Concern over Greenland


The latest satellite images of Greenland are clear and very worrying. Son Nghiem from NASA not even believe what he saw in his first review, doubted whether there was any error in the data, so test a campaign promoted by the world and corroborated: the pictures were true to life, Greenland had lost 97% of ice 2 to 3 km thick in a few days. Since the mid-nineteenth century is becoming a thickness monitor this mysterious island of geological origin, since access to the rocks to check its origin is difficult, but now we have at hand. They had never reached these summer melt rates and less at that speed, on July 8 to 40% affected, day 12 to 97%. After shedding a few days ago of an iceberg the size of Manhattan Petermann Glacier is the third strange thing happens to the island. The other is the discovery of the oldest crater on Earth about 100 km in diameter and about 3,000 million years. Such visibility must be seized. Speculation about climate change have regrown, if yes, otherwise, if data is missing ... The fact is that so much fresh water (four times Spain by 2 km thick) poured into the ocean a few days, will bring consequences in the medium and long term. In a few days, has been spilled into the ocean so much fresh water is equivalent to ten times all the Earth's freshwater lakes, rivers, springs ... According to recent research from the University of Potsdam, if global temperature would increase by about 2 ° and we think this way, would melt all the ice that remains in the Arctic. The sea level rise would be about 7 m and almost all the coastal cities of the world should be abandoned. It looks like a scary movie, but the announcement comes from far away. But if you look at the short term, ie for the coming months, do not talk about trifles. Perhaps the jellyfish, which are indicative exceptional as fires, while effects of the matter, and advising us came from the north and south, but the consequences for our near future are at least disturbing, see : First such change amounts of fresh water mixes with salt water, the great ocean currents, so it trastocará a little weather, fires, floods and droughts in unusual places are already circling. Also the wind, its direction and its intensity will be affected, we do not know when or where but the hurricane season will be exceptional. If you also concentrate much weight has gone from a particular area of ​​the Earth, it tends to rebalance, as the globe we inhabit is more like a custard than a soccer ball, resulting in a cortical tension adjustment, an effect domino can hit in the form of earthquake anywhere. Let us hope that all these issues of climate change and geometric our home-planet are fantasies and "sacaperras" agencies such as NASA and the University of Potsdam, and that politician's cousin is the really consistent.
