The canary croaked

From AP (via CNN): “The Arctic is often cited as the canary in the coal mine for climate warming,” said Zwally, who as a teenager hauled coal. “Now as a sign of climate warming, the canary has died. It is time to start getting out of the coal mines.” The annual American Geophysical Union meeting in San Francisco is bringing bad news about the Arctic – most of it listed in the foregoing linked article. One paragraph is particularly shocking:

Still to be released is NASA data showing the remaining Arctic sea ice to be unusually thin, another record. That makes it more likely to melt in future summers. Combining the shrinking area covered by sea ice with the new thinness of the remaining ice, scientists calculate that the overall volume of ice is half of 2004’s total.

In three years, half of the summer ice has gone. In Hot Topic I suggest that it might all be gone in my lifetime – and I thought I was being pretty daring, given that the IPCC talks about the end of the century. One ice modeller who has been predicting an early demise for the summer sea ice is the US Navy’s Wieslaw Maslowski. From the BBC:

“Our projection of 2013 for the removal of ice in summer is not accounting for the last two minima, in 2005 and 2007,” the researcher from the Naval Postgraduate School, Monterey, California, explained to the BBC. “So given that fact, you can argue that may be our projection of 2013 is already too conservative.”

RealClimate is providing coverage of AGU highlights (here, here, here and (update – sea ice specific) here. The Herald runs with a very US-angled Reuters story. As I’ve pointed out before, the consequences of the loss of summer sea ice in the Arctic for northern hemisphere climate is not known, but I would expect that there’s some urgent work being done to find out. We’re into the land of the unknown unknowns, and there’s nothing we can do to stop it.

Something 4 The Weekend

Bali continues to make headlines. The rough positions are becoming clear. China’s playing hardball – no mandatory cuts, West has to cut first and most deeply. The New York Times‘ Andy Revkin has a couple of good Bali posts on his blog: the first suggests that the IPCC may have to revise its goal for the next report – updating AR4 for the conclusion of the post-Kyoto process in 2009, while the second looks at what’s going on around the negotiations. Meanwhile, 200 scientists from around the world, coordinated by the Climate Change Research Centre at the University of New South Wales, issued a statement calling on the conference to aim for emissions cuts of at least 50% by 2050 [Herald, Globe & Mail (Canada)].

Meanwhile, there’s lots more below the fold (as they say on the broadsheets)….

It’s not just the cows

It’s been a quiet few days chez Hot Topic, as the sun’s been shining (until today), the farm’s been calling and friends have been dining, but I can’t pass over this piece of news. A new web site called CARMA – Carbon Monitoring for Action – was launched last week [Science Daily ]. It pulls together information on carbon emissions from the 50,000 power plants around the world and the 20,000 companies that run them, and ranks countries, regions and cities on their emissions. So what happens when you have a look at New Zealand?

As you might expect, Huntly dwarfs the competition, credited with producing 7.6 million tons of CO2 per year, but if you click on the emissions intensity tab (far right) – the amount of CO2 per unit of power generated – a couple of Fonterra factories top the charts. Step forward Waitoa and Edendale – NZ’s most intense/least efficient emitters of CO2. Can’t be good for their performance on Fonterra’s internal “carbon account“. CARMA is a treasure trove of information, well worth a long look.

I don’t like Mondays

Lady Young, head of the UK’s Environment Agency, thinks that coping with climate change demands wartime urgency, as the Telegraph [UK] reports:

“This is World War Three – this is the biggest challenge to face the globe for many, many years. We need the sorts of concerted, fast, integrated and above all huge efforts that went into many actions in times of war. We’re dealing with this as if it is peacetime, but the time for peace on climate change is gone – we need to be seeing this as a crisis and emergency,” she said.

Meanwhile, the Observer covers a new report from a peace group:

This stark warning will be outlined by the peace group International Alert in a report, A Climate of Conflict, this week. Much of Africa, Asia and South America will suffer outbreaks of war and social disruption as climate change erodes land, raises seas, melts glaciers and increases storms, it concludes. Even Europe is at risk.

