Islands of Life. A warmer world creates a new iceberg ecology

摘要

Freighter captains avoid them as potential catastrophes; climate scientists see them as a bellwether of global warming. But now marine biologists have a more positive take on the thousands of icebergs that have broken free from Antarctica in recent years. These frigid, starkly beautiful mountains of floating ice turn out to be bubbling hot spots of biological activity. And in theory, at least, they could help counteract the buildup of greenhouse gases that are heating the planet.
