MUCH MORE CARBON IN EARTH THAN PREVIOUSLY THOUGHT

This article looks at the latest discovery. New research published in Earth and Planetary Science Letters describes how scientists have used the world’s largest array of seismic sensors to map a deep-Earth area of melting carbonate covering 1.8 million square kilometres. Situated under the Western US, 350km beneath Earth’s surface, the discovered melting region challenges accepted understanding of how much carbon Earth contains — much more than previously understood.
