Weekend compendium

LovelockJames Lovelock is the man who invented earth system science – or to give it the name he got from William Golding (the Lord Of The Flies man), Gaia. Very influential, in other words, and one of the gloomiest prognosticators of mankind’s future in a world where Gaia bites back through climate change. Rolling Stone has an excellent long profile of Lovelock, which includes this gem about some temporary employment during the 1980s:

He supported himself in part as a consultant for MI5, England’s top counterintelligence agency, where he developed a method to monitor the movements of KGB spies in London by using an ECD [electron capture detector, a device invented by JL] to track their vehicles.

Elsewhere:

  • The UN Environment Programme’s fourth Global Environment Outlook Report (GEO-4) makes gloomy reading. The Press puts it on the front page with the headline Man’s ‘very survival at risk’. [Herald, BBC, Telegraph [UK], full report PDF]. Our ecological overdraft is going to make Gaia unhappy…
  • She’s not helping out with CO2 like she used to either. The amount of our CO2 emissions mopped up by natural emissions is declining – which threatens to speed up warming as carbon cycle feedbacks kick in, a new study [PDF] finds. [BBC, Herald, Times [UK], CSIRO, Rabett Run, Stoat]

Tuesday linkfest

Labour weekend means just that, chez Hot Topic. Catching up with farm work, planting the vege garden, getting a sore back – all in a weekend’s work. But climate change waits for no man, so here’s a compendium of stuff that caught my attention over the last few days.

  • Contact Energy has announced plans for a huge – 218 turbine, 650MW – wind farm called Hauauru ma raki, to be built on a remote site south of Port Waikato. NZ turbine builder Windflow Technology has announced plans for new models designed to work in India and China, and Meridian has sent wind experts to Scott Base in Antarctica to advise on building wind turbines to reduce fossil fuel requirements. According to Stuff, they think it could be easier than building in Wellington.
  • Still more on the Arctic summer: the NSIDC updates its coverage with some excellent animations, while Cryosphere Today adds an archive of maps of atmospheric conditions over the summer, and introduces a web app that allows iPhone users to monitor sea ice conditions. Another reason why I want one. Technology Review visits Greenland to meet the teams measuring the melt, and down south, satellites spot a huge berg breaking off the Pine Island Glacier.
  • On the roof of the world, the Nepali Times reports Kiwi guides describing how the disappearance of ice on the planet’s biggest mountains is changing the climbs.
  • Two more good articles from TR: Fixing the Power Grid describes how big batteries (capable of supplying 1MW+ for hours at a time) can provide back up for grid problems, and Tiny Solar Cells looks at nanowire solar cells made by a team at Harvard.
  • Carbon emissions from shipping could be as much as twice those from aviation, according to a report from Intertanko. Strong growth in trade has driven emissions to 1.2 billion tonnes oer annum. Meanwhile, the Herald reports on aviation’s attempts to be seen to be more climate friendly – and Richard Branson’s efforts to beat Air New Zealand to the first use of biofuels in jets.
  • CO2 absorption in the Atlantic has nosedived, adding to concerns that the ocean carbon sink may be reducing – leaving more of our emissions in the atmosphere [University of East Anglia].
  • Coral reef specialists have issued a call to action on the impact of climate change: “We call on all societies and governments to immediately and substantially reduce greenhouse gas emissions. Without targeted reductions, the ongoing damage to coral reefs from global warming will soon be irreversible.”
  • The Daily Telegraph [UK] is in the process of becoming enthusiastically green. Latest evidence is a nifty widget – the Telegraph Earth Pulse – which monitors climate and general environment news.
  • A dairy farm can produce as much sewage as a small town (see North & South current issue), but worms can turn it all into mellow compost according to US researchers.
  • It looks like a “three-wheeled technicolour shoehorn”, but the No More Gas will do 75 mph and has a range of 30 miles. OK for getting around town, but I’d still prefer a Tesla Roadster…
  • The financial word is getting the climate message: Deutsche Bank thinks that efforts to combat climate change will drive an investment “megatrend”, Morgan Stanley estimates that global sales of wind, solar and geothermal power and biofuels could be US$1 trillion a year by 2030, and HSBC is launching a climate change investment fund for investors who want to track companies active in the field.
  • HT tends to steer clear of dsicussing peak oil, but the Guardian [UK] covers a new report that claims that we passed peak oil last year, and that global oil production will be halved by 2030. Adds a certain piquancy to energy strategy…

