Paris: winners and losers

Pillow diplomacyWhat can I add to the millions of words in dozens of languages that have already been written by the thousands of journalists and commentators around the Paris Agreement? We now have a globally binding agreement that really looks like it could curtail the use of a fuel that has been central to our way of life for more than 150 years.

Of course, if we’d managed to actually make deep cuts in emissions 25 years ago, getting governments to limit warming to 1.5 degrees would have been an awful prospect – who would want that much warming.  When I started working on this, it might have been possible to have no warming at all.

And if industrialised countries had actually made deep cuts in emissions when they said they would,  would we even be having an argument about equity?  Hindsight is a wonderful thing, but let’s look forward here. What’s in this agreement?

Climate battle at NBR: Rodney’s rubbish versus Wiggs wisdom

New Zealand’s leading business media outfit — the National Business Review — has long dallied with climate denial, providing a platform for former ACT party leader Rodney Hide (amongst others) to push climate tosh. Last week Rodney used his regular opinion column to attack the government’s emissions policies (behind paywall) — fair enough, given that they are rubbish — but his rationale was that it was a waste of time because climate change wasn’t happening:

So what about the temperature record? Where is this being reported? Where is the headline? It’s the easiest question to ask, the best news to report and the only salient fact in an ocean of green wash and government propaganda.

And what’s that news? No global warming for nearly 20 years.

So far, so predictable… and so wrong. Here’s the latest news:

GISStemp20153

The last 12 months have been the hottest in the long term record. So was the year ending in February. With an El Niño event brewing in the Pacific, 2015 is on course to set a new record for hottest calendar year. 14 of the 15 hottest years have occurred this century. And that’s just if we look at surface temperatures. If we look where most of the heat is going — into the oceans — there’s no sign of any pause at all.

Rodney’s column attracted a comment from another NBR columnist, Lance Wiggs, a man with some real business chops and a respect for scientific evidence. That in turn sparked a battle of the columnists in this week’s NBR: Rodney’s rubbish, versus Wiggs’ wisdom.

NZ: pushing the world to go beyond 2 degrees

head-in-the-sandNew Zealand is coming under increasing scrutiny in Lima, not least because it’s our turn to be reviewed by the UNFCCC process.

Early next week our representatives will have to defend our position and our lack of action to 190 governments in our first “multilateral assessment.”

Already, there have been some tough questions, coming especially from the EU and China. New Zealand’s answered them, but will have to more to defend itself than these carefully fudged answers.

Our negotiators have been trying to promote our position around the meeting, including a botched attempt in a science discussion yesterday, when they were interrupted halfway through a blatant PR presentation. They were told to get back to the issue at hand (science, not promotion of a country’s so-called “efforts”), after a number of governments objected to our highjacking the agenda.

Record winter warmth in NZ: June 2014 breaks 140 year record

NZ7SSJune14

Hot off the press — or to be precise, Jim Salinger’s laptop: June 2014 was the warmest June in New Zealand since 1870, 2ºC above the 1971-2000 average, as measured by the long term “seven stations series” originally devised by Salinger and maintained by NIWA. On the larger 24 station series the month tied with 2003 at 2.1ºC above the 1971-2000 average. Many stations recorded warmest ever Junes, including Dunedin with 8.7ºC, +1.7°C above average, Invercargill with 7.8ºC (+2.2°C), Kaitaia (14.5, +1.7), Tauranga Aero (13.1, +2.4), Masterton Aero (9.8, +2.3), and Hokitika Aero (+10.4, +2.4). Jim points out that NZ warming is most clearly seen in the winter months (and expressed in the snow and ice record) but often escapes notice because a warm winter month is still “cool” compared with the seasons around it.

[Update 3/7: The Australian Bureau of Meteorology reports that the 12 months ending in June were the warmest July/June since records began (The Age. Jim Salinger tells me that in New Zealand July 13 to June 14 was the 3rd warmest in the long term record.]

WMO 2013 climate summary: laws of physics not negotiable, extremes to be expected on a warming planet

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 century1, 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.
