  1. February 4, 2010. With January 31st as the 'soft' deadline for countries to submit to the UNFCCC their proposals for greenhouse gas emissions reductions under the Copenhagen Accord we've been hearing the question from colleagues and the press: do these submissions bring the world any closer to the goal of limiting temperature increase to 1.5° or 2°C? We've 'run the numbers' and our most recent analysis shows essentially the same results that we reported December 19th at the close of the Copenhagen Summit: if current proposals were fully implemented average global temperature would overshot the 2° goal and would in fact increase by approximately 3.9°C (7.0°F) by 2100.
