The Science Show reported on a new survey of East Antarctica published in nature.
probably something like the Northern Territory area was actually below 500 metres below sea level, and if you look at the deepest bits, something like the size of Tasmania was more than one kilometre deep.
The implication is that at some stage the sheet will melt faster than previously thought.
The lakes are formed through thermal heat from below.

New report on the risk of climate change to Australia’s coasts
Launching the new report Climate Minister Greg Combet says:
“The sea level rise of up to 1.1 metre, which is at the high end of the scenarios that the scientists are suggesting, would have a devastating impact, as much as $266 billion worth of potential damage and loss,” he said.
The report found:
up to 274,000 homes are at risk of inundation and erosion along with over 8,000 commercial buildings, and up to 35,000 kilometres of roads and rail around the country.
I’m not sure about 1.1 metre being “at the high end of the scenarios that the scientists are suggesting”. If you go here it looks more like a midpoint.

The Tyndall Centre in a study for the 2006 Stern Review found that the damage costs for a 1 metre rise are 7 to 12 times greater than for a 50cm rise. They also found that 1m would displace 145m people world-wide.
In case you are wondering, Arctic ice coverage is tracking below 2007 levels.
The modelling shows the carbon price only slugs economic growth 0.1 per cent, leaving growth per person at 1.1 per cent.
“Our economy will continue to grow solidly while making deep cuts in carbon pollution,” he told the National Press Club.
He also says that employment will increase by 1.6 million jobs by 2020.
Warwick McKibbin says that’s garbage (“unfortunate” was the actual word he used) because only his model contains unemployment. Other models assume by definition that anyone displaced will get a job.
Food insecurity again
…some of the countries most sensitive to climate change and least able to cope with it, also have among the highest rates of population growth…
in a world of unrestricted greenhouse gas emissions, where the temperature rise of 10°F by centuries end is not even the worst case, but just business as usual.
Powering down your computer
The new EnerJ system could cut computer power consumption by up to 90 percent.
So far gains of up to 50% have been achieved by supplying less power to regions of the chip that are performing processes that don’t require absolute precision. However, further savings could be made by also applying the system to software.
I’m told that computers generate about the same emissions as air travel, so the savings are significant.
Thanks to John D for this and several other items.
Turning heavy-duty construction, mining and agricultural machines into hybrids
And thereby saving up to 50% of energy used according to Finnish researchers.
braking was not their primary energy-generation source. Instead, the majority of the energy came from work-related activities such as deceleration, and the lowering of loads.
G77 and China want the Kyoto Protocol extended
I haven’t heard much yet coming out of the UNFCCC climate talks in Bonn, but the G77 plus China have said they want the Kyoto Protocol extended. You will recall that the G77 now includes 131 countries.
Japan, Russia and Canada have all said they won’t accept new binding targets under Kyoto unless all major economies are bound, which includes China and the US. The US can’t, with the deniers controlling Congress, and China won’t – well, not yet and definitely not without the US. So in that sense we’re heading for the same old in Durban in December.
In case you missed it on the earlier thread:
The Productivity Commission has backed the Federal Government’s claims that other world economies are taking significant measures to combat climate change.
It says price-based mechanisms, such as the one planned for Australia, are the most effective and least costly way to reduce carbon pollution.
The key question was not what Tony Abbott thought about it; rather what Tony Windsor thought, because he asked for the report to be done. Tony Windsor on Lateline:
But it does answer two substantive questions that I raised probably six months ago now; one being is the rest of the world doing something, or is it doing nothing? I think the answer is yes, the rest of the world is moving in a direction.
The second one I think has been obvious to anybody in recent months, is that if you are going to address this issue, a carbon pricing mechanism is the way to address it.

Australia is considering killing feral camels to tackle climate change, thereby saving 1 million tonnes of CO2 equivalent.
Also the Dalai Lama is here promoting peace of mind and the notion that we should act in the general rather than the national self interest in combating climate change. I wonder what he thinks about killing camels.
