Arctic ice melts to record low: US researchers – Yahoo! News.

The sea ice in the Arctic Ocean has melted to its smallest ever level in the latest dramatic sign of the long-term impact of global warming, US researchers said Monday.

Scientists at the University of Colorado at Boulder said that data recorded Sunday broke the 2007 record for the lowest extent of sea ice and that the melt could become even more significant with several weeks of summer left to go.

The National Snow and Ice Data Center at the university said in a statement that the decline in summer Arctic sea ice “is considered a strong signal of long-term climate warming.”

The sea ice fell to 4.10 million square kilometers (1.58 million square miles), some 70,000 square kilometers (27,000 square miles) less than the earlier record charted on September 18, 2007, the center said. Click above link to read more.
