Down down

New Scientist has posted this remarkable footage of a camera being lowered down a moulin in Greenland, and reveals that Konrad Steffen’s team, moulin explorers extraordinaire, are inventing a new extreme sport:

Later this year, the team will be boldly going where no researchers have gone before. Under the guidance of expert climbers, they plan to descend deep into a moulin in person. They will leave temperature and flow sensors along the way, so they can track how the tunnel changes throughout the year.

Steffen’s team also released hundreds of special rubber ducks into moulins, but none have yet appeared at the edge of the ice sheet. He fears they may have been ground to pieces by the moving ice. More at the Guardian.

Two tribes

Cheatin Heartland On the one hand, in New York, the Heartland Institute‘s climate crank talking shop, where scientists of the immense probity of Richard Lindzen were happy to share a stage with proven fabricators of data like Christopher Monckton, has drawn to a close. Terry Dunleavy, head honcho of NZ’s climate crank coalition has given his presentation, and no doubt Muriel Newman is happy that her NZ Centre for Policy Research sponsorship of the event has been fruitful. The crank blogosphere has loved the attention, and the great communicator himself (step forward Bob Carter) has been positively chortling about the event in his posts at Quadrant Online.

On the other hand, a proper conference, Climate Change: Global Risks, Challenges and Decisions is just getting under way in Copenhagen. Real scientists from all over the world, leaders in their fields, are gathering to present the latest research findings. The objective is to provide a comprehensive update to the findings of the IPCC’s 2007 report, so that policymakers can go into the final phase of negotiations for a post-Kyoto deal with a clear picture of what the science is telling us about the climate system. Conference organiser, Prof Katherine Richardson of the University of Copenhagen provides more background in this interview at Nature Reports: Climate Change.

I’ll be covering news from the conference as it emerges, but the big news from day one: expect sea level rise of at least a metre by the end of the century. BBC coverage here, plus TimesOnline, the Herald reprints an Observer preview, New Scientist, and the conference press release for day one.

Two other interesting stories from day one (which I will return to, at some point): the “tipping point” for complete loss of the Greenland ice sheet may be further off than thought, and a French researcher gave a dire warning about permafrost carbon emissions.

More than dreaming

My review of Broecker and Kunzig’s book Fixing Climate drew attention to the work of Klaus Lackner, a physicist at Columbia University who has been working on ways of scrubbing CO2 out of the atmosphere for sequestration. Lackner considers sequestration the harder problem of the two and believes that the only method adequate in the long-term is mineral sequestration, achieved by hurrying along the natural process geochemical weathering whereby rocks react with CO2, removing it from the air to form limestone and other carbonates.

Flying high

MarionArawata.jpgNZ glacier experts are flying round the Alps at the moment shooting glaciers (with cameras and GPS units), conducting their annual ice mass balance audit. TV One sent a reporter to see what Trevor Chinn and Jim Salinger were up to, and on Sunday broadcast a nice little item about the process. Highlights: Jim Salinger rolls out his new favourite measure of volume, the Rangitoto, and Trevor Chinn can be heard commenting “They’ve bloody wrecked a glacier”… Last year’s survey results here, with link to background article.

Goin’ back

FrenchPassVortex.jpg You may have thought I was on holiday, but in reality I was gathering blog-relevant material while eating and drinking too much on a catamaran tootling round D’Urville Island. I took a look at DOC’s new bush regeneration for carbon offsets project in Greville Harbour (from the beach), assessed fish stocks (with a rod and line) marvelling at barracouta chewing blue cod before they could be hauled into the boat, saw a seal tossing an octopus snack, enjoyed the company of Dusky dolphins, and ate rather too much crayfish. I’m a bit late for Seaweek, but given I’ve been on the sea most of the week, it deserves a plug.

Readers may recall I posted about von Karman vortices in clouds last week, and as Jamarh navigated French Pass, I saw another fine example as the tide flowed past the channel marker in the middle of the strait. You can clearly see the vortices forming as whirlpools downstream of the pillar.

And now, after a week without radio, TV or cellphone contact, I have some catching up to do…
