Preview A unique coral reef in Papua New Guinea shows what the future may hold as oceans acidify.

Watch Wednesday, May 13, 2015 at 9pm on WMHT TV.

A deadly recipe threatens the survival of countless creatures throughout Earth’s oceans. We’ve known for years that oceans absorb about a quarter of the carbon dioxide in our atmosphere. With carbon emissions sharply rising, the silent killer is entering the seas at a staggering rate — raising the oceans’ acidity. As a result, the skeletons and shells of marine creatures that form the foundation of the web of life are dissolving. Follow scientists who are seeking solutions and making breakthrough discoveries, including a unique coral garden in Papua New Guinea that offers a glimpse of what the seas could be like in a half-century. Can experts crack the code of a rapidly changing ocean — before it’s too late?

Phylogenetic trees can tell us where medical problems come from, and how to fight them.
