For many in Australia on climate change Bob Carter is the man. Tamino at Open Mind got access to his slides and took a look at how he does temperature trends. Turns out he doesn’t. What we get is the most outrageous and blatant cherry-picking.

John Abraham took a look at how Monckton cites scientific literature on the Mediaeval Warm Period. Abraham emailed a sample of the cited scientists to find Monckton achieved perfect score for misrepresentation.
Temperature during the last 10 years
The Stern Review showed a 2006 multi-year running average temperature graph from the Hadley Centre showing a clear upward trend. The Pew Centre has the same graph overlaid with one of atmospheric CO2:
If you focus on the last decade some scientist now refer to an “observed slow-down” of warming, more evident in the Hadley record which doesn’t include the polar regions.
Skeptical Science looks at the reasons from new research. The main answer, not surprisingly, is “a big jump in sunlight-reflecting sulfate aerosol pollution, mainly through coal burning”. This effect is expected to give way to the longer term effect of CO2 in the future, even if the Asians don’t clean up their aerosol pollution. There was also a “small drop in sunlight reaching the Earth as part of the natural solar cycle, coupled with more episodes of La Niña (natural globally cool episodes)”.
Remember, Carter ‘showed’ that there had been no warming since 1979.
Strong action on renewables
Courtesy of BilB on the last CC thread, Robert Rapier updated on the Renewables 2011 Global Status Report. The top five countries for non-hydro renewable power capacity were the United States, China, Germany, Spain, and India. Developing countries are making an increasing effort.
Renewable capacity now comprises about a quarter of total global power-generating capacity and supplies close to 20% of global electricity, with most of this provided by hydropower.
Developing countries (collectively) have more than half of global renewable energy power.
And so on. Quite encouraging, really.
More news on renewables
A new analysis by the California Institute of Technology (Caltech) finds that the power output of wind farms can be increased tenfold — and with fewer environmental impacts — through better positioning of vertical-axis turbines.
A novel application of carbon nanotubes, developed by MIT researchers, shows promise as an innovative approach to storing solar energy for use whenever it’s needed.
Petratherm… has just completed fracture stimulation tests that indicate its resource in the north of South Australia is deeper, wider and hotter than it previously thought.
They think they can get three rather than two production wells for every injection well.
New clean energy investment ticked up strongly last quarter, data released by Bloomberg New Energy Finance last week showed.
For the April-June period, new capital invested into the sector rose 22 per cent over the year earlier period to reach a robust $US41.7 billion.
meaning that it overtakes the US as the biggest solar generator in the world. The nation’s total solar power production is now equivalent to the output of a nuclear power station.
New Scientist has an article on leaking methane in the US. Robert Howarth of Cornell University:
has calculated that 2.2 to 3.8 per cent of shale gas leaks out at the well site and an additional 1.4 to 3.6 per cent leaks during transport, storage and distribution – enough to make shale gas a bigger contributor to global warming than coal. (Emphasis added)
There is still a great deal of uncertainty, which needs to be resolved to establish the total carbon implications of gas-generated power.
Why economists support carbon pricing
John Quiggin tells us why virtually all economists support a carbon price. I can’t summarise his arguments briefly, so go read. He does say this about its impact:
It follows that, although the carbon tax will have a significant impact on our aggregate emissions of CO2, mainly through its impact on electricity generation and energy use by business, the average household will barely notice it. This was true of the GST, which takes about $40 billion a year in revenue, and it will be just as true of the carbon tax at a quarter the size. (Emphasis added)
News on carbon pricing
Climate Progress was more than pleased with Australia’s new package.
Gillard has established Australia, the highest per capita carbon emitting country in the developed world, as a much needed international leader in the effort to address climate change.
Modest in its ambition but exemplary in its efficacy, they say. Also not a bad photo of the PM, I thought.
The South Korean cabinet has approved a plan to cut carbon emissions 30% below expected levels in 2020. In support of this, the government has submitted a bill to parliament that includes plans for an ETS from 1st January 2015.
The plan is to hold emissions close to steady while the economy grows. It includes transport and CCS.
Then there is China:
China will introduce a pilot scheme for carbon emissions trading and gradually develop a national market as the world’s largest polluter seeks to reduce emissions and save energy, state media said.
China will promote the market’s development through ‘punitive’ electricity tariffs on power-intensive industries and other new policies, Xie Zhenhua, a top climate official, was quoted by Xinhua news agency as saying.
Republicans support fossil fuels
The US Republicans are being extremely vigorous in their full-on support for fossil fuels. Measures they have voted for include prohibiting spending to enforce the incandescent lighting efficiency standards in the 2007 energy law signed by President George W. Bush and nullifying Section 526, which prevents the federal government from buying high-carbon fuels like tar sands oil or coal-to-liquids. Even they were not silly enough to approve am amendment prohibiting federal websites that teach children about energy efficiency but they seem intent in getting stuck into research and other initiatives likely to combat climate change.
More here. Presumably Obama doesn’t sign off on this stuff, but I guess it might indicate what is on the table as he negotiates the US debt extension.
