Researchers find that the global carbon pool in seagrass beds is as much as 19.9B metric tons

Green Car Congress

Per unit area, seagrass meadows can store up to twice as much carbon as the world’s temperate and tropical forests, according to a paper this week in the journal Nature Geoscience. The paper, “Seagrass Ecosystems as a Globally Significant Carbon Stock,” is the first global analysis of carbon stored in seagrasses.

IPCC Scientist Says Climate Change Likely to Accelerate More Quickly and Be More Damaging Than Predicted

Green Car Congress

There is a real risk that human-caused climate change will accelerate the release of carbon dioxide from forest and tundra ecosystems, which have been storing a lot of carbon for thousands of years. We don’t want to cross a critical threshold where this massive release of carbon starts to run on autopilot. Chris Field.

Study Finds East Siberian Arctic Shelf Showing Instability and Widespread Venting of the GHG Methane; Releases May Be Much Larger and Faster Than Anticipated

Green Car Congress

Methane is a greenhouse gas more than 30 times more potent than carbon dioxide. These findings do change our view of the vulnerability of the large sub-sea permafrost carbon reservoir on the ESAS; the permafrost “lid” is clearly perforated, and sedimentary CH 4 is escaping to the atmosphere. The permafrost under the ESAS—a 2.1
