Rocks Found That Could Store Greenhouse Gas

Geologists have mapped 6,000 miles of large rock formations in the United States that could be used to store some of the excess carbon dioxide building up in Earth’s atmosphere.

The carbon dioxide released by fossil fuel burning has been continually accumulating in the atmosphere since the start of the Industrial Revolution. While some of the greenhouse gas is taken up by plants and absorbed by the ocean, a significant amount is still hanging out in the air, trapping some of the heat that Earth's surface would otherwise radiate to space and thereby warming the globe….more at LiveScience
