U.N. talks on a new climate pact resumed Monday in oil and gas-rich Qatar, where negotiators from nearly 200 countries will discuss fighting global warming and helping poor nations adapt to it. The two-decade-old talks have not fulfilled their main purpose: reducing the greenhouse gas emissions that scientists say are warming the planet. (AP Photo/Osama Faisal)
