SUMMARY: In addition to negative consequences caused by overfishing and pollution, coral reefs face another major existential threat: increased acidity from warming oceans. Hari Sreenivasan reports from Florida about the dire outlook for coral reefs, as well as efforts and research to try and save them.
GWEN IFILL (Newshour): Next: the decline of coral reefs and the connections with rising levels of carbon dioxide.
New reports this week show there were nearly 38 billion tons of carbon dioxide emitted around the globe last year. That, among other things, is having a very real effect in places like the Florida Keys.
Hari Sreenivasan traveled there recently and filed this report for our series Coping With Climate Change.
