Deep Seagrass Bed Could Stall Climate Change, If Climate Change Doesn’t Kill It First

Researchers studied the carbon storage of deep-water seagrasses living at Lizard Island, Australia.

Amid a sea of dire climate change news, researchers say they’ve found a rare bright spot.

A meadow of seagrass among Australia’s Great Barrier Reef — estimated to be twice the size of New Jersey — is soaking up and storing carbon that would otherwise contribute to global warming.

Scientists call this carbon-removal powerhouse a “blue carbon sink.” The term refers to an ocean or coastal ecosystem — including seagrasses, salt marshes and mangrove forests — that captures carbon compounds from the atmosphere, effectively removing carbon dioxide, a known greenhouse gas that contributes to climate change.
