Urgency of Climate Talks Seen in Coal Plants, Ice by Associated Press WARSAW, POLAND -- As politicians haggle at a U.N. climate conference in Poland over ways to limit global warming, the industries and machines powering our modern world keep spewing their pollution into the air and water. The fossil fuels extracted from beneath the Earth's crust -- coal, oil and gas -- are transformed into the carbon dioxide that is now heating the planet faster than scientists had expected even a few years ago. The devastating wildfires, droughts, floods and hurricanes of recent months and years are intensifying the urgency of the two-week conference in Katowice, which is due to end Friday. But not far from the conference center, plumes of smoke rise from Europe's largest lignite, or brown coal, power plant, in the central Polish town of Belchatow. Of the 50 most polluted cities in the European Union, 36 are in Poland. IN PHOTOS: The Urgency of Climate Talks
