10 years of human CO2 emissions is roughly equivalent to an asteroid impact

There are 1.85 billion, billion tonnes of carbon on Earth, with more than 99% of it resident beneath our feet. Scientists from the Deep Carbon Observatory (DCO) project have spent 10 years assessing the “reservoirs and fluxes” of the chemical element. In other words, they worked out where carbon is held and in what form, and how it moves through the Earth system.

The findings will help understand the limits of life on our planet and in the forecasting of volcanic eruptions.

“This work really came out of the realisation that much of the carbon that we are concerned about for climate change is only a tiny fraction of our planet’s carbon...
