Scientists have just discovered a 1.8 million square kilometre lake semi-molten carbonate (CO2) compounds under our feet – but still think the contribution of volcanoes to the annual CO2 emission budget is insignificant compared to human emissions.
Scientists uncover huge reservoir of melting carbon under Western United States
February 13, 2017
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 carbon covering 1.8 million square kilometres. Situated under the Western US, 350km beneath the Earth’s surface, the discovered melting region challenges accepted understanding of how much carbon the Earth contains – much more than previously understood.
“It would be impossible for us to drill far enough down to physically ‘see’ the Earth’s mantle, so using this massive group of sensors we have to paint a…
