Randy Atkins: Our carbon dioxide emissions are huge.  But David Goldberg, a Columbia University scientist, has mapped 25-thousand square miles of honeycombed volcanic rock formations on the Pacific Ocean floor and…

David Goldberg: If you calculate our current emission rate of the entire U.S., you’ve got 100-plus years of emission that we would potentially be able to store there.

Randy Atkins: Goldberg says we need to engineer economical ways to capture carbon dioxide, turn it into liquid, and pump it into the spaces within those rocks.  He says it can be securely stored there and, through the years, a chemical reaction would turn it into a safe chalk-like substance that hardens permanently.

David Goldberg: The CO2 is in place and will stay there without risk of returning to the ocean or, ultimately, to the atmosphere.
