Once again using the Moderate Resolution Imaging Spectroradiometer on board their Aqua satellite, NASA have provided this stunning image of the Antarctic Peninsula.
By looking at fossilised pollen found below a hundred feet of dense rock off the coast of Northern Antarctica, researchers have been able to reconstruct a climate record for the southern continent, and determine that the last remnant of Antarctic vegetation existed on the continents northern peninsula some 12 million years ago in a tundra landscape similar to that of northern Canada.
“Lots of people think of the Arctic as just a flat expanse of white. This couldn’t be further from the truth. There are all sorts of cracks (leads) and mountains (ridges), similar to tectonic plates. The ice below is constantly moving via the winds and currents, and those forces acting on each piece of ice makes for a very dramatic seascape”
Scientists believe that the more severe winters suffered by the UK over the past few years are a result of disappearing ice in the Arctic sea. A reduction in sea ice, they explain, could be the reason for the colder winters, which up until recently have been insulating temperature changes in the sea from the atmosphere.
