Coal Miners, Eastern India, 1998

Photo: Coal Miners
"Turning the planet inside out, miners 260 feet (80 meters) down in eastern India dig coal that will release carbon dioxide (CO2) into the atmosphere when burned. As emerging nations join their industrialized neighbors in burning more fossil fuels, the amount of CO2 in the air is expected to double in the next century. Most experts, acknowledging the awesome complexity of Earth's climate system, believe higher CO2 levels carry a real threat of raising global temperatures and bringing about significant climate change."

—From "Unlocking the Climate Puzzle," May 1998, National Geographic magazine
