| Research published this week in the Proceedings of the National Academy of Sciences says that some Arctic ponds are drying up -- despite evidence to suggest that those ponds have been wet for thousands of years. The shallow ponds found in the high Arctic are important ecosystems, freezing solid in the winter but teeming with life during the summertime. Researchers believe the drying of the ponds may be due to global climate change. We'll talk about it. |
