Climate Change

Warmer temperatures in the North Atlantic over the last several decades have resulted in significantly higher mortality rates of baby harp seals. A new study out of Duke looked at satellite data of ice conditions in the Gulf of St Lawrence, a major breeding region and compared them to yearly reports of dead seal pups that washed up on shore. Lead researcher David Johnston is a scientist at the Duke University Marine Lab:


David Johnston:  These animals have evolved to take advantage of the advan tages of ephemeral surfaces like ice.

A new study out of Duke University finds global warming is forcing tropical birds in Peru to migrate to higher elevations. But it also finds they're migrating at a slower rate than the world is warming.

A new study from Duke University points to tough times ahead for some tree species. Researchers examined data on climate change and the effect rising temperatures are having on tree populations in the eastern U.S. James Clark is a professor of biology and statistics at Duke. He says models that predicted trees would move with the climate were wrong.

A Durham-based environmental group warns utility companies are trying to add nuclear capacity without significantly reducing their use of coal power. A report from NC WARN focuses on what they call the "Southeast Five." That includes both Duke Energy and Progress Energy. Jim Warren is executive director of NC WARN.

  Duke scientists are finding record numbers of humpback whales feeding on krill on the Western Antarctic Peninsula. A new report shows scientists observed more than 300 whales in a bay in May 2009. Scientists say a sheet of ice should have prevented whales from feeding on krill by that time of year. But Duke’s Ari Friedlaender says climate change is shortening the winter season and ice is forming slowly. So the krill are exposed for feeding.

North Carolina has topped many lists in the past few years.  It's one of the fastest growing states and ranks high for its business climate.  But in energy efficiency, NC is wading somewhere in the middle of the pack nationwide.
