In Bernardo O'Higgins National Park in Magallanes, Chile, a 2-hectare glacial lake has disappeared in what appears to be another case of global warming. The whole body of water simply seemed to evaporate in a span of two months. The discovery was made in late May by park rangers who were shocked to find a huge crater where the lake had been. No, it's not the Silver Surfer's fault. Geologists have concluded, after some deliberation, that melting glacial ice caused the lake's level to swell, putting more pressure on a glacial dam which eventually gave way. It makes us wonder how other bodies of water will fare in these times of warming.
