Limited Underground Space Challenges Carbon Storage Goals
A study published in Nature reveals that Earth's capacity to store carbon dioxide in rock formations is much lower than previously thought, estimated at around 1,460 gigatonnes, which could be exhausted by 2200. This limited capacity poses challenges for meeting climate goals, as current and planned CO2 capture efforts are far below the levels needed to significantly reduce global warming, and even full utilization of storage would only modestly reverse temperature rise.
