Instead, the Cancun talks, waiting for another day, focused on small steps on climate: some advances in establishing a system to compensate developing nations for protecting their forests, for example, and in setting up a global clearinghouse for "green" technology for developing nations. Cancun's chief accomplishment was to decide to create, with details to come, a Green Climate Fund that will handle those expected tens of billions of dollars in climate support. This slowly-slowly approach began at the climate summit in Copenhagen, Denmark, last year, when the U.S., China, other big emitters and some small one pledged to carry out voluntary reductions in emissions. Some say this will be the way global warming will be addressed, not with "top-down," legally binding treaties, but with self-assigned targets, bilateral deals to help create low-carbon economies, aspirational goals set by G-20 summits. If the world busies itself with such voluntary activities, this thinking goes, it may all add up to climate protection. But scientists do numbers better than politicians. And the latest U.N. scientific calculation shows that the current emissions-reduction pledges, even if all are fulfilled, will barely get the world halfway to keeping temperatures rising to dangerous levels. The U.S. pledge
-- based on executive, not congressional action -- is for a mere 3 percent reduction of emissions below 1990 levels. If too little is done, the U.N. science network foresees temperatures rising by up to 6.4 degrees Celsius (11.5 degrees F) by 2100. In a timely reminder of what's at stake, NASA reported last week that the January-November 2010 period was the warmest globally in the 131-year record. At that rate, climate will become the elephant no one can ignore.
