. Down south, the Antarctic gained the most sea ice seen in that same period. Not surprisingly, some climate skeptics jumped on this observation as seeming evidence that polar changes somehow even each other out. Nothing could be further from the truth. There are good reasons why sea ice differs between the poles, cheap jordans for sale , and growth in the south doesn’t counterbalance loss in the north. For starters, cheap jordan shoes , look at the magnitude of the changes. Antarctica’s winter sea ice maximum is growing, but slowly: Between 1979 and 2012, cheap real jordans , its average September extent grew by just under 1 percent per decade. Up north, over the same time period, cheap jordans online , the area covered by sea ice in September has been dropping by 13 percent per decade. Around Antarctica, cheap wholesale jordans , the sea ice fringe this year was about 1 million square kilometers above the 1979–2000 average (a time period often chosen to represent the “old normal” of sea ice conditions). In a different but telling measure in the Arctic, this year’s loss between the winter freeze and the summer melt is 11.83 million square kilometers, cheap jordans , the largest seasonal loss by far in the satellite record. Put yet another way, http://cheapjordansstock.com , Antarctica is gaining a Connecticut’s worth of ice each year, while the Arctic is losing an Indiana. Why the difference? Because while Arctic changes are dominated by air and ocean temperatures, cheap retro jordans , Antarctic changes are all about winds and ocean currents. As Arctic sea ice melts, it exposes the darker water beneath. This open expanse absorbs more of the sun’s incoming energy and sets up a feedback loop that melts more http://www.sucre-info.com/./index.php http://www.everyq.com/...-Cheap-Jordans-Stock-Sale http://bjaeldemosegaar...hread.php?thread_id=21839 |
