Seasonal temperatures in the Arctic have reached record highs. The Arctic Ocean is becoming warmer and less salty as sea ice melts, and reindeer herds are in decline as a result of climate change, according to a new report.

“The planet is interconnected, so what happens in the Arctic does matter” to the entire planet, said Jackie Richter-Menge of the Cold Regions Research and Engineering Laboratory

“There continues to be widespread and, in some cases, dramatic evidence of an overall warming of the Arctic system,” the experts said in the third annual Arctic Report Card from the federal National Oceanic and Atmospheric Administration.

The new report, compiled by 46 scientists from 10 countries, focused on specific areas to conclude that the global region is experiencing dramatic and unprecedented seasonal changes: atmosphere, sea ice, Greenland, ocean, biology and land.

Findings from the report include information about Arctic autumn air temperatures, now at a record nine degrees above normal. Reindeer herds, which have been increasing since the 1970s, are now showing signs of stagnation or may be beginning to decline, MSNBC and the Associated Press report.
