What Florida's mangroves are telling us

December

In today's New York Times:

Much of the Florida shoreline was once too cold for the tropical trees called mangroves, but the plants are now spreading northward at a rapid clip, scientists reported Monday. That finding is the latest indication that global warming, though still in its early stages, is already leading to ecological changes so large they can be seen from space.

Along a 50-mile stretch of the central Florida coast south of St. Augustine, the amount of mangrove forest doubled between 1984 and 2011, the scientists found after analyzing satellite images. They said the hard winter freezes that once kept mangroves in check had essentially disappeared in that region, allowing the plants to displace marsh grasses that are more tolerant of cold weather.
