Shocker: Healthy coral reefs produce clouds and rain

10

Dr. Graham Jones has been researching coral reefs and coastal precipitation for over 20 years. And all that research has paid off with the discovery that “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,” said Mr Jones. Interestingly, Jones said that “water vapor cannot form clouds without these tiny aerosol particles being present.” The DMS is produced by the algae living in coral tissues, causing the corals to produce the cloud-seeding substance, DMS, on a daily basis. If coral reefs do make more clouds that deliver rain, how long before we start to harvest DMS for cloud seeding? And you might want to get an umbrella for those of you who have larger reef tanks in your house. You know, in case it starts raining.

    Unfortunately Graham Jones and his team have now discovered that a rise in ocean temperature of only 2 °C causes some algae to stop producing DMS. This means fewer clouds are formed, heating the water even more. :(

    Wow, that one just strikes me out of left field, corals help produce rain clouds?

    Kind of ironic is the greenhouse gasses might be responsible for the rise in temperature of the oceans but the corals themselves help create water vapor (clouds) in the air of which water vapor is a pretty vicious greenhouse gas

    Mike,
    I don’t really understand your point, clouds play vital part in regulating Earth’s climate, cooling down the local climate and causing rain.
    It’s true that clouds are green house gasses, but According to NASA, “The overall effect of all clouds together is that the Earth’s surface is cooler than it would be if the atmosphere had no clouds.”

    That should explain why it still rains in Bohol , Philippines while the fields of Northern Luzon and Mindanao islands in the Philippines are cracking dry. Most Boholanos are taking care of the corals in their sea beds.
