Unprocessed-Climate-Variation-In-North-Atlantic-Connected-To-Greenland-Ice-Sheet-Melt

Scientists have been familiar of the warming global climate phenomena is melting Greenland Ice Sheet. A contemporary study from the Woods Hole Oceanographic Institution (WHOI) however represents the rate of melting might be momentarily escalated or dwindled by two prevalent climate sequences, the North Atlantic Oscillation (NAO), and the Atlantic Multidecadal Oscillation (AMO).

Bot sequences can render a prominent impact on regional climate.  The NAO which is calculated as the atmospheric pressure contrast between the Azores and Iceland can impact the stance and the robustness of the westerly storm track. The study showcased that when the NAO exists in its negative space it can propel paramount ice melt in Greenland during summer season.

Similarly the AMO which amends sea surface temperatures in the North Atlantic can pose prominent melting events when it is in its sultry phase elevating the temperature of the area entirely. If global climate change persists at its present rate the Greenland ice sheet may finally melt totally but whether it encounters this fate sooner than later could be bent on by these two  oscillations, says Caroline Ummenhofer, a climate scientist at WHOI and co-author on the study.

Based on how the AMO and NAO intercommunicate surplus melting could occur two decades before anticipated. Ummenhofer said that it is known that Greenland ice sheet is melting partly because of warming climate but it’s not a definite procedure. There will be phases when it expedites and phases where it won’t.
