CLIMATE CHANGE: Coal miner Scott Tiller eats a sandwich during his lunch break in a mine less than 40-inches high in Welch, W.Va. For over a century, life in Central Appalachia has been largely defined by the ups and downs of the coal industry. There is a growing sense in these mountains that for a variety of reasons - economic, environmental, political - coal mining will not rebound this time. The slump is largely the result of cheap natural gas, and older coal-fired power plants being idled to meet clean-air standards. According to the Labor Department, there were 56,700 jobs in coal mining in March, down from 84,600 in March 2009, shortly after President Barack Obama entered office. "I have four grandchildren who are going to have to have some kind of a future," said Tiller. "I don't want them being coal miners. It's a hard, tough way to make it and I just don't want that for them." (AP Photo/David Goldman)
