This Scientist Aims High To Save The World's Coral Reefs
Caldeira works for the Carnegie Institution for Science, and he's based on the Stanford University campus. But throughout February, his base of operations was One Tree Island, Australia.
He spent many a day out on the reef, wearing a floppy sun hat, tattered shorts and a head-to-toe "rash guard" to block the intense sunlight. He and his team were pumping antacid onto a stretch of the reef to see if neutralizing some of the increased acidity would help the coral grow faster..."
...Decades ago, everybody was smoking cigarettes — and it was acceptable to smoke cigarettes indoors," he says. "And there was a phase change in social acceptability, where it is no longer acceptable to dump your cigarette smoke in air that somebody else is going to breathe. And I think we can achieve the same thing with carbon dioxide emissions, where it just becomes socially unacceptable to dump your industrial waste into the atmosphere."...NPR sent science correspondent Richard Harris to Australia's Great Barrier Reef to spend some time with Caldeira, a scientist who thinks big.
