Dead rats and circumcision

IMG_3372 - Version 2Saturday afternoon in Lima.

On the good side, the one place selling good coffee is still open (the proper machines, rather than the horrible little Nescafe machines that the locals call ‘no es café.”) And I’ve managed to eke out my stack of kiwi Dark Ghana chocolate, saving the last big block for today.

On the not so good side, there’s rumours of the meeting reconvening from anywhere from 6pm to 9pm this evening. Goodness knows when it will end. Conversation turns to whether this will beat the record of Durban, which ended at 6.30 am on the Sunday morning.

Being a bit of a COP veteran, I left the centre at 8.30 last night, got dinner and a good night’s sleep, coming back for 10 am this morning to see a lot of bleary-eyed people who’d been up all night to witness a complete lack of agreement. Continue reading “Dead rats and circumcision”

Is earth’s temperature about to soar? (No pause, no hiatus, only warming)

This is a guest post by the statistician who blogs as Tamino, cross-posted from his Open Mind blog with his permission. It’s important reading…

A recent blog post on RealClimate by Stefan Rahmstorf shows that when it comes to recent claims of a “pause” or “hiatus,” or even a slowdown in global surface temperature, there just isn’t any reliable evidence to back up those claims.

Yet for years one of the favourite claims of those who deny the danger of global warming has been “No global warming since [insert start time here] !!!” They base the statement on the observed data of earth’s surface temperature or its atmospheric temperature. Then they claim that such a “pause” or “hiatus” in temperature increase disproves, in one fell swoop, everything about man-made climate change.

They seem a bit worried lately because it is very likely that the data from NOAA (National Oceanic and Atmospheric Administration) will record this year as the hottest on record; we won’t know, of course, until 2014 is complete. A single year, even if the hottest on record, has only a little to do with the validity of such claims, but a lot to do with how hard it is to sell the idea. Perhaps they dread the prospect that if the most recent year is the hottest on record — in any data set — it will put a damper on their claims of a “pause” in global warming. If they can’t claim that any more, it deprives them of one of their most persuasive talking points (whether true or not). Still the claims persist; they’ve even begun preparing to ward off genuine skepticism spurred by the hottest year on record.

I seem to be one of very few who has said all along, repeatedly and consistently, that I’m not convinced there has been what is sometimes called a “pause” or “hiatus,” or even a slowdown in the warming trend of global temperature — let alone in global warming.

Carbon News 8/12/14: NZ’s multi-billion carbon blowout

We’re facing a $3b carbon crisis … and it could be worse

New Zealand has a $3 billion carbon headache looming – and Treasury says that’s the conservative estimate. Carbon emissions in the period 2021 to 2030 could cost the country as much as $52 billion. Official briefings to the incoming Government acknowledge that the costs of meeting emissions reductions targets after 2020 were likely to rise significantly because “our emissions are forecast to increase and carbon prices are likely to be higher”.

The country needs a carbon budget, says pressure group

A climate change lobby group is calling for a national carbon budget and legally binding emissions reduction targets. The Sustainability Council’s paper comes as it releases figures showing New Zealand is facing a carbon liability of between $3 billion and $52 billion by 2030. Drawing on Government documents and its own work, the research and advocacy trust paints a picture of a country running a creative carbon accounting process, in which carbon liabilities have been shunted off to a time when carbon prices are predicted to be much higher.

Groser has a cunning plan (but he won’t say what it is)

Climate Change Minister Tim Groser says New Zealand will “push the envelope” on post-2020 emissions reductions. But he still won’t say what that means. New Zealand has to announce its 2021-2030 emissions reduction target before the negotiations for a new international climate treaty in Paris late next year. Groser, who is now in Lima for UN climate talks, told TV’s The Nation at the weekend that the target didn’t have to be settled until the middle of next year.

Ocean heat drives surge to global warming record

It’s official, even though it won’t be conclusive for a few months yet: if present trends continue, 2014 will be one of the hottest years on record − and quite possibly the hottest of them all. Continue reading “Carbon News 8/12/14: NZ’s multi-billion carbon blowout”

Solid Treadgold, easy action (NZ still warming fast)

It’s time to return to the delusions harboured by New Zealand’s little coterie of climate cranks about the NZ temperature record. Readers may recall that — somehow — the men who lost a court case against NIWA and then folded the charitable trust they’d used to bring the case in order to avoid paying costs, managed to get their “reconstruction” of the NZ temperature record through peer review and into the scientific literature. To no-one’s surprise, they found that warming in NZ was only one third of that found by NIWA and a generation of NZ climatologists. To do that, they had to torture the data beyond endurance, as I showed at the time.

Equally unsurprising is that Richard Treadgold, prime mover of the whole fiasco, felt moved to respond in a number of typically prolix posts at his blog. His first, What Mullan actually says, purports to lay out the disputed points:

…I think these are the debating points he’s trying to make, lined up with the passages in which he makes them.

One small problem. This is not a debate. The facts are what the facts are, just as the temperature data is what it is. No amount of handwaving — or appeals to judicial authority — can change the facts of this matter. What can change is the interpretation placed on those facts, and that’s where Treadgold et al went wrong on day one.

In 2010 they decided — and explicitly told the world — that NZ’s climate scientists had been cooking the books. Everything they’ve done since has been a part of building a false narrative, a silly superstructure of misinterpretation and misdirection clumsily bolted together, designed to fool anyone sympathetic to their position. The new paper, by de Freitas, Dedekind & Brill 2014 (dFDB 2014) is just the latest effort to prop up that tottering edifice.

I have no intention of wasting time by playing along with Treadgold et al’s narrative. There are so many misdirections and misunderstandings on display in his sequence of posts that it would take a magnum opus to deal with them all. If I thought that by doing that I might change their minds — win them over to the world of climate rationality — then I would be happy to do it, but Treadgold et al are not what I would describe as rational actors. They admit no facts that are inconvenient to their world view, and show no sign of educability on climate science.

Carbon News 1/12/14: Future of work in NZ in clean tech, says Labour

Labour vows to watch work and the new economy


The Labour Party’s Future of Work Commission will include analysis of the impacts on work of climate change and the low-carbon economy. The commission was announced by Labour leader Andrew Little at a business briefing in Auckland this morning. It will be led by finance spokesman Grant Robertson, who told Carbon News that clean-tech opportunities are at the forefront of the party’s thinking.

Govt hopes Kyoto credits will cover emissions blow-out


The Government will use international Kyoto credits received in what’s known as the KP1 true-up to cover its emissions blow-out. But it doesn’t yet know how much of a help they will be.

Memo farmers: Learn to manage your methanotrophs


Farmers could cut their future exposure to carbon prices by looking after the methanotrophs in their soils, a soil scientist says.

Lima climate talks ‘stepping stone’ for universal treaty


A new round of talks in Lima is an opportunity to raise immediate awareness on climate change and lay the foundation for a new universal agreement to be adopted in 2015, says a top UN official. Continue reading “Carbon News 1/12/14: Future of work in NZ in clean tech, says Labour”
