Twenty years of research has led Dr. Graham Jones of Australia’s Southern Cross University to discover a startling connection between coral reefs and coastal precipitation. According to Jones, a substance produced by thriving coral reefs seed clouds leading to precipitation in a long-standing natural process that is coming under threat due to climate change.

“Coral reefs produce a volatile substance called dimethylsulphide or DMS which oxidizes in the atmosphere to produce cloud condensation nuclei (CCN). These are tiny sulphur aerosol particles around which water vapor condenses to form clouds,” Jones explained to mongabay.com, adding that, “water vapor cannot form clouds without these tiny aerosol particles being present.”

Yet, in his studies, Jones has discovered that even a slight rise in ocean temperatures could affect this natural process, making climate change a significant threat to clouds (and precipitation) seeded by coral reefs.

Jones says that the Australian government has a number of policies in place to protect coral reefs, but “what we don’t have is funding of basic reef processes such as this one, which significantly can affect regional climate in the Great Barrier Reef.”

Research into how ecosystems, such as coral reefs and forests, may be involved in regional climate patterns has been gaining steam over the years. Two Russian scientists have published a number of studies on a controversial theory that forests actually ‘pump’ rain from the coast to continent’s interiors.

If such theories withstand the test of time, and science, they could have widespread implications for the conservation of both forests and coral reefs, adding a new and vital ecosystem-service provided by these two threatened environments: the ‘makers’ and ‘movers’ of precipitation.
