Two significant climate stories suggest that global warming is ocurring at a faster pace than the conservative estimates established by some climate models.
Glaciers in Argentina and Antarctica are showing significant melt during the winter, a time when melting generally stops and additional snow pack is added to these monstrous lakes of ice.
Reuters reported that a large section of the glacier known as the "White Giant," a popular tourist attraction in the Patagonia region of Argentina, collapsed last week.
It’s the first time the glacier has broken during the winter, since the park began keeping records, according to one park warden.
An MSNBC report today said that satellite images reveal that a 6,000-square-mile section of Antarctica, called the Wilkins Ice Shelf, is continuing to melt through the winter, due to warm ocean water.
David Vaughan of the British Antarctic Survey said, "Current events are showing that we were being too conservative, when we made the prediction in the early 1990s that Wilkins Ice Shelf would be lost within 30 years."
