Global warming?

Photo shows the Mertz Glacier, a 160-kilometer spit of floating ice protruding into the Southern Ocean from East Antarctica. Researchers have said that the iceberg the size of Luxembourg - or some 2550 square kilometres (985 square miles) in size - knocked loose from the Antarctic continent earlier this month and could disrupt the ocean currents driving weather patterns around the globe. While the impact would not be felt for decades or longer, a slowdown in the production of colder, dense water could result in less temperate winters in the north Atlantic.
