In Face Of Tiny GHG Cuts Under Rudd Plan, Scientists Call For "A Bit Of Scientific Honesty"

[hatrack]

SOME climate scientists have turned on the Federal Government, calling for "scientific honesty" after it delivered its target range for emissions cuts of between 5 and 15 per cent yesterday. The mainstream scientific community believes much deeper cuts are needed more quickly and that yesterday's announcement all but locks Australia into a hot and rather bleak future.

The modest cuts for 2020 are seen as marking a fork in the road in Australia's approach to climate change, with the Government proceeding down one route and the research that underpins the need for emissions cuts heading down another.

"There's now a disconnect between what politicians are doing and what the science requires," Professor Barry Brook, director of the Research Institute for Climate Change and Sustainability at the University of Adelaide, said. "Targets in that range <5 to 15 per cent> are politically realistic but not scientifically realistic. "Just talking about emissions cuts at these small levels is avoiding the main point, which is that we're already over the limit. Let's have a bit of scientific honesty in the debate."

EDIT

Carbon cuts from 25 to 40 per cent on 1990 levels are required by 2020, along with an international agreement that ties major polluting nations to similar cutbacks, are needed to ward off the worst effects of climate change, according to the Government's Garnaut climate change review. That report concluded that allowing the concentration of greenhouse gases in the atmosphere to rise to 550 parts per million, which is what the Government's cuts will mean if other nations make similar modest moves, would be disastrous for Australia. It would mean the disappearance of the Great Barrier Reef "as we know it, with high impact to reef-based tourism", collapsing biodiversity in many districts, major changes to the tropics and Kakadu National Park and a cut of 20 per cent to food production along the Murray-Darling system.
