Summary

Story summary

A study in *Nature* estimates global underground carbon storage capacity at 1,460 billion tonnes, far below the 12,000 billion tonnes previously thought.
This capacity may only reduce global warming by 0.7°C, not the previously suggested 5-6°C.
Researchers stress the need for strategic carbon storage and immediate emissions reductions.
The study critiques the unproven scalability of carbon capture technology despite significant investments.
