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....
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.
Carbon dioxide levels are rising across wide swaths of the Arctic Ocean's Canada Basin（图）
Carbon dioxide levels rising across wide swaths Arctic Ocean Canada Basin

Cold Climates Ocean Carbon Sequestration
2017/3/30
We know a lot about how carbon dioxide (CO2) levels can drive climate change, but how about the way that climate change can cause fluctuations in CO2 levels? New research from an international te...
Earlier snowmelt decreases streamflow,reduces forests'ability to regulate atmospheric carbon dioxide
snowmelt decreases streamflow reduces forests'ability atmospheric carbon dioxide
2016/8/11
Earlier annual snowmelt periods may hinder the ability of forests to regulate atmospheric carbon dioxide (CO2), according to the results of a new study.The findings, published in Geophysical Research ...
