WASHINGTON — Earth is likely to hit more dangerous levels of warming even sooner if the U.S. pulls back from its pledge to cut carbon dioxide pollution, scientists said. Other global leaders have been urging him to stay during high level security and economic meetings in Italy that began Friday. "If we lag, the noose tightens," said Princeton University climate scientist Michael Oppenheimer, co-editor of the peer-reviewed journal Climatic Change. It found that America would add as much as half a degree of warming (0.3 degrees Celsius) to the globe by the end of century. Another computer simulation team put the effect of the U.S. pulling out somewhere between 0.1 to 0.2 degrees Celsius.
