Science Low Salt Marsh Habitats Release More Carbon in Response to Warming, a New Study Finds This complicates their role as carbon sinks as temperatures, and the sea level rises.

"Salt marshes are far more persistent carbon sinks than forests or other terrestrial sites," says Brian Yellen, Massachusetts's state geologist, research assistant professor at UMass Amherst and ...

Maine salt marshes are a key tool in the fight against climate change, acting as a buffer against storms and soaking up planet-warming emissions. These reservoirs of "blue carbon" can be 10 times ...

“Salt marshes are far more persistent carbon sinks than forests or other terrestrial sites,” said Brian Yellen, Massachusetts ...

Salt marshes' capacity to sink carbon may be threatened by nitrogen pollution. Aug 26, 2019. High carbon dioxide can create 'shrinking stems' in marshes. Sep 25, 2019.

So far, her data suggest that at least over the next 20 years, salt marshes should remain carbon sinks. But as climate change progresses, they won’t be able to offset as much carbon as they do now.

A healthy marsh is one of the most effective carbon sinks on the planet, Johnson said. “Salt marshes are such beautiful, special places, but we are losing them fast,” Johnson said while ...

Salt marsh loss resulted in 16.3 teragrams, or 16.3 million metric tons, of carbon emissions per year, according to the study. That’s the rough equivalent of the output of around 3.5 million cars.

“Salt marshes are far more persistent carbon sinks than forests or other terrestrial sites,” says Brian Yellen, Massachusetts’s state geologist, research assistant professor at UMass Amherst ...

Scientists project that Maine could lose 28-57% of its salt marshes by the end of the century — victims of rising seas, coastal development and polluted runoff, with consequences for ...
