The leaves of trees and plants have been called the Earth’s lungs because they take in carbon dioxide and give out oxygen. But beneath the soil’s surface, the roots of those plants are doing their bit...
In a first-of-its-kind analysis, Cornell researchers and partners at the Clinton Health Access Initiative found that pharmaceutical producers could reduce their environmental impact by roughly half by...
As carbon dioxide continues to build up in the Earth’s atmosphere, research teams around the world have spent years seeking ways to remove the gas efficiently from the air. Meanwhile, the world’s numb...

Chemist Peter Psarras has good reason to call himself a musical rock star—after all, he plays bass and keyboard semi-professionally—but he’s more likely to claim “rock” stardom of the geological bent....

“Tuck your pants into your socks – the ticks can be really bad out here,” graduate student Dave Frey tells the group of four students as they embark from their cars.
Reaching carbon emission goals requires efforts on all fronts of carbon management: decreasing carbon emissions, capturing carbon, and storing carbon.
The U.N.’s Intergovernmental Panel on Climate Change suggested in a recent report that with every degree of warming, global agricultural production will be reduced by 10 to 25 percent, threatening the...
If researchers could find a way to chemically convert carbon dioxide into fuels or other products, they might make a major dent in greenhouse gas emissions.

Engineering Mississippi River kept carbon out atmosphere
2021/4/9
A new study co-authored by a Tulane University geoscientist shows that human efforts to tame the Mississippi River may have had an unintended positive effect: more rapid transport of carbon ...
Much of the carbon in space is believed to exist in the form of large molecules called polycyclic aromatic hydrocarbons, or PAHs. Since the 1980s, evidence has indicated that these molecules are abund...
As humans continue to send large quantities of carbon into the atmosphere, much of that carbon is absorbed by the oceans. Now researchers from the University of Connecticut and other institu...
