Safe Underground Carbon Storage Would only Reduce Warming by 0.7°C, Analysis Finds
The study reveals safe underground carbon storage can only store 1,460 billion tons of CO2, limiting global warming reduction to 0.7C, far less than prior estimates.

How much carbon can we safely store underground? Much less than previously thought.
Drawing down carbon from the air and stashing it in underground rock formations has been framed as an essential way to slow and reverse global warming. But new research published Wednesday in the journal Nature finds there are far fewer suitable places to do this than previously thought. After screening out “risky” areas, like those that are vulnerable to earthquakes, a team of researchers from Europe and the U.S. found that the Earth can only s…
Safe underground carbon storage would only reduce warming by 0.7°C, analysis finds
For the first time, a study 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…

Experts from Austria have investigated the potential of the technology, which is often praised as a miracle weapon against climate change, for the storage of climate-damaging carbon dioxide.
For the first time, a Cartose study of safe areas that can be practically used for underground carbon storage, and estimates that using them would only warm up by 0.7°C. The result is almost ten times lower than the previous estimates of about 6°C, which considered the overall potential [...]
