I do not deny the physics of Greenhouse gasses, they are inarguable and unalarming. Doubling the atmospheric level of CO2 will increase the temperature by approximately one degree C. The 'crisis' of CO2 is due to the speculations about further feedbacks. So far the observational support for these further feedbacks does not match the models.
The figures I use above about what Australia has achieved are based on the published figures of Australia producing 1.5 percent of Global CO2, and reducing our increase by 108% instead of 110% of our 1990 GDP, and having signed the Kyoto protocol in 2007.
xyz's graph is impressive, but doesn’t take into account that global temperature was rising at the same rate naturally, for centuries before his start date, before the industrial revolution. It answers Stand for Christ effectively, but doesn’t show what he thinks it does.

The figures for the melting of the Greenland icecap vary from 2000 to 13000 years. I believe we have more immediate problems to address.
