With this in mind, the researchers estimated that similar rocks across Mars could have trapped the equivalent of up to 36 millibars of atmospheric carbon dioxide.

Especially compelling: the CO2 remains trapped in the rock, taking the place of the oil. Ironically, although carbon dioxide surrounds us, it’s hard to find it in concentrated form.

These openings, thousands of feet underground, can keep carbon dioxide (CO2) trapped underground permanently so we don’t have to allow it into the atmosphere.

This dramatic increase is a result of the re-breathing of exhaled CO2 trapped within the mask. Dr Pirzada explains, "Masks increase the resistance and space volume, leading to a re-breathing of CO2.

Japan’s largest test plant for direct air capture (DAC) technology, which combats global warming by extracting carbon dioxide from the atmosphere, is currently operational at the Osaka Kansai Expo.
