4 Degrees or more? - Science into Policy: Securing a Clean Energy Future for Australia - speech by Greg Combet

In an early morning session on Thursday the Minister for Climate Change and Energy Efficiency, Greg Combet, addressed the Four degrees or more? conference and spoke on the scientific imperatives driving the Government to price carbon and outlined the Government's carbon pricing policy and addressed some of the consequences of that policy for science and innovation.

Despite the policy failing to match the emissions reductions that are needed to close the Global Emissions Gap to limit temperatures to 1.5 to 2 degrees Celsius of global warming, most of those present saw the policy as necessary first steps and were impressed with the multifaceted comprehensive features which will help to decarbonise the economy and drive innovation towards clean energy to adapt to the impacts of climate change.

Here is a transcript of his full speech.

4 Degrees or More? Climate Change: The Critical Decade - a speech by Professor Hans Joachim Schellnhuber

This was the 1st keynote address to the Four degrees or more? conference Australia in a hot world which is currently meeting in Melbourne. After a day and a half of listening to climate scientists detailing the present climate impacts and future projections, understandably I, and many others, felt a little depressed.

But most of these scientists and other delegates are possessed of a human optimism that the challenge can be overcome. That human society has the technical and engineering capability to avoiding a 4 degree or higher world, to limit global warming to 2 degrees celsius as agreed to in Copenhagen in 2009 and affirmed in Cancun in 2010.

Australian Carbon pricing policy a small start to tackling climate change

On Sunday the Gillard Federal Government announced it's carbon tax at $23 a tonne of carbon to be imposed on the 500 largest carbon polluting companies starting from July 1st, 2012. More than half the money raised will be returned to low and middle income earners, pensioners and retirees as compensation. Additional packages include $10 billion renewable energy and low emissions technology fund, substantial assistance packages to 'trade exposed' industries, $1.9 billion to fund carbon geo-sequestration in the land sector, and a $1 billion biodiversity fund.

The initial rate of $23 a tonne will be indexed at 2.5% for 3 years before an Emissions Trading Scheme is introduced in 2015 with a cap and floor price set by the Government. An independent Climate Change Authority will be established to recommend targets when the emissions trading scheme commences to take some of the politics out of the process. A target of 80% emissions reduction from 2000 levels by 2050 will be set.

Carbon price in a nutshell according to the Australian Youth Climate Coalition (AYCC)

Australian Prime Minister Julia Guillard announced the major details of the carbon price (carbon tax) at midday today flanked by Climate Change Minister Greg Combet and Treasurer Wayne Swan. The package entails substantial compensation to middle and low income households, taxpayers, pensioners and self funded retirees. It also establishes a $10billion renewable energy fund. More on the details and responses later. Here is a short video from the Australian Youth Climate Coalition explaining the policy in a nutshell.

"Using the latest in Power Point technology, the AYCC communications team has been up all night preparing this short explanation of how the Gillard Government’s announced carbon price will work." explained Glen in posting this video on the AYCC website.

Scientist: Less rain across southern Australia a long term climate trend

Increasing atmospheric carbon dioxide concentrations is increasing atmospheric temperatures changing the dynamic of the sub-tropical jet stream and thus the number and intensity of storms bringing autumn and winter rainfall to southern Australia, according to CSIRO climate scientist Dr Jorgen Frederiksen. He was addressing the International Union of Geodesy and Geophysics conference in Melbourne this week regarding recent research on changes to atmospheric circulation, storm intensity and reduction in winter rainfall in Australia.

Warming Arctic air temperatures causing less snow, more rain, faster ice melt

Arctic air temperatures are warming faster than anywhere else on Earth. Although the level of precipitation is remaining unchanged, there is reduced snowfall in summer which is being replaced by increasing rain. The loss of summer snow and increase in rain is resulting in a positive feedback mechanism increasing warming and melting of the Arctic ice.

We are already witnessing an increase in the Albedo feedback mechanism - loss of reflectivity in the arctic leading to more warming and greater ice melt. Research published early in 2011 revealed Loss of reflectivity in the Arctic is double the estimate used in climate models. With the change in precipitation we have a further feedback mechanism contributing to Arctic warming and melting of snow and sea ice.

'The carbon tax' launches on Sunday - satire by Clarke and Dawe

Some satirical commentary by comedians John Clarke and Brian Dawe on the launch of the Carbon tax for Australia. Originally aired on The 7.30 Report on Thursday July 7, 2011.

The US 'normal climate' just got hotter

For the USA the 'normal climate' just got warmer. Every decade the National Oceanic and Atmospheric Administration (NOAA) updates a range of climate measures averaged over the previous 30 years. These measures are called the climate normals.

From July 2011 the latest climate normals will be for the 30 years from 1981 to 2010. Climate measures for the 1970s has been dropped and the first decade of the 21st century, the hottest on record has been added. This has resulted in both maximum temperatures and minimum temperatures being about 0.5F warmer on average in the new normals. "The climate of the 2000s is about 1.5 degree F warmer than the 1970s, so we would expect the updated 30-year normals to be warmer,” said Thomas R. Karl, L.H.D., National Climate Data Centre director.

Tony Abbott arguing for a carbon tax in 2009

This is Tony Abbott in 2009, denying climate change, arguing against the 'complex' CPRS scheme and arguing for a 'simple carbon tax'. At least former leader Malcolm Turnbull was approaching climate change action in a bipartisan way. Abbott doesn't even have the intellectual rigour to appreciate climate science and the impacts already being felt in a warming world.

Victorian Government needs to come clean on plan to achieve 20 percent emissions cut by 2020

On July 1st 2011 the Victorian Climate Change Act became law. It was passed last year with bipartisan support. The Act sets into law that Victoria will cut the state's emissions by 20 per cent by 2020 based on year 2000 emissions baseline and empowers the Environment Protection Authority to regulate emissions from industry.
