Is NASA Too Big for Antarctica?
(thanks to PM for pointing me in this direction)
What is happening about Antarctica, with giant icebergs floating away while the sea-ice cover around the southernmost continent is well above long-term averages?
If you want to understand the situation…do not ask NASA. Because they’ll report everything and its opposite.
- According to “Earth Observatory”, between 1981 and 2007 one can see noticeable warming and cooling trends of up to +/- 0.1C/decade
- In an earlier version, “Earth Observatory” showed a substantially different picture, with warming and cooling trends for 1982-2004 of up to +/- 0.2C/decade. One wonders what were the error bars on this one, and what are the error bars on the recent data.
- “Earth Observatory” “had” to intervene then, in the Wilkins giant iceberg brouhaha
- Then all of a sudden, without any fanfare at all, there comes a March 25, 2008 report from Marco Tedesco at NASA, “uncovered” by Roger Pielke Sr., according to which: (a) “Surface snowmelt in Antarctica in 2008 […] was 40% below the average of the period 1987–2007.” and (b) “the extent of the area subject to melting in 2008 set a new minimum with 297,500 square kilometers, against an average value of approximately 861,812 square kilometers. “
Too bad “Earth Observatory” has not had the time as yet to talk about Mr Tedesco’s work. Here’s some interesting image they may want to consider…
