Copenhagen Accord Summary Sudarshan Balakrishnan 15th conference of the United Nations Framework met 7-19, 2009 in Copenhagen Signed a pact called the Copenhagen Accord. All but a few countries( Bolivia, Cuba etc) supported it. 2ºC warning limit is much more efficient than a 50 -80 % reduction in (CO) 2 emissions before 2100. The 2ºC barrier is based on recommendations and failure to comply with will lead to climate tipping elements. Climate should warm by .8ºC/watts/sq.meter Radiant energy can hence not increase/exceed 2.5 W/m 2 2ºC is equivalent to 2.5 W/m 2 is equivalent to 1280 terawatts summed over earth. Energy budget criteria equivalent (CO 2 ) equivalent to rise to the 2.5 W/m 2 . Analytic equation is given by H’ = H o ln[ (CO 2,e )/ (CO 2,ref )] (CO 2,ref ) of preindustrial era is equivalent to 280 ppm , H’ = 2.5 W/m 2 is equivalent to 441 ppm before 2100. 2.5 W/m 2 has already been exceeded by 20%. Air pollution laws must enforce offsetting reduction in Black Carbon and ozone to remain energy neutral. Avenues Stabilize below 441 ppm. Offset the addition of radiant energy and reduce the Black carbon and ozone concentration Thin the Green House Gas blanket Challenges Reduction of long lived GHG’s such as CO
