Safe, practical underground carbon storage could reduce warming by only 0.7°C – almost 10 times less than previously thought
A new IIASA-led study for the first time maps safe areas that can practically be used for underground carbon storage, and estimates that using them all would only cut warming by 0.7°C. The result is almost ten times lower than previous estimates of around 6°C, which considered the total global potential for geological storage, including in risky zones, where storing carbon could trigger earthquakes and contaminate drinking water supplies. The researchers say the study shows geological storage is a scarce, finite resource and warn countries must use ...
