Being economical with the truth, or lying through her teeth?

homer.jpg Politicians are skilled at manipulating facts to convey any impression they desire. It’s called spin, and in its worst cases truthiness – nicely defined by the man who invented the term, Stephen Colbert of The Colbert Report: “We’re not talking about truth, we’re talking about something that seems like truth—the truth we want to exist.” Out in wingnut land, they want to believe that global warming is not real. So Muriel Newman at her NZ Centre for Political Research web site starts spinning the facts and, in the middle of a rambling attempt to justify a recent climate crank call for a joint Australia-NZ Royal Commission on climate change manages to come out with the following:

Anyone who claims that the science on global warming is settled is wrong. There is now growing evidence that that the earth is not warming but cooling: since the 1970s the glaciers of the Arctic, Greenland, and the Antarctic have been growing, and since 1998 average world temperatures have been falling with 2006 cooler than 2005 and 2007 cooler still.

This may be what Muriel fervently believes, but it is also completely untrue. So untrue, in fact, that saying it in an attempt to influence public policy amounts to lying. Sadly, in the echo chamber of truthiness around her web site, she gets taken at face value. Out in the wider world, it simply leaves her credibility in tatters.

Clearing the decks #2

Time to catch up with some climate stuff that I’ve accumulated over the last couple of weeks.

  • Auckland lawyers Lowndes Associates have become the first legal firm in NZ to achieve CarbonZero certification – which means that they’ve taken steps to measure their carbon emissions, actively reduce them, and then have bought credible offsets to cover the rest.
  • The first hints of NIWA’s new regional climate projections are beginning to emerge. By the end of the century, Southland could be as warm as today’s Bay Of Plenty. And Jim Salinger, who first noticed that we were warming up, was given a good profile by the Herald.
  • A belated mention for the Be The Change campaign, a climate change awareness campaign that trundled up the country in a bus in the last couple of months of the year. As the SST reported: “From Bluff to Kerikeri, the Be The Change bus tour is a Greenpeace, Oxfam, and Forest and Bird campaign to get ordinary New Zealanders working to stop climate change.”
  • The NZ Stock Exchange’s carbon trading market, TZ1, is aiming for a mid-year launch, and has appointed former Vector CEO Mark Franklin to head up the operation.
  • The German developed SkySail system for sail-assisted shipping (as featured in HT) is about to get an extended sea trial on a voyage from Europe to Venezuela, Boston and back: “Under favorable wind conditions, the 160-square meter kite shaped like a paraglider is expected to reduce fuel costs by up to 20 percent or more ($1,600 per day) and cut, by a similarly significant amount, its carbon dioxide emissions.” [Yahoo News, Guardian [UK]] There’s lively discussion of the pros and cons over at Frogblog.
  • Some new science: another study confirms that IPCC sea level rise projections are conservative – pointing out that in the last interglacial levels rose by up to 1.6m per century. Work on the Paleocene Eocene Thermal Maximum 55 million years ago, considered the best historical analogue for the present situation, confirms that initial warming caused massive carbon cycle feedbacks that boosted temperatures even further. In the Arctic, warming peaked at about +24C.
  • Some turn of the year roundups: Technology Review covers the year in energy and nanotech (good news for batteries), The Independent [UK] rounds up the climate news, New Scientist brings an earth science perspective, while NOAA presents a nice graphic of the year’s extreme weather events.
  • At Gristmill, Tom Athanasiou takes a perceptive look at the post-Bali world, and Joe Romm explores some of the latest thinking on what sort of target we should be aiming for. Bottom line: we may already be overshooting. And at the New York Times, Jared Diamond explains the collision between population growth and consumption growth. There’s a crunch coming.
  • Finally, NZine reviewed Hot Topic, and liked it: “I strongly recommend everyone to read this book, but especially recommend it to those who make decisions on action to counter the impact of global warming and those who are able to influence the thinking of others on this issue.”

(Pod)Cast Your Fate To The Wind

Two good podcasts to catch up on before the avalanche of Bali-related news hits. Nature Reports Climate Change launches a new podcast hosted by editor Olive Heffernan (RSS, mp3), using Nature’s clout to get interviews with key scientists. Should be worth a regular listen. And Chris Laidlaw’s Sunday Morning programme included an excellent pre-Bali interview with Rajendra Pachauri, the IPCC’s head honcho, and David Wratt from NIWA (stream, RSS). Chris makes up for his gentle Lawson interview by suggesting that the good lord might have been living in a fool’s paradise. Indeed.

Going up

How much will sea level rise over this century? “Don’t know” is a good answer. “Not much” is looking like a bad answer that’s getting worse by the month. Last week a group of Northland Conservation Corps workers rode on a hikoi along Ninety Mile Beach to draw attention to the issue:

Tutor Mike Wikitera and his team erected five signs marking predicted sea level rises by 2030. The group, who rode horses to avoid adding to greenhouse gas emissions, erected the first sign at Shipwrecks Bay and placed the last one at Waipapakauri beach on October 30.

But what are the “likely levels” by 2030? The IPCC’s latest report projects between 18cm and 59cm by the end of the century, but only by excluding a very big unknown – how much ice will melt in Greenland and Antarctica. As more evidence of dramatic melt in Greenland arrives, it’s getting increasingly difficult to rule out multi metre rises. The latest number comes from Professor David Vaughan of the British Antarctic Survey, quoted in the Daily Telegraph [UK]:

Prof Vaughan says the main message is not to panic – the effects of melting will be gradual, in the order of three metres per century if the evidence of the past 20,000 years is anything to go by.

Three metres per century? That’s towards the top end of current speculation. 30cm every ten years, ten times the current rate, compares with 17cm over the last century. Prof Vaughan’s right about panic. It’s not a good option, but extreme concern is certainly justified. For some dramatic pictures of what might happen, check out this Greenpeace report on climate change impacts on Spain, timed to coincide with the IPCC meeting in Valencia to ratify the AR4 synthesis report. To see what 3m might mean for NZ, go here and zoom in on your favourite bit of beachfront property. NIWA’s current advice to local government is to allow for 50cm by 2100. That’s in need of considerable upward revision.

Meanwhile, the impact of sea level rise is not just high tides and wet feet. Salt water intrusion into fresh water coastal aquifers can be bad news for agriculture and drinking water – and the problem may be worse than previously thought, according a new study reported by Science Daily. The BBC covers one of the areas at most risk – Bangladesh – in a new series, documenting a boat journey through the country.

Float on…

A big float story slipped under the HT radar a month ago. Luckily I noticed the NZ connection in a recent release from the Scripps Institute in California – designers and builders of many of the Argo float network – and so I bring you news of the completion of this ocean monitoring system and the big role played by NIWA and its research ship, the Kaharoa, in deploying the floats. Better late than never…
