Scientists to map out earth`s soil
Some of the answers to the world’s greatest challenges -- such as climate change, food security, and water scarcity -- lie right beneath our feet. Responding to these and other critical issues, a group of scientists from around the world have announced an ambitious new plan to digitally map the Earth’s soil and its properties. Scientists, industry leaders, and government officials gathered at Columbia University to launch GlobalSoilMap.net, a pioneering new tool that will shape future policy making, especially in those regions of the world most vulnerable to environmental shocks.

Geologists map rocks to soak CO2 from air
To slow global warming, scientists are exploring ways to pull carbon dioxide from the air and safely lock it away. Trees already do this naturally through photosynthesis; now, in a new report, geologists have mapped large rock formations in the United States that can also absorb CO2, which they say might be artificially harnessed to do the task at a vastly increased pace. The report, by scientists at Columbia University’s Earth Institute and the U.S. Geological Survey, shows 6,000 square miles of ultramafic rocks at or near the surface. Originating deep in the earth, these rocks contain minerals ... |
