Ocean History Lessons: How Corals Can Protect Themselves From Warming

History is a valuable teacher—to natural systems as well as humans, apparently. In a study that could critically shape marine conservation efforts for years to come, scientists have found that sea life can learn from the past just as human beings do. Researchers discovered that corals with heat stress on their health records—meaning periods of [...]

Here’s my longer take in this week’s international editions of the magazine on why the world’s largest protected coral system is [...]

Oceans: From Climate Change to Overfishing, Bad News for the Deep Blue

After all, if we’re supposedly fishing out the seas, why is it easy—and cheap—to get salmon, crab, tuna and any other delicacy you want at the local sushi counter? Why have McDonald’s Filet-o-Fish sandwiches skyrocketed in [...]

Though the sudden bleachings we’re seeing in places like Indonesia immediately have to do with unusually warm water temperatures caused in part by this year’s El Nino, climate [...]
