 Antarctica is cooling/gaining iceThe amount of ice surrounding Antarctica is now at the highest level ever measured for this time of the year, since satellites first began to monitor it almost 30 years ago. All of the IPCC’s models of Antarctica in the twenty-first century forecast a gain in ice, as a warmer surrounding ocean evaporates more water, which subsequently falls in the form of snow when it hits the continent. Other studies, such as Peter Doran’s in Nature in 2003, show actual cooling in recent decades. It’s simply too cold for rain in Antarctica, and it’ll stay that way for a very long time. The bottom line is that there is more ice than ever surrounding Antarctica (source: Patrick Michaels). What the science says...Antarctic cooling is a uniquely regional phenomenon. In fact, the case of Antartica cooling is a great case study on how the media and global warming skeptics seize upon a study and interpret it inappropriately. The original study observed regional cooling in east Antarctica. The hole in the ozone layer above the South Pole causes cooling in the stratosphere. This increased circular winds around the continent preventing warmer air from reaching east Antarctica and the Antarctic plateau. The flip side of this is the Antarctic Peninsula has "experienced some of the fastest warming on Earth, nearly 3°C over the last half-century". While East Antartica is gaining ice due to increased precipitation, Antartica is overall losing ice. This is mostly due to melting in West Antarctica which recently featured the largest melting observed by satellites in the last 30 years. As well as melting, Antartic glaciers are accelerating further adding to sea level rise.
