My question is to the Minister for the Environment and Heritage, Senator Ian Campbell. Does the government agree with leading scientists that we have a window of only 10 to 15 years—that is until approximately 2020—to take steps to avoid crossing a catastrophic climate tipping point beyond which we have little hope of stabilising greenhouse gas emissions below 550 parts per million, a level already associated with significant risk?
