Australian greenhouse graphs
The ABC has a graph of Australia’s greenhouse gases. I’ve extracted the pie chart here:
The figures are for 2009-10 and exclude land use, land use change and forestry (LULUCF) which in 2005 was 6%.
This graph is of changes, 1990-2008 (including LULUCF), showing Australia and NZ in a bad light, but Turkey is the runaway champion. I suspect outsourcing of manufacturing from the EU.
There’s an interesting champagne glass image Jo Abess’s blog (scroll down) but I’m not sure of it’s pedigree.
Arctic ice death spiral
Climate Progress looks at what’s happening with Arctic ice.
Sea ice extent is about where it was in 2007 and 2010. The next few months will tell whether records are broken. I’ll freeze the graph from here:
Volume is a real worry.
PSC reports, “Monthly averaged ice volume for June 2011 was 15,700 km3. This value is 37% lower than the mean over this period, 47% lower than the maximum in 1979, and 2.5 standard deviations below the trend.
In November, Rear Admiral David Titley, the Oceanographer of the Navy, testified that “the volume of ice as of last September has never been lower” in the last several thousand years.”
Titley expects to see four weeks of basically ice free conditions in the mid to late 2030s.

Worst case sea level rise
This one goes back a while but the Government has taken to referring to 1.1m as the worst case sea level rise expected by 2100. This was the metric used in the latest official supplementary report.
They must know this is wrong and David Spratt called them on it in an article in Crikey. Go to Climate Code Red, click on “blog” and look for the entry of 8 June 2011. This is how 1.1m looks against recent scientific articles:
At 1.1m the estimated damage to buildings and infrastructure is $266 billion. Spratt points out that with 2 metres that figure more than doubles.
Ocean carbon sink is waning
That’s according to a new study of the North Atlantic.
The scientists are now going to study other oceans to see whether the same conditions apply, as they would expect.
Food prices stay high
World food prices spiked early in 2011 and have stayed high pushing millions into extreme poverty.
Of course there are reasons other than climate change, but a link does seem evident in East Africa.
Forests and carbon credits
The question has been raised as to whether the carbon accumulated in Tasmanian forests saved from logging can generate funds as carbon credits. Towards the end Pep Canadell, CSIRO scientist and Executive Director of the Global Climate Project says:
New data is showing that forests around the world and that includes forests as vigorous as the ones in Tasmania are removing a third of the total fossil fuel emissions that are emitted every year.
So… forests and the conservation of forests are at the forefront of climate change mitigation.
But then, this!
From ABC News:
US scientists have found that the more carbon dioxide goes into soil, the more the soil releases other, more potent, greenhouse gases.
The study, published in the science journal Nature, found that plants taking up more carbon dioxide resulted in an accelerated production of nitrous oxide and methane.
Trees still have value, but 20% less than previously thought.
What are the Brits up to?
I haven’t been following closely what the Brits are doing, so I was excited when this caught my eye. £110 billion ($175 billion) worth investment in low-carbon electricity is a lot of money, especially in a busted economy. I can’t breach the paywall, so I called into The Guardian and found this:
The reality is that the government is not serious about its green agenda. In recent weeks they have scrapped the zero-carbon homes scheme, abandoned plans for a network of electric car charging stations, and now delayed the green deal. A recent survey of readers of the ConservativeHome website named the green deal as one of their most disappointing policies. Only Decc ministers within government ever talk about climate change. As we see from this turn of events, that is just hot air.
But that was a week earlier and from Meg Hillier MP, the shadow energy secretary. So I checked out The Independent and came up with this:
The ultra-free market which has been in place since electricity was privatised 20 years ago is to be drastically modified, with the Government offering generating companies long-term contracts at fixed prices to produce low-carbon power – that is, from renewable sources and nuclear installations. Going back to what is effectively a form of central planning is seen as essential to attract the huge investment – £110bn over the next decade – which is needed to replace Britain’s ageing energy infrastructure.
The Government offering generating companies long-term contracts at fixed prices, central planning seen as essential, what can they be thinking?!!
