Nature.com: Ocean greenery under warming stress
Phytoplankton, the microscopic marine plants which are the basis of all marine ecosystems, have been declining for more than 100 years, perhaps the result of rising sea temperatures, according to a study published in this week’s Nature. The researchers found that phytoplankton is declining in 8 out of the 10 oceans at an average rate of 1% per year, a fall that could have significant impacts on the marine food chain and the world’s carbon cycle.
