January 17, 2018 — Sea grasses are part of a team of coastal vegetation, including mangroves and salt marshes, that store up to 100 times more carbon than tropical forests at 12 times the speed. Vast prairies of sea grasses stretch for kilometers along the seafloor, storing enough carbon to rival the world’s forests.

January 4, 2018 — Ocean dead zones with zero oxygen have quadrupled in size since 1950, scientists have warned, while the number of very low oxygen sites near coasts have multiplied tenfold.

Mass coral reef bleaching events have become five times more common worldwide over the past 40 years, new research finds, with climate change playing a significant role in the rise
January 4, 2018 — The scale of bleaching has been rising steadily in the last four decades, a study author tells Carbon Brief, with the global proportion of coral being hit by bleaching per year rising from 8% in the 1980s to 31% in 2016.
