The Gulf Stream’s Weakening Arm

Again, exceptional infographics tell an important environmental story–it is worth opening if only for the quality of the interactive illustrations:

IT’S ONE OF THE MIGHTIEST RIVERS you will never see, carrying some 30 times more water than all the world’s freshwater rivers combined. In the North Atlantic, one arm of the Gulf Stream breaks toward Iceland, transporting vast amounts of warmth far northward, by one estimate supplying Scandinavia with heat equivalent to 78,000 times its current energy use. Without this current — a heat pump on a planetary scale — scientists believe that great swaths of the world might look quite different. Continue reading

For divers, as well as anyone fascinated by ancient maritime trade routes, this must be the best news in a long while:

Lost World of Shipwrecks Is Found

Archaeologists have found more than 40 vessels in the Black Sea, some more than a millennium old, shedding light on early empires and trade routes. Continue reading
