Most Laughable Graph of the Week
From NoTricksZone, where Pierre Gosselin writes, "The above chart, from arctic.atmos.uiuc.edu/cryosphere, shows that the Arctic sea ice was in fact quite stable from 1979 to 2002, trending downward only slightly. Then from 2002 to 2007, a period of only 5 years, the sea ice saw almost all of its melting. Over the past 10 years, however, the Arctic sea ice has been stable, even growing some over the past 6 years."
Reminds me of Skeptical Science's escalator graph.
The original graph.
ReplyDeleteThanks Victor.
ReplyDeleteTamino posted on this subject in October. He used changepoint analysis to statistically identify changes in trend, resulting the the stairstep-like appearance of the linear segments. But, he commented on the degree of uncertainty in the shorter intervals, and how evidence of recovery is totally lacking in the data.
