Lessons from the past: How cold-water corals respond to global warming

Corals react to changes in their environment. This is true for tropical as well as cold-water corals and includes, among others, changes in temperature, salinity and pH values. Researchers have now investigated how warmer temperatures occurring as a result of climate change are affecting cold-water corals. For this purpose, they examined in detail how these corals have reacted to environmental changes over the past 20,000 years.
