In a hard-hitting speech, former Australoian Prime Minister, Tony Abbott has called on his country to follow the United States in pulling out of the Paris Climate Accord. "Knowing what we know now, we would not have made the Paris agreement. But if we wouldn’t have done it, had we known; we shouldn’t be in it, now that we do." (The late Professor Robert Carter, at whose Commemorative Lecture Mr Abbott spoke, was a founding member of our Coalition).
