Diamond Suggests Presence of Water Deep Within Earth

sciencehabit writes "A 40 micrometer crystal trapped inside a diamond unearthed by magma in Brazil could help settle a long-standing debate about the amount of water in Earth's mantle. Spectroscopic analysis reveal that the crystal contains hydrogen-oxygen bonds, which suggests it's composed of at least 1.4% water. The place where the diamond was produced--Earth's lower mantle--may not be typical of the entire lower mantle, but if it is then there could be a lot of water down there. This would be important, as changes in the temperature in the mantle could cause it to expel highly pressurized steam, which could lead to volcanic eruptions."

    It gets worse; the Guardian's comments are full of people sneering about how we are going to destroy this precious natural water resource now we know it's there. Part of me died inside.
