It's melting...

The BBC have been banging on for a week or so now about how all the ice is melting in the Arctic and how it is all the fault of Global Warming and ultimately us. News reaches me via Bishop Hill that "According to the new RSS MSU satellite data, September 2007 was the 7th coldest month among 81 months since January 2001. It has made it to the 9% of the coolest months of the 21st century so far. Their gadgets measure temperature at latitudes between -70.0 (S) and +82.5 (N) - about 94.5% of the surface if I compute well. In the last month, the global temperature was just 0.12 Celsius degrees above the long-term average which means that it was 0.78 Celsius degrees cooler than the temperature in April 1998 when the anomaly was +0.9 Celsius degrees. The main reason is La Nina that is getting stronger and might continue to do so for a few months."

But I see from NASA that "A new NASA-led study found a 23-percent loss in the extent of the Arctic's thick, year-round sea ice cover during the past two winters. This drastic reduction of perennial winter sea ice is the primary cause of this summer's fastest-ever sea ice retreat on record and subsequent smallest-ever extent of total Arctic coverage. A team led by Son Nghiem of NASA's Jet Propulsion Laboratory, Pasadena, Calif., studied trends in Arctic perennial ice cover by combining data from NASA's Quick Scatterometer (QuikScat) satellite with a computing model based on observations of sea ice drift from the International Arctic Buoy Programme. QuikScat can identify and map different classes of sea ice, including older, thicker perennial ice and younger, thinner seasonal ice. Between winter 2005 and winter 2007, the perennial ice shrunk by an area the size of Texas and California combined. This severe loss continues a trend of rapid decreases in perennial ice extent in this decade. Study results will be published Oct. 4 in the journal Geophysical Research Letters. The scientists observed less perennial ice cover in March 2007 than ever before, with the thick ice confined to the Arctic Ocean north of Canada. Consequently, the Arctic Ocean was dominated by thinner seasonal ice that melts faster. This ice is more easily compressed and responds more quickly to being pushed out of the Arctic by winds. Those thinner seasonal ice conditions facilitated the ice loss, leading to this year's record low amount of total Arctic sea ice."
Oh no the ice is melting and it's all the fault of Man Made Climate Change! Well no, in fact "Nghiem said the rapid decline in winter perennial ice the past two years was caused by unusual winds. "Unusual atmospheric conditions set up wind patterns that compressed the sea ice, loaded it into the Transpolar Drift Stream and then sped its flow out of the Arctic," he said. When that sea ice reached lower latitudes, it rapidly melted in the warmer waters. "The winds causing this trend in ice reduction were set up by an unusual pattern of atmospheric pressure that began at the beginning of this century," Nghiem said."

Go read the rest of the article and wonder if the BBC will cover this news, I think not as it doesn't fit "the narrative".


The BBC also will not report that "The Southern hemisphere was 0.015 Celsius degrees cooler than the long-term average, fifth coldest month since January 2001. Antarctica has cooled down by roughly 1 Fahrenheit degree in the last 50 years." Not true, not listening, ner ner ne ner ner.
