Young People's Burden

NPR's Tom Ashbrook interviewed climate scientist James Hansen recently about his co-authored paper "Young People's Burden," which asserts that we must not merely reduce our carbon emissions but achieve "negative CO2." If we don't, said Hansen, the eventual cost of mitigating the impact of catastrophic climate change will range upwards of $535-trillion. Ashbrook asked if this "totally mind-boggling number" was related to the climate-related lawsuit Hansen's granddaughter and others have filed against the U.S. Government. Indeed, replied Hansen, the study provides "some of the science to support that lawsuit." Leveraging economic doom against ecological disaster—that's good climate science.
