'A greener green and a bluer blue': How global warming is changing the color of the ocean

At a time when global warming is intensifying and scientists are collectively observing the failure of global policy measures to rapidly address this threat, extreme events continue to multiply. On land and at sea, no ecosystem is immune to the ravages of a world in turmoil. From space, satellites are observing the metamorphosis of the Earth , which, in just a few decades, has acquired a green mantle. This is the central finding of a study published this Thursday, June 19, in the journal Science by four scientists affiliated with American universities. Using satellite imagery, they analyzed the concentration of chlorophyll in the ocean.
