Ice Increasing at Both PolesSeptember 24th, 2013 at 12:57 pm by Bill Steffen under Bill's Blog, News, Weather
Click on the graphics to enlarge. The Antarctic icecap reached a record greatest extent on Saturday (records since the satellite data began in 1979), reaching 19.51 million square kilometers (12.12 million sq. mi.). Jinlun Zhang, the University of Washington scientist (PIOMAS) who studies Antarctic ice said, “Why would sea ice be increasing…it is a puzzle to scientists.” See the graph on the left, showing that the South Polar icecap is now more than 2 standard deviations above the historic average and the icecap has grown since last year at this time. The 2nd graph shows the steady growth of the Antarctic icecap since the mid 1980s. It’s not “seasonal ice” in Antarctica – you can see the ice has been growing for 25 years (100+ seasons). The 3rd graph shows the dramatic increase in Arctic ice extent in the last year. The area of the icecap is 60% bigger than it was one year ago, the biggest year-to-year increase ever observed in the historic record. While the Arctic icecap remains below average, the icecap is now well within two standard deviations of average. The graphic on the right is ice extent in the western Arctic. The extent is greater than 1981, 1982, 1987, 1993, 1995 and you can see the BIG increase in the last year. Related, 2013 update on polar bears and “global warming” from NPR. It’s debatable whether even a single polar bear has been proven to have perished from “global warming”. However, hundreds of thousands of large animals have been dying from extreme cold and snow: Kashmir sheep/goats, 250,000 alpacas, 70,000 animals in Bolivia, manatees in Florida in 2o10. Also of note, the solar cycle has peaked with a very low number of sunspots (lowest in at least 100 years). This was forecast well by Dr. Leif Svalgaard (note his comment at the first link).
