[QUOTE="Old Man Jingles, post: 4362451, member: 18222"] [B][URL='https://www.nasa.gov/topics/earth/features/warmingpoles.html']What's causing the poles to warm faster than the rest of Earth?[/URL][/B] Luckily, scientists continue to investigate why Global Warming is occurring. Research aimed at answering that question has been done before, but a recent study by Patrick Taylor, a scientist at NASA's Langley Research Center in Hampton, Va., suggests a new reason. Taylor's research shows that the seasonality of the polar warming is largely a result of energy in the atmosphere that is being transported to the poles through large weather systems. Temperate Zones are not affected as much as the Polar Zones. This is a pattern that has also been documented from drilled ice samples and drilled earth samples. As well, decades of NASA scientific research show the Earth is warming. According to NASA's Goddard Institute for Space Studies in Manhattan, the Earth has warmed about [B]1.44 degrees Fahrenheit during the last 40 years[/B]. But the poles are warming even faster; the Arctic has warmed by more than [B]3.5 degrees Fahrenheit during the same time period[/B]. "It was previously thought that amplified polar warming was caused by melting ice, lowering surface albedo," Taylor said. Albedo is the amount of sun’s energy that is reflected off the Earth’s surface and back into space, rather than absorbed. The more reflective the surface – such as ice – the more energy is reflected and the cooler the temperature. When ice melts, less energy is reflected and temperature increases. "Surface albedo at the poles, however, is lowest in the summer, which is when we see the weakest temperature response. More recent research suggests that other atmospheric processes are at work," Taylor said. [/QUOTE]
