The Arctic ice always recedes in the summer and spreads during the winter. However, last year’s recession was alarming: “By September, the ice cover had declined from its previous low, in 2005, by an area larger than Texas and California combined. The amount of ice in the Arctic has been steadily receding. In 1979 the ice had an area of 2.78 million square miles. Last year, it was only a surprisingly low 1.65 million square miles. It decreased around 44% during the late 19th century. This research has shown that the melt of the Arctic is happening more rapidly than previously though. By using computer models, several scientific organizations place the year of the demise of the northern ice cap to be in 1913 at this point. But no, global warming is a myth, right, now go shovel that rain!
The Effects of Global Warming in the Arctic
The Antarctic is not faring much better. Just recently, ac hunk of Antarctic ice about seven times the size of Manhattan island suddenly collapsed into the ocean. Satellite images show the destruction of a 160 square mile chunk of ice. It was the edge of the Wilkins ice shelf and used to be there for hundreds, maybe up to 1,500 years. This is the result of man-made global warming, said British Antarctic Survey and numerous other global scientific agencies. The rest of the ice shelf, which is about the size of the state of Connecticut, is being held to the mainland by a thin piece of ice and is in severe danger of collapse. Scientists predicted that the Wilkins shelf would collapse in around 15 years from now, so this too is ahead of schedule.
