Dr Andrew Glikson et al, part of a joint statement prepared with Dr Barrie Pittock PSM (former leader, Climate Impact Group, CSIRO, IPCC Lead Author), and endorsed by 40 leading Australian environment scientists: “Australia to make every effort through its own and international actions to prevent CO2 -- equivalent levels from rising above 450 ppm and global warming from rising above 2 degrees C relative to pre-industrial temperatures, as is the European target. Further reduction of CO2 levels to 300-350 ppm may be required to have a reasonable probability of restoring a safe climate.” [1].
