A busy news week sees Glenn and Gareth discussing volcanoes in Chile and Africa, busy pumping ash into the atmosphere and disrupting flights in South America, Australia, New Zealand and the Middle East, an extreme spring in the USA, drought in Europe and a warm autumn in NZ, a new UN report on black carbon and how a reduction could cut future warming, Aussie scientists fighting back against climate denial, and forecasts for the summer ice minimum in the Arctic. John Cook from Skeptical Science deals with their new series on John Christy's climate crocks, and introduces a great new graphic front end for the SkS climate literature database, plus we cover price reductions on solar panels, LEDs on streetlights in San Francisco and MIT's Cambridge crude. http://www.theclimateshow.com
