This morning, another person who also goes by the name of Jim left this comment to a post regarding data on Arctic sea ice extent collected by the National Snow and Ice Data Center:
OK, all this data must be considered faulty because the National Snow and Ice Data Center now admits their sensor has failed and has been delivering faulty data for an extended period of time.
It isn’t just visitor Jim: look here and here and here for the same take, all reading from the same second-hand source, all using failure of a sensor as evidence that the claims of “warmists” are full of crap.
It is true that the National Snow and Ice Data Center has “admitted” one of their sensors has failed. In fact, they don’t just “admit” it; they openly acknowledge its failure. But the rest of what Jim says just isn’t true. The sensor has failed in the past month, but only the past month; data before the very failure of this sensor, using an SSM/I method, matches data from another sensor, the AMSR-E sensor (a sensor using a different method of observation altogether):
The long-term data is reliable; only the data from the past month and only from the DMSP F15 sensor is questionable. Climatologists are accounting for the sensor problem and, because they are employing multiple methods, are not suffering from catastrophic data failure as the people organizing to obfuscate global warming science would like you to believe, and as the uncritical consumers of global warming critique press releases actually, compliantly do believe.
