Poor countries join the rich in agreeing to monitor emissions

Delegates from 193 nations meeting in Cancun, Mexico, early Saturday adopted a modest climate deal, pledging that both developed and poorer nations will curb emissions in an effort to limit average increases in the world's temperature to 3.6 degrees Fahrenheit by the end of the century. The U.S. and Europe insisted that developing nations be required to report their progress on cutting emissions for fear China might try to hide its results.
