Doug Ross points out this howler.
The National Snow and Ice Data Center (NSIDC), a global warming alarmist bureau, predicted in May of 2008 that the North Pole would be free of ice last summer.
But it seems they underestimated the extent of Arctic ice by 500,000 km². That's about 190,000 square miles, an area the size of the States of Maine, Vermont, New Hampshire, Massachusetts, Rhode Island, Connecticut, New York, New Jersey, Pennsylvania, Delaware, and Maryland combined — with room left over for West Virginia, South Carolina, and Indiana, to boot.
They weren't using the most accurate methods to measure, but were using older, inaccurate methods because they were in line with their earlier data.
In other words, even though they knew that the methods used to gather their earlier data were inaccurate, they continued to use them for prediction.
