It’s been a long time since my last post: apologies for that. You may blame a bad cold, an urgent need for root canal work, the peak of the truffle season (and truffle tours for culinary heroes ), the start of pruning and political distractions for the drop off in activity here. Normal service should resume in the near future, but meanwhile here are a few of the things that have caught my eye over the last week or two. You may therefore consider this an open thread – and given what follows, somewhat more open than usual…
The political distraction, of course, has been the response to Nicky Hager’s book, Dirty Politics. I haven’t yet read the book — it’s queued up on the iPad — but as everyone now knows, it concerns the sordid activities of right-wing attack blogger Cameron Slater, and in particular his close ties with senior government politicians. Slater has a long record of climate denial — often lifting material from µWatts or the Daily Mail to support his ignorant bluster — but the revelation that he published paid material for PR companies masquerading as his own opinion begs a question: was there a similar motivation for his climate denial posts?

The World Meteorological Organisation’s (WMO) state of the climate report for 2013 was released on Sunday (pdf), and provides a very useful overview of last year’s weather and climate events. It confirms that 2013 was the 6th warmest year in the long term record (tied with 2007), that 13 of the 14 warmest years in that record have occurred this century, and that the litany of extreme weather events that struck the planet is in line with what would be expected on a warming planet.
WMO Secretary-General Michel Jarraud said:
There is no standstill in global warming. The warming of our oceans has accelerated, and at lower depths. More than 90 percent of the excess energy trapped by greenhouse gases is stored in the oceans. Levels of these greenhouse gases are at record levels, meaning that our atmosphere and oceans will continue to warm for centuries to come. The laws of physics are non-negotiable.
On extremes, Jarraud was equally direct:
…many of the extreme events of 2013 were consistent with what we would expect as a result of human-induced climate change. We saw heavier precipitation, more intense heat, and more damage from storm surges and coastal flooding as a result of sea level rise – as Typhoon Haiyan so tragically demonstrated in the Philippines.

Warsaw has seen a deluge of important climate-related information released — so much that it’s been difficult to keep up — but still not enough to steel negotiators to reach an equitable arrangement that gives us all a chance at a reasonable future climate. And at the same time, the planet has been sending signals that it’s not happy. The Pine Island glacier has finally calved the giant iceberg that first started to shown signs of cracking away from the ice stream a couple of years ago. Iceberg B-31 has been described as being the size of Singapore (about 700 km2), but isn’t likely to move far from Pine Island Bay in the near future. NASA Earth Observatory coverage here and here; see also Telegraph (UK) and Antarctic Sun.
The Global Carbon Project announced earlier this week that greenhouse gas emissions are projected to reach the highest level in human history this year — 36 billion tonnes. There are some encouraging signs that the rate of growth may be slowing, but nowhere near enough to enable the planet to avoid hitting a two degree rise in the first half of this century. There’s an excellent visualisation of national emissions at the Global Carbon Atlas (and at the Guardian). See also The Age, Think Progress.

Last week the UK Meteorological Office issued its annual forecast for the global average temperature for the year ahead. They’re expecting a warm year, but very few people seemed to notice just how hot. Here’s what the press release had to say:
2013 is expected to be between 0.43 °C and 0.71 °C warmer than the long-term (1961-1990) global average of 14.0 °C, with a best estimate of around 0.57 °C, according to the Met Office annual global temperature forecast.
Taking into account the range of uncertainty in the forecast and observations, it is very likely that 2013 will be one of the warmest ten years in the record which goes back to 1850, and it is likely to be warmer than 2012.
Most press coverage ran with the “one of the warmest years” line, a simple elaboration of the press release, but few noticed that the Met Office were actually predicting a new global temperature record — perhaps because the Met Office wasn’t exactly trumpeting the fact from the rooftops. Admirable caution, you might say.

Shelob/Maman lurks over Doha delegates.
Every time I walk into a press conference it seems there’s more ‘cheery’ news. Yesterday it was UNEP releasing a science report on melting permafrost. Scary stuff. So scary that The Age in Melbourne gave it most of the front page and even some on the back page. (Meanwhile the NZ media was all about Hobbits).
According to the report, if the permafrost keeps melting like it has been, the gases it releases will make up 39% of emissions in 2100 (a combination of release of trapped methane and C02 from decomposing matter).
Then today it was the World Meteorological Organisation’s State of the Climate provisional report. 2012 was no exception to the trend of rising temperatures. “Global warming isn’t a future threat: it’s happening now,” intoned the official, pointing to this year’s Arctic melt as evidence.
These organisations save this stuff up for the climate talks, but sometimes one has to wonder why. I heard a UN official telling a newbie to the process that none of this would have any effect on the delegates at the talks. “They’re in a bubble – they’re totally immune to this stuff,” he said. And he’s right.
Some of these officials have been coming to the climate talks for more than 20 years and they don’t see anything beyond their negotiating tables. What might have an impact would be if they get home and their kids, having seen the permafrost or WMO stories, start giving them hell about it. I hope they do.
