ANU's Brendan Mackey has release a new paper “Green Carbon - The role of natu ral forests in carbon storage” that furthers previous work at the ANU ion the critical role native forest play in storing large amounts of carbon.

The report also make this critical comment on the ultimate goal for climate change:

“What constitutes a ‘safe level’ is a critical question that is being debated actively among scientists and policy advisors. Evidence from glacial ice cores has revealed that atmospheric concentrations of carbon dioxide ranged between 180 and 300 parts per million by volume (ppmv) in the past 650 000 years (with typical maximum values of 290 ppmv) (Petit et al. 1999; IPCC 2007). Assuming this natural variability revealed by the ice-core records persisted, we should assume a maximum safe level is 300 ppmv.”

The paper is available from the ANU website.

The Zero Emission Network has looked at the previous work on this issue and has discussed the matter in our The paper is available from the ANU website.”>facts and figure section. We look forward to updating this page.
