The oceans are one of our planet's most important carbon sinks, with currently around 39,000 gigatons of carbon dioxide locked away – that's around 50 times more than what's circulating in the atmosphere right now.
of carbon dioxide locked away – that's around 50 times more than what's circulating in the atmosphere right now.However, we can't rely on this carbon capture and storage to solve our climate crisis problem, because we're producing too much excess COWhat's more, a new study suggests that the deep ocean isn't able to hold anywhere near as much carbon as previously thought.
Based on new particle tracking models, it turns out that this process is 'leakier' and retains less carbon long-term than earlier estimates. "In this study, we show that the longevity of carbon storage in the deep ocean may be considerably less than what's generally assumed."Up until now, it was thought that the circulation pathways of the deep ocean would keep every bit of captured carbon that reached a depth of 1,000 meters tucked away from the world for several millennia.