And on Friday night…

GoreStop press: Canterbury lose semi-final, and – in a move guaranteed to enrage global warming sceptics – Al Gore and the IPCC have been jointly awarded this years Nobel Peace Prize [BBC, New York Times]. In the citation, the Nobel committee said:

By awarding the Nobel Peace Prize for 2007 to the IPCC and Al Gore, the Norwegian Nobel Committee is seeking to contribute to a sharper focus on the processes and decisions that appear to be necessary to protect the world’s future climate, and thereby to reduce the threat to the security of mankind. Action is necessary now, before climate change moves beyond man’s control.

Congratulations to Al and all the NZ scientists involved in the IPCC process – David Wratt, Jim Renwick, Blair Fitzharris and many others.

Another Friday roundup

NzmapI’m a sucker for pretty computer graphics, especially if they’re didactic. Today’s discovery is a superb Flash animation of the sea level history of Australia and New Guinea, lovingly prepared by Monash University‘s new SahulTime project [ABC coverage here]. From the web site:

The concept of SahulTime is similar to GoogleEarth, except that SahulTime extends each of GoogleEarth’s paradigms through a further dimension in time. Satellite-style images change to reflect coastlines, the icons are time-aware, and even photographs can can be taken through a timewarp to view reconstructed ancient landscapes.

You drag a pointer back along a profile of how sea level has changed over the last 100,000 years, and watch how Australia’s coastline changes, merging with New Guinea. Fantastic. Can we have one for New Zealand, please?

Meanwhile…

  • Al Gore’s film An Inconvenient Truth has been passed by a UK High Court judge as fit to be seen by UK schoolchildren, but only with changes to the accompanying teacher’s notes to clarify nine scientific “errors”. News media are buzzing: a few samples – Herald, BBC, and Guardian (UK). The BBC’s environment correspondent provides some context, and Stoat (aka climate scientist and ice gambler William Connolley) looks at how serious the mistakes really are. The right wing roots of the court case are explained by Oil Change International, and one of the “expert” witnesses looks like it might have been the NZ CSC’s own Bob Carter. Not surprising then that former ACT MP Muriel Newman’s NZ Centre for Policy Research site is all over the issue – though she manages to find two extra bonus “errors” from somewhere. Read the judgement in full here. Real Climate’s original review supports the judge’s finding that AIT gets the basic science right.
  • New Scientist reports on a Canadian study that finds that to keep global temperature under the EU’s target of 2C above pre-industrial levels, cuts of 90% of emissions will be needed by 2050, much deeper than the 50% reductions already promised.
  • The new edition of popular computer game SimCity is to feature global warming, offering players high and low carbon energy options – sponsored by BP. A sign of the times….

ETS reaction #2

Wp-Content Uploads 2007 09 Nzets1Two very perceptive pieces of analysis over the last few days,and one deeply misguided one. Rod Oram in the Sunday Star Times takes a look at how nitrification inhibitors could be a major incentive for dairy farmers to get involved in emissions reductions sooner rather than later, and Colin James in the Herald rather gloomily acknowledges the realpolitik of international negotiations:

The odds are that humanity doesn’t think it matters, at least not enough to forgo significant amounts of its material gains or prospects. The odds are that humanity won’t really change its mind until (or if) climate change starts to have effects that cut significantly into material gains and prospects, the necessaries and luxuries of life, and people see it as the cause: that is, when it ceases to be a moral issue and becomes an economic one. That point has not been reached. So world politicians are likely to come up with a suboptimal arrangement to apply when the Kyoto Protocol ends in 2012 and to implement it suboptimally. And so, if the climate change high priests’ measurements and predictions are right and warming isn’t offset by radical new technologies, there is a rough ride ahead.

On the other hand, Roger Kerr of the Business Roundtable in the Dominion Post, grudgingly admits that the ETS looks “responsible and moderate
