Warming Fix

FILE - In this June 25, 2007 file photo, a gas well recovering methane gas at a landfill in Ferris, Texas. An international team of scientists say they've figured out how to slow global warming in the short run, prevent millions of deaths from dirty air and increase food production. And it will save more money than it will cost. They say the key is to reduce emissions of two other greenhouse gases instead of carbon dioxide. Those pollutants are methane and soot. Those powerful gases are fast acting so reducing them would pay off quickly. Soot also is a big health problem, so cutting it would save lives. (AP Photo/Donna McWilliam, File)
