Farmers may pay a stiff price for contributions to global warming. - Tucson Citizen- About: global warming news

Ron Sparks, a Democrat who is Alabama's agriculture commissioner and president of the National Association of State Departments of Agriculture, says the fees would drive livestock farmers out of business. The Supreme Court ordered the Bush administration to declare whether greenhouse gas emissions harm the public, and if so to regulate them as a dangerous pollutant. But USDA says that using the Clean Air Act to control greenhouse gases would trigger regulations on farms under rules that require businesses to obtain permits to emit more than 100 tons of a pollutant in a year. Farmers with as few as 200 hogs or 50 beef cattle or 25 dairy cattle would hit the 100-ton threshold, according to a five-page USDA document assessing the impact using the Clean Air Act to regulate emissions.
