The Climate Show #12: twisters, Olaf on ozone, and Google in the sun

by Gareth on May 5, 2011

Ozone is the centrepiece of our show this week, with Dr Olaf Morgenstern of NIWA’s Central Otago atmospheric science lab (celebrating its 50th birthday at the moment) explaining the ins and outs of the ozone holes north and south, and their impacts on the climate system. Plus tornadoes, heatwaves, UN negotiations at an impasse, more melting in the Arctic, airships, see-through solar cells and Google’s solar towers. No John Cook this time — he’s been too busy launching his book (good luck with that John!).
