularly interesting.
It's clear today that we could replace a great deal of our energy use with solar power in the next several decades if we could summon the will to do so. What is required is mostly political will, especially the political will to face down the hydrocarbon lobbies and their dim-witted accomplices. I believe that the best way to do this probably a combination of carbon taxes and solar energy subsidies.
