Science critical to climate change action

A leading soil scientist is urging governments to listen to the experts on climate change, and act now.

Dr Ian Porter is an advisor on the Montreal Protocol - the panel that has successfully tackled the hole in the ozone layer.

Dr Porter says scientific advice has been crucial to healing the ozone, and in beginning the work on climate change.

"Now under the Montreal Protocol, the HCFCs are being regulated for phase out and that work has done six times more than the first commitment period of Kyoto will do," he says.

"So there's been a real benefit of the Montreal Protocol, not just for ozone depletion, but also for climate change."
