Arctic air temperatures climb to record levels
Fall air temperatures have climbed to record levels in the Arctic due to major losses of sea ice as the region suffers more effects from a warming trend dating back decades, a report released on Thursday showed. The annual report issued by researchers at the U.S. National Oceanic and Atmospheric Administration and other experts is the latest to paint a dire picture of the impact of climate change in the Arctic. It found that fall air temperatures are at a record 9 degrees Fahrenheit (5 degrees C) above normal in the Arctic because of the major loss of sea ice in recent years that allows more solar heating of the ocean. That warming of the air and ocean impacts land and marine life and cuts the amount of winter sea ice that lasts into the following summer, according to the report. In addition, wild reindeer and caribou herds appear to be declining in numbers, according to the report. The report also noted melting of surface ice in Greenland. "Changes in the Arctic show a domino effect from multiple causes more clearly than in other regions," James Overland, an oceanographer at NOAA’s Pacific Marine Environmental Laboratory in Seattle one of the authors of the report, said in a statement. "It’s a sensitive system and often reflects changes in relatively fast and dramatic ways."
