PITTOCK, BARRIE. Dr Barrie Pittock et al : reduction of CO2 levels to 300-350 ppm may be required

Dr Barrie Pittock led the Climate Impact Group in CSIRO until his retirement in 1999. He contributed to or was a lead author of all four major reports of the Intergovernmental Panel on Climate Change. He was awarded a Public Service Medal in 1999 and is a CSIRO Honorary Fellow. He is author of “Climate Change. The Science, Impacts and Solutions” (see: http://www.publish.csiro.au/pid/6010.htm. ).

Dr Barrie Pittock et al, part of a joint statement prepared by Dr Barrie Pittock PSM (former leader, Climate Impact Group, CSIRO, IPCC Lead Author, and author of Climate Change: Turning Up the Heat), and Dr Andrew Glikson (Earth and paleoclimate research scientist, former Principal Research Scientist, AGSO; Visiting Fellow, Australian National University), 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].
