The Climate Show #25: Box on ice (a polar special)

As the northern hemisphere starts to warm (rather rapidly in the USA), climate watchers’ thoughts turn to melting ice, and to tell us what happened last year and what might be in store this summer, Glenn and Gareth welcome back Greenland expert Jason Box from the Byrd Polar research Centre at Ohio State University. It’s a wide ranging and fascinating discussion, not to be missed. John Cook looks at the differences between sea ice in the Arctic and Antarctic, and we have news coverage of the new HadCRUT4 global temperature series, summertime in winter in the USA, worrying news about sea level from the Pliocene, a new report on climate change in the Pacific, and new developments in solar power and biofuels.

Shapes of things (2012 and all that)

‘Tis the silly season, time for journalists with little real news to report to reflect on the year past and make predictions for the year to come. I don’t normally play that game because there are too many interesting things to write about on the climate beat, but this year I’m going to make an exception. Glenn “Climate Show” Williams persuaded me to have a chat with him on his summer Radio Live show — and yes, we did cover the last year, and the prospects for 2012. The audio’s available to stream for the next week from the Radio Live site (select Dec 28th, then the 1-15pm segment — my bit starts after about 5 minutes). You may regard this post as an expanded version of my comments there (and a bit of recap on the last Climate Show of the year).

So: 2011 was the year of extremes, beyond any shadow of doubt. Wherever you looked around the world, there were record-breaking floods, heatwaves and hugely damaging extreme weather events. The USA alone had 14 separate extreme weather events with billion dollar plus damage bills (NOAA puts it at 12 with 2 more to finalise, the World Meteorological Organisation plumps for 14). The year broke no records for global average temperature — 2011 will probably end up as the 10th or 11th warmest year in the long term record — but it will be the warmest ever La Niña year. Here’s a WMO graph to illustrate the point:
