Professor David Karoly from University of Melbourne presented an update on the science of climate change at the annual Australian Geothermal Energy Conference in Adelaide in November 2010. Click on talk to see the presentation. In particular see slide number 16 which shows that Australia needs to reduce its CO2 emissions by 25-40% by 2020 and 90-97% by 2050 for its fair share of emissions in order to have a 50-50 chance of avoiding 2 degrees of warming. At the December 2010 Cancun climate conferenced most countries of the world committed to the 2 degree limit.
