Researchers analyzed dissolved organic carbon from water column samples collected in five regions to establish baseline data about its relative persistence and cycling in the northern Gulf of Mexico. The team found that the Mississippi River exports large amounts of dissolved organic carbon with an anthropogenic 14C signature, which is removed and recycled offshore as the river plume moves offshore.
Global fisheries output will slump by 20 percent by 2300 and by 60 percent in the worst-hit North Atlantic region if governments fail to slow long-term global warming, a U.S. team of scientists said on Thursday.
Scientists on Tuesday published new evidence that old or even ancient carbon, pulled out of the atmosphere and stored in the bodies of plants hundreds or thousands of years ago, is being set loose again from soils in the Arctic region.
The Paris Agreement highlights the need for local climate leadership. The University Of California’s approach to deep decarbonization offers lessons in efficiency, alternative fuels and electrification. Bending the emissions curve globally requires efforts that blend academic insights with practical solutions.
