Tom Rippeth, Bangor University Arctic sea ice today (white) is covering a much smaller area than in 1980-2010 (orange line). National Snow and Ice Data Center, University of Colorado, Boulder, CC BY-SA Each September, scientists like me look out for the point when the Arctic’s meagre summer fizzles out and sea ice begins to grow once more. This point … Read More

A classic case of WACCy weather in the northern hemisphere, seen here in a map from the excellent Climate Reanalyzer site, prompts me to discuss the 2013 global temperature numbers, the El Niño-Southern Oscillation, and what sea ice loss is doing to northern hemisphere weather patterns in my post at The Daily Blog this week. […] … Read More

The dramatic loss of summer sea ice in the Arctic has prompted a lot of research interest in the way that this is affecting weather patterns around the northern hemisphere. The latest contribution is Influence of Arctic sea ice on European summer precipitation, by Dr James Screen of the University of Exeter [PhysOrg]. In this […] … Read More

We’re running a bit late with this one: recorded last week before the big wind left Gareth powerless for six days (a bit like Glenn’s PC), John Cook ruminates on the result of the Australian election, the boys marvel at the Mail’s myth making about Arctic sea ice, and look forward to the release of […] … Read More

Stephen Sackur took the BBC’s HARDtalk programme on the road in Alaska in a climate change episode screened a few days ago. It was the kind of aware and intelligent journalism one hopes to see on the topic, and deserves plaudits. Not that it exceeded what we have a right to expect from major mainstream […] … Read More

Reading this press release about a new paper in Palaeogeography, Palaeoclimatology, Palaeoecology spoiled my day. It might not be obvious to a casual reader just glancing through the morning news — but a couple of paragraphs leapt out at me: Atmospheric carbon dioxide concentrations recently reached 400 parts per million for the first time since […] … Read More

Looking down on the North Pole from satellite, NASA’s Arctic mosaic image for July 14 shows an unusually cloud-free view of the sea ice covering the Arctic Ocean. Click on the image to see the bigger original, and to zoom in on interesting regions. So far this year the sea ice melt has lagged behind […] … Read More

It’s certainly hot in the southwestern USA at the moment — a dome of heat has established itself under a persistent high pressure ridge, and temperatures are pushing up towards all-time highs. Wildfires are running out of control. One caused the tragic death of 19 firefighters at Yarnell Hill in Arizona yesterday. One more extreme […] … Read More

Kicking off the afternoon sessions on the first day of this year’s NZ CCC conference, Professor Barry Smit of the University of Guelph in Canada launched his keynote — titled From theory to practice, from impacts to adaptation (abstract) — with a rousing climate version of Let It Be. I caught up with him during [...] … Read More

So Cook et al1 confirms that there really is a consensus in climate science: 97% of the peer-reviewed literature over the last 20 years supports the fact that humans are responsible for the warming. It’s a solid result, confirming the earlier work of Oreskes and others, but its importance lies in the fact that public [...] … Read More
