NEW YORK — The warming Arctic has set another record. The average air temperature over Arctic land reached 2.3 degrees Fahrenheit above average for the year ending in September. That's the highest since observations began in 1900.
The new mark was noted in the annual Arctic Report Card, released Tuesday by the National Oceanic and Atmospheric Administration.
''Warming is happening more than twice as fast in the Arctic than anywhere else in the world,'' NOAA chief scientist Rick Spinrad told reporters in San Francisco at a meeting of the American Geophysical Union. "We know this is due to climate change."
Another record emerged for sea ice, which appears when Arctic Ocean water freezes. It was the lowest maximum extent since records began in 1979.
