Marvellous distempered: the Copenhagen diagnosis

by Gareth 25 November 2009

The Copenhagen climate conference (COP15) opens its doors in a little under two weeks. To update participants on the science of climate a new assessment report, The Copenhagen Diagnosis, was released yesterday, and it makes grim reading. Designed to inform “a target readership of policy-makers, stakeholders, the media and the broader public” about the evidence [...]

Titanic days

by Gareth 11 September 2009

Awesome (defined as extremely impressive or daunting; inspiring great admiration, apprehension, or fear) time-lapse pictures of the calving face of the great glacier at Ilulisat, Greenland pouring ice into the ocean — the single biggest ice discharge of any northern hemisphere glacier. Greenlanders reckon this is where the iceberg that sank the Titanic originated. The [...]

More than a metre

by Bryan Walker 10 September 2009

Sea level will rise by more than a metre by 2100 according to the authors of the third chapter in the World Wide Fund for Nature’s new Arctic report, introduced by Gareth a few days ago. Eric Rignot, one of the two authors of the chapter, is principal scientist for the Radar Science and Engineering [...]

(Arctic) Change is now

by Gareth 5 September 2009

The World Wide Fund for Nature (WWF) has just published a new report on climate change in the Arctic — Arctic Climate Feedbacks: Global Implications [PDF], and it’s a fascinating read. Over the last two years I’ve blogged regularly on the changes being seen in the Arctic — sea ice reductions, melting of the [...]

Ice concentrates ministerial minds

by Bryan Walker 30 July 2009

Connie Hedegaard, the livewire Danish Minister for Climate and Energy (yes they are twinned in Denmark – would that they still were in NZ), will not be to blame if the Copenhagen talks, which she is to host, founder.  I have been watching the BBC’s Hard Talk programme the last couple of evenings.  Interviewer Stephen [...]

Wouldn’t it be ice

by Gareth 29 July 2009

Pictures from my new favourite blog, Meltfactor.org, where Jason Box of the Byrd Polar Research Centre at Ohio State is posting from the Greenpeace expedition to the Petermann glacier in NW Greenland. The pictures are stunning (above shows fracturing on the end of the ice tongue) — and the insight to what’s going up there [...]

On an island

by Gareth 24 July 2009

NASA’s Earth Observatory is without doubt one of my favourite web sites. As I write, the above view of sea ice off Baffin Island (or a version of it) is their Image of the Day, and aside from the obvious beauties of the swirls of melting sea ice (memorably described in a comment at RealClimate [...]

First we lose Manhattan…

by Gareth 16 July 2009

It looks as though the Petermann Ice Tongue in northern Greenland is about to lose another major chunk of ice. This New Scientist video (accompanying text here) shows a team working on the tongue, documenting events as they happen. They expect a major break-up event within weeks:

When this happens, an island of ice the size [...]

Gone too soon

by Gareth 26 June 2009

The June Sea Ice Outlook forecasts for the Arctic sea ice September minimum extent have been released today by SEARCH. Most groups are picking a minimum close to last year’s 4.7m km2, but the melt season is starting with an unusually small amount of multi-year ice. The report suggests that there is “a small [...]

Southern freeze

by Gareth 12 June 2009

While we’re on the subject of ice, Australia’s Antarctic Climate & Ecosystem Cooperative Research Centre today launched two new publications: Polar ice sheets and climate change: global impacts [PDF], and Changes to Antarctic sea ice: impacts [PDF]. Described as “position analyses”, the papers provide an excellent overview of the current state of our understanding of [...]
