World leaders have been meeting for 29 years to try to curb global warming, and in that time Earth has become a much hotter and deadlier planet. Trillions of tons of ice have disappeared over that period, the burning of fossil fuels has spewed billions of tons of heat-trapping gases into the air, and hundreds of thousands of people have died from heat and other weather disasters stoked by climate change, statistics show. World leaders have hammered out two agreements to curb climate change. In Kyoto in 1997, a protocol set carbon pollution cuts for developed countries but not poorer nations. That did not go into effect until 2005 because of ratification requirements. In 2015, the Paris agreement made every nation set its own emission goals. In both cases, the United States, a top-polluting country, helped negotiate the deals but later pulled out of the process when a Republican president took office.
