Global warming and the future of New Zealand

From Cambridge University: the director of the Scott Polar Research Centre, Prof Julian Dowdeswell talks about his job. He has to visit Greenland and Antarctica to measure glaciers, so there are lots of pretty pictures to watch. Not a bad job, even if the implications of what he’s finding (Greenland outlet glaciers doubling in speed) are worrying…

The Climate Show returns with a packed show, featuring one of the world’s best known climate scientists, NZ-born, Colorado-based Dr Kevin Trenberth — star of the Climategate “where’s the missing heat” emails. He’s been in New Zealand to visit family (experiencing the Christchurch quake in the process) and to attend a conference, and his comments on the state of our understanding of climate change should not be missed. John Cook of Skeptical Science returns with his new short urls and an explanation of why declines have never been hidden, and Gareth and Glenn muse on Arnie “Governator” Schwarzenegger riding to the rescue of climate science, cryospheric forcing and carbon cycle feedbacks from melting permafrost, and a new paper that suggests that current policies are pointing us towards extremely dangerous climate change. All that and hyperbranched aminosilica too…

A very wide ranging Climate Show this week, with Dr Philip Boyd of NIWA and Otago University explaining why fertilising the oceans to soak up more carbon is not likely to be our “get out of jail free” card, John Cook of Skeptical Science introducing the new Monckton Myths section of the site, plus interesting new papers on Atlantic warming adding to the Arctic’s problems, an accurate prediction of last year’s Pakistan flooding, and the coolest 1970s Datsun on the planet.

Climate talks heat up in Mexico, snow blankets Britain and much of Europe, and The Climate Show is at the heart of the action. Glenn and Gareth set the scene for COP16 in Cancun and then interview Oxfam NZ’s Barry Coates at the conference to find out how things are shaping up. Gareth explores the link between Arctic climate change and cold winter weather in Western Europe, John Cook debunks that favourite sceptic myth — that the world’s cooling — and we look at the potential for nuclear power to provide part of the solution to decarbonising the power economy.

Atmospheric methane levels continued to increase in 2009, the World Meteorological Organisation’s annual Greenhouse Gas Bulletin (summary PDF) confirmed this week. Methane averaged 1803 ppb over the year, up 5 ppb on 2008, and now contributes 18.1% of the radiative forcing caused by current greenhouse gas levels. The Bulletin suggests that “likely causes were above average wetland methane emissions due to exceptionally warm temperatures at high northern latitudes in 2007 and heavy precipitation in tropical wetlands in 2007 and 2008. However, it cautions that the reasons for the recent increases are not yet fully understood.”
A hint that the rise might be continuing this year is contained in this rather striking graph of methane levels recorded recently at the Mt Zeppelin recording station (a misty mountain?) in Ny Ã…lesund, Svalbard…
