How Climate Change Could Threaten The Food Supply

Climate change often sparks concerns over rising sea levels and melting ice caps. But its impact on agriculture could be just as devastating. A new report from the US Department of Agriculture highlights the potential problems and how farmers will have to adapt.

shrinking polar ice caps, rising temperatures, vanishing forests, acidic oceans and superstorms. Welcome to the new planet earth. A renowned environmental writer came up with this new spelling of Earth - Eaarth - because the planet we live on no longer resembles the planet we used to live on. The new planet has a new name.

UNC Working to Save Native Species in Galapagos

Native species on the Galapagos Islands like sea lions and "Darwin's finches" are under threat from tourism and climate change. UNC researchers are working to find ways to save these species. The UNC Center for Galapagos Studies

The Galapagos is a chain of 13 large islands about six hundred miles from the coast of Ecuador. It was there, in 1835, that the British scientist Charles Darwin began thinking about how animals change over time. Since then, scientists have called the Galapagos a living laboratory,  a place to study evolution and natural selection. Now, with 180,000 tourists visiting each year, experts say the living lab is in danger, and University of North Carolina-Chapel Hill scientists are stepping up to help.

NC Wraps Up One of its Warmest Winters

It's the first day of Spring but it may feel like winter never really settled in. State Climatologist Ryan Boyles says it was the 8th-warmest winter on record in North Carolina and the 6th-driest. He says that's had some up-sides.

Ryan Boyles: Recreation has been much higher this year; people have been able to really get out and enjoy the outdoors this past winter because we've had such mild temperatures. Snow removal costs have been very small this past winter, especially compared to the previous two winters. But there are some negative impacts as well.

Study: Climate Change Altering Bird Migration

There's more evidence that climate change is altering bird migration patterns. A new study from UNC-Chapel Hill finds some species along the east coast are migrating three-to-six days earlier than they were just ten years ago. Allen Hurlbert is an assistant professor of biology at UNC. He says birds face problems if they get the timing wrong.

New Planting Map Shows Warmer Winters

The US Department of Agriculture says winters aren't as cold as they used to be in North Carolina. It has released its first new map of planting zones in more than 20 years. Tony Avent is the owner of Plant Delights Nursery in Raleigh. He was a technical advisor on the map. He says its detailed, interactive features surpass anything previously available.

Harp Seals Dying as Ice Shrinks

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.

Climate Change Forcing Tropical Bird Migration

Deep-blue Flowerpiercer

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.

Rising Temps Tough on Some Trees

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.
