Polar meltdown? NOT!April 22nd, 2009 at 12:39 pm by Bill Steffen under Bill's Blog, Weather
According to the University of Illinois (and my wife has a B.S. and M.S. from the Univ. of Illinois at Champaign and she’s pretty smart, so I’d believe them) Antarctic sea ice is nearly 1,000,000 square kilometers above the 1979-2000 normal. That means that the excess sea ice would cover an area about the size of Michigan and California combined! According to the National Snow and Ice Data Center in Boulder, CO – Antarctic sea ice has grown at the rate of over 4% per decade over the past 30 years and reached an all-time maximum in 2008. You haven’t heard this reported in the mainstream press. What they have reported is the ice breaking off the Wikins ice shelf - which would represent about one pixel on the map here. Calving of ice off the shelf is a common and natural occurrence. Meanwhile in the Arctic – the icecap has grown more in the past 16 months than in any 16-month period on record. See this graph which shows the Arctic icecap decreasing steadily from 1979 to Sept. 2007, and then increasing at a relatively rapid rate since Sept. 2007. This is the similar graph of Antarctic ice, which has been increasing slowly since about 1986. Barrow, Alaska has averaged -5.6 deg. for April and this will be their 3rd consecutive month with temperatures below average. Anchorage, Alaska has had below average temperatures for each of the last 12 months. Nome, Alaska is 8 deg. colder than average for April and they still have 52″ of snow on the ground! Whittier, Alaska still has 81″ of snow on the ground. Note the ice in the Bering Sea. At the town of Alert in northern Canada, the average temp. this month has been -19.5F. Alert made it to +6 on Tuesday. That was the warmest temperature since last Oct. 10. The last time the temperature was above freezing in Alert was last Sept. 3. On the other side of the North Pole, Oymyakon in Siberia hasn’t been above 40F since last September and Verkoyansk finally made it to 40F on Sunday for the first time since Oct. 3. Here’s recent ice trends in the Chukchi Sea. The Arctic icecap is still about 500,000 km. below the 1979-2000 average, but that number has been shrinking in the last 16 months – certainly not a long enough time to establish a trend, but this should be taken as good news from all sides of the climate issue. If you take the 1,000,000 km. of excess ice at the South Pole and subtract the 500,000 km. of excess open water (below average ice) at the North Pole – you get 500,000 km. ABOVE the historical average! You could fit both Michigan and Al Gore’s home state of Tennessee into that area of excess surface ice! Please take a moment and read more HERE.
