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...
Turning carbon emissions into rocks（图）

2023/7/7
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....
Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Reevaluation of the carbon emissions embodied in global value chains based on an inter-country input-output model with multinational enterprises
跨国企业 国家间 投入产出模式 全球价值链 碳排放
2023/5/9
Multinational enterprises actively participate in global production networks. However, the current global value chain accounting framework fails to consider the emissions originating from the producti...

“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.
Losses of eelgrass beds give rise to large emissions of carbon and nutrients
eelgrass bed ecosystem eutrophication nitrogen
2021/8/5
Losses of important eelgrass meadows in western Sweden since the 1980s have led to considerable bottom erosion and the release of carbon and nitrogen; substances that contribute to increasing climate ...
California's carbon mitigation efforts may be thwarted by climate change itself
climate change carbon mitigation ecosystem
2021/8/3
To meet an ambitious goal of carbon neutrality by 2045, California's policymakers are relying in part on forests and shrublands to remove CO2 from the atmosphere, but researchers warn that future clim...
Extraordinary carbon emissions from El Nino-induced biomass burning estimated
El Nino carbon emission carbon dioxide
2021/8/3
In 2015, massive biomass burning events occurred in Equatorial Asia which released a large amount of carbon into the atmosphere, whose signals were captured by in-situ high-precision measurements onbo...
Coastal ecosystems worldwide: Billion-dollar carbon reservoirs
ecosystem change climate change carbon storage ecosystem
2021/8/5
Australia's coastal ecosystems alone save the rest of the world costs of around 23 billion US dollar a year by absorbing CO2 from the atmosphere. Coastal ecosystems such as seagrass meadows, salt mars...
