Here’s the final interview I recorded at last week’s NZ Climate Change Conference in Palmerston North: VUW’s Dr Jim Renwick ((Apologies to Jim for inadvertently using the British pronunciation of his surname in the introduction. I’m told that my usage is a reliable indicator of a migrant from the UK… )) talking about the complex relationship between the southern annular mode — a north-south movement of the westerly winds that blow around Antarctica — sea ice growth and the ozone hole. It’s interesting stuff, not least because SAM has a significant impact on NZ weather and climate, and how it might change in the future is a very big factor in projecting southern hemisphere climates in a warmer world. The abstract of his conference presentation, Antarctic sea ice, the SAM, and the future of the ozone hole, is here.
