LESS GAS

Talk about putting your wealth where your words are: Al Gore is funding a multi-million dollar advocacy campaign called We Can Solve It, calling for the US to reduce greenhouse-gas emissions: "Gore Launches a Campaign to Cut U.S. Greenhouse Gas." Given that the topic is a global one and not just an American one, it will be key to get other countries, notably fast-developing China and India, on board. Although it is likely that aggressive and thoughtful action by the world's most powerful nation is what it will take to get this thing really cooking on a planet-wide scale. And by the way, wherever you stand on Gore's various political positions, kudos to him for being so engaged and so influential after his White House years.
