IPCC AR5 completed: science has spoken – cut deep, cut soon

The IPCC’s Fifth Report process reached its climax in Copenhagen yesterday with the release of the final “synthesis” report (download here), which pulls together all the strands from the three working group reports on the physical science (Working Group 1), climate impacts (WG2) and how to go about dealing with the problem (WG3). Launching the report, UN secretary general Ban Ki-moon was blunt:

“Science has spoken. There is no ambiguity in their message. Leaders must act. Time is not on our side.”

Given that it’s based entirely on the work done for the underlying reports, there are no surprises the synthesis report for anyone who has been following climate news over the last year, but what is striking is the emphasis on the need for rapid and deep cuts in fossil fuel emissions – and a corresponding steep increase in investment in renewable energy sources. Ban Ki-Moon emphasised the point in a comment aimed at investors:

“Please reduce your investments in the coal- and fossil fuel-based economy and [move] to renewable energy.”

Writing in the Guardian, Bill McKibben notes an increase in the urgency of the language being used:

This week, with the release of their new synthesis report, [scientists] are trying the words “severe, widespread, and irreversible” to describe the effects of climate change – which for scientists, conservative by nature, falls just short of announcing that climate change will produce a zombie apocalypse plus random beheadings plus Ebola. It’s hard to imagine how they will up the language in time for the next big global confab in Paris.

The Guardian’s coverage is – as always – exemplary. In addition to Damian Carrington’s news report, they also give good graph. See also the BBC, and Stuff – who take the AP coverage.

New Zealand’s climate change minister Tim Groser issued a press release to welcome the report:

It is the best scientific assessment of climate issues available. I’m delighted that New Zealand scientists have contributed to this body of knowledge.

If that’s really the case, why is Groser enacting policies which are currently pointing NZ towards a 50% increase in emissions instead of deep cuts? Perhaps he should be listening to Ban Ki-moon when he says “”There is a myth that climate action will cost heavily, but inaction will cost much more.”

NZ cranks finally publish an NZ temperature series – but their paper’s stuffed with errors

You can’t teach old dogs new tricks, it seems — certainly not if they’re gnawing a much loved old bone at the time. The lads from the NZ Climate Science Coalition — yes, the same boys who tried to sue NIWA over the New Zealand temperature record and lost, and who then folded a trust to avoid paying court-ordered costs — have finally found a learned journal gullible enough to accept and publish their shonky reworking of NZ’s temperature record. Earlier this month Environmental Modelling and Assessment published A Reanalysis of Long-Term Surface Air Temperature Trends in New Zealand by CR de Freitas & MO Dedekind & BE Brill (DOI 10.1007/s10666-014-9429-z).

My attention was drawn to dFDB 2014 by an NZCSC press release, and yesterday Richard Treadgold, the man who kicked off the whole sad affair five years ago, posted a disingenuous and misleading article about the paper at his blog. As you might expect given the authors, the paper does not call for an upward revision in the amount of warming NZ has experienced over the last century. The abstract concludes with the following:

Current New Zealand century-long climatology based on 1981 methods produces a trend of 0.91 °C per century. Our analysis, which uses updated measurement techniques and corrects for shelter-contaminated data, produces a trend of 0.28 °C per century.

As you might also expect, given the authors and their respective track records, the paper is riddled with schoolboy howlers and outright misrepresentations. It would probably never have seen the light of day without the assistance of Chris “Pal Review” de Freitas and his undoubted ability to steer tosh to publication.

Carbon News 28/10/14: oil drilling, honey and crowd-funding green coke

Hunt for oil anchors govt’s environment plan

The National Party is leading off its environmental package for its new term in power with plans to encourage more oil exploration — despite the burning of fossil fuels being the single biggest cause of climate change.

Honey hits the jackpot for steep-land believer

In 2010, Taranaki farmer Neil Walker was enthusiastic about the potential for a combination of carbon farming and beekeeping to rejuvenate steep-land farming. Four years on, he is still buying cheap land and planting it in tree crops, despite carbon prices being less than a third of what they were back then.

Green-coke pioneer puts faith in public-funding

Clean-coal company CarbonScape is the first clean-tech company in New Zealand to use crowd-funding to raise capital. The Blenheim-based start-up launched a bid last week on the Snowball Effect platform to raise at least $400,000 dollars.

Good tyres tread lightly on the earth

New Zealand could cut greenhouse gas emissions by 6000 tonnes a year by installing fuel-efficient tyres on the nation’s fleet of light vehicles. And at the same time, businesses and private-vehicle owners could shave up to 7 per cent off their fuel bills.

Food, Fossil Fuels and Filthy Finance

droughtIt is depressingly apparent that powerful forces in the global economy are set to carry on with the exploration for and use of fossil fuels as a primary source of energy for decades to come. Oxfam has produced a report identifying the confluence of fossil fuel companies, governments and investors which givers momentum to the disastrous course along which we are being impelled.

Food, Fossil Fuels and Filthy Finance pulls no punches. It points to the evidence from the Tyndall Centre that, in the absence of an unprecedented change in the global use of fossil fuels, we are heading for a global temperature rise of 4 to 6 degrees by century’s end.

Warming at this rate would leave hundreds of millions of the world’s poorest people at risk of severe hunger and drought by 2060. Even 2 degrees is going to have widespread human impacts and cause serious setbacks to development. The ‘hunger costs’ of fossil fuels are set to be the most savage impacts of climate change for millions globally. Farmers in many African countries are likely to see decreases in yield decade by decade, in spite of adaptation measures. The report details much more by way of cascading adverse impacts on populations least equipped to cope with them. It also points to severe economic and business risks in store for the developed countries as climate change begins to bite in their regions.

TDB Today: Reasons not to be cheerful, Part #272b

In my post at The Daily Blog this week I take inspiration from the great Ian Dury, and reflect on the disconnect between political ambition and the state of the climate system as it continues to warm. It will be my last post at TDB for a while – for definitions of “a while” that include the time to write a book, refocus on Hot Topic, prepare the farm for the drought I fear we’re heading towards, and (with luck) harvest lots of truffles and make some damn fine wine…
