Changes in ocean chemistry and temperature have had a dramatic effect on the diversity of corals and sea anemones, according to a team of scientists who have traced their evolution through deep time.

Ice sheets in Greenland and Antarctica whose melting rates are rapidly increasing have raised global sea level by 1.8cm since the 1990s, and are matching worst-case climate warming scenarios.
