Most observers judged as a failure the December meeting in Copenhagen of the Conference of Parties of the UN Framework Convention on Climate Change (UNFCCC). But then the usual way of judging such meetings is to look for a communiqué that voices sweeping aspirations, such as the G-7 “decision” at L’Aquila last summer to limit global warming to 2 degrees centigrade. In reality, without any evidence of countries agreeing what is each one’s share of the burden, such proclamations are worthless. Better tiny steps on the ground than giant flights of rhetoric.
