Corals may store a surprising amount of microplastics in their skeletons

In tropical waters, coral reefs may be a “sink” for tiny bits of plastic debris. It’s unclear how corals’ trash pickup might affect reef health.

Albatrosses divorce more often when ocean waters warm

In one part of the Falkland Islands, up to 8 percent of the famously faithful birds ditch partners in years when the ocean is warmer than average.
