Climate change: life in ocean ‘twilight zone' at risk from warming

BBC News Climate & Science

Global warming could curtail life in the so-called twilight zone by as much as 40% by the end of the century, according to new research.It teams with life but was home to fewer organisms during warmer periods of Earth's history, researchers found. They found far fewer organisms lived in the zone during these periods, because bacteria degraded food more quickly, meaning less of it reached the twilight zone from the surface.

The twilight zone, also known as the disphotic zone, is a vital habitat for marine life. It is too dim for photosynthesis to occur but home to more fish than the rest of the ocean put together, as well as a wide range of life including microbes, plankton and jelliesIt also serves a key environmental function as a carbon sink - drawing planet-heating gas out of our atmosphere.