Greenhouse gas emissions continue to increase, and the International Energy Agency sees “inexorable”growth in energy demand over the next 30 years with a risk of more coal being burned. It does suggests a 450ppm CO2 limit might be achievable, but:

“Exceptionally quick and vigourous policy action by all countries, and unprecedented technological advances, entailing substantial costs, would be needed to make this case a reality.”

Not much hope of that. And the China Post says EU officials reckon that China will reject binding limits on emissions in any post-Kyoto deal. The words “hell” and “handbasket” spring to mind…On the upside? Bryan Appleyard in the Sunday Times [UK] looks at options for “fixing” climate through technology (well worth a read), scientists at Harvard and Penn State reckon they’ve found a way to speed up a natural weathering process to neutralise ocean acidity and remove carbon from the atmosphere, and Technology Review reports on a Dutch biofuel company working with a California-based venture capital outfit to develop catalysts that can turn organic matter such as waste wood into biocrude – chemicals that can be processed to make biofuels. If you’ve got money to invest, the Observer [UK] reckons that one of a new breed of green investment funds might be a good place to put it.

Revenge of the zombie facts

Dr Vincent Gray is one of the most active of NZ’s little band of cranks. He’s been publishing his “envirotruth” newsletter since the ’90s, always brimful of climate scepticism, and has been a stalwart reviewer of IPCC reports. His most recent contribution to the IPCC process was to make 1,898 comments on the final draft of the Working Group One report – 16% of the total, and, perhaps unsurprisingly, he accounted for 95% of the comments rejected by the authors. Vincent’s offerings are the backbone of the NZ Climate “Science” Coalition site, and I always enjoy reading them.

His most recent, Problems With Surface Temperature Data [PDF], is typical. He asserts it’s impossible to arrive at a meaningful figure global temperature, prefers satellite data but doesn’t believe it, and then states that “Since the amalgamated surface record is unreliable, an indication of temperature change over the past century can be obtained from well-maintained local records. Attempts to correct for the many errors, though not entirely successful, give records of some credibility.” (Otherwise known as the cherry-pickers charter). He then disinters a 1994 paper that found a 60-65 year cycle in global temperature (but I thought that was meaningless) if the data is “detrended”. One wonders what trend was removed. Perhaps the long term underlying rise in temperature? If we ignore the data, it goes away. Magical thinking at its finest.

[UPDATE 6/11/07: NASA’s excellent Earth Observatory posts a very interesting article about James Hansen and the development of the global temperature record. There’s a superb animation of atmospheric flows from space on page 2.]

But the most interesting part of Vincent’s report is the note at the end: “This paper is part of “The Science is not Settled: Major Issues Remain Unresolved by the IPCC: A Report of the NIPDD” (sic) (Non-governmental International Panel on Climate Change) to be published by the Science and Environmental Policy Project, Arlington Virginia.” The NIPCC? Seems this is something Fred Singer at SEPP has set up as a counterblast to the IPCC, and its report is due soon. From Fred’s The Week That Was for Sept 1st:

Highlights of the NIPCC Report

  • Demonstration of the insignificance of human contribution to current warming – using the ‘fingerprint’ method – and why future anthropogenic warming is negligible
  • Why climate models do not agree with observations – the role of feedbacks
  • Evidence that solar activity controls most climate change on a decadal time scale
  • Evidence that future warming will not accelerate sea level rise appreciably
  • No evidence for more storms, hurricanes, droughts, and floods as climate warms
  • How we know that a warmer climate is better than a colder one
  • Evidence that the Medieval Period was warmer than today
  • Evidence that pre-1940 warming was not anthropogenic
  • Problems with data quality and special problems with sea surface temperatures
  • Uncertainties about the CO2 budget, past and future – and of future emission scenarios
  • Changes in ocean heat storage, glacier length, and sea ice coverage indicate climate change – but not whether the cause is anthropogenic or natural

That’s a mind-boggling list. If all the papers show the – how shall I put it politely – “rigorous” approach to the science that Dr Gray demonstrates, the NIPCC report will be a real paradigm shift. Or perhaps not.
