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 ...
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...
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

The sea is Earth's most formidable carbon dioxide storage machine, but mysteries abound about the interlocking processes and the myriad organisms involved.Now, thanks to NSF-funded research published ...
Salt marshes' capacity to store carbon may be threatened by nitrogen pollution（图）
Salt marshes capacity carbon nitrogen pollution
2019/10/18
Deep in the waterlogged peat of salt marshes, carbon is stored at much greater rates than in land ecosystems, serving as an offset to climate change caused by carbon dioxide (CO2) build-up in the atmo...

Scientists long-standing mystery atmospheric carbon dioxide lower during ice ages
2019/10/28
Since scientists first determined that atmospheric carbon dioxide was lower during ice ages than during warm phases, they have looked at why, theorizing that it may be a function of ocean circulation,...
