Climate Change, the Vatican and Poverty

Governor Jerry Brown is at the Vatican, where the Pope is hosting a conference on climate change. One warning siren about climate change rose above the rest this week, from prominent climate scientist James Hansen — the guy who pretty much put climate change on the map back in 1988. In a new report, Hansen says that in less than 50 years, we'll witness a rise in sea level of at least 10 feet. Coastal cities like New York will be rendered uninhabitable in only a few decades.
