Recent studies show extreme rises in worldwide sea level and Arctic temperatures. The Proceedings of the National Academy of Sciences recently released the sea level study. It shows sea levels rose faster in the 20th century than in any of the 27 centuries before. The researchers say that from 1900 to 2000, sea levels rose 14 centimeters. Robert Kopp of Rutgers University in New Jersey is the lead author. He called the 20th century sea level rise “extraordinary.” And, Kopp said, “The rise over the last two decades has been even faster.” The study shows that without a warming Earth, sea levels would have dropped by three centimeters and risen by seven. Co-author Stefan Rahmstorf is a professor of ocean physics at the Potsdam Institute for Climate Impact Research in Germany. He says sea levels will continue to go up. How much and how long? The research shows levels could rise more than a meter by the year 2100. Scientists from NASA and the National Oceanic and Atmospheric Administration did the Arctic temperatures study. It found that temperatures at the North Pole hit record highs in January. This news comes after scientists said 2015 was the hottest year ever recorded. Scientists also have noted a huge area of unusually warm water in the northern Pacific Ocean. They say it keeps air temperature about three degrees warmer than usual in that area.
