Remember how all the arctic ice was supposed to be gone this year? Turns out its a sensor problem, and has been for a while... The problem was discovered after they received emails from puzzled readers, asking why obviously sea-ice-covered regions were showing up as ice free open ocean.[^]

I think my favorite part was where they rejected the accurate data gathering techniques because they didn't jibe with what they had gleaned with what has been shown to be faulty methods. I wonder what the odds are of this being covered by any of the networks - even the cable news networks.

LOL! Jeeze, can't you get it right? It isn't global warming, it Climate Change! And by definition, it is our fault and bad. ;P

No, no, that was last week. It is now Planetary Ecosystem Abomination, or PEA for short. You can use it to make PEAsoup.

Dishonest reporting. What a surprise! If you go to the original source, here is what you read:
As some of our readers have already noticed, there was a significant problem with the daily sea ice data images on February 16. The problem arose from a malfunction of the satellite sensor we use for our daily sea ice products. Upon further investigation, we discovered that starting around early January, an error known as sensor drift caused a slowly growing underestimation of Arctic sea ice extent. The underestimation reached approximately 500,000 square kilometers (193,000 square miles) by mid-February. Sensor drift, although infrequent, does occasionally occur and it is one of the things that we account for during quality control measures prior to archiving the data. See below for more details. We have removed the most recent data and are investigating alternative data sources that will provide correct results. It is not clear when we will have data back online, but we are working to resolve the issue as quickly as possible.
http://nsidc.org/arcticseaicenews/[^] So this is a recent and temporary problem and had no bearing on the ice measure during summer.

Is that the dishonest reporting you are talking about?

No, I'm referring to the fact that the Slashdot report makes no reference to the time period affected by the problem and, by discussing it in the context of the summer ice melt, leaves the reader with the impression that the problem could have affected judgments on that issue.

John, do you find anything at all odd about this statement: "a slowly growing underestimation of Arctic sea ice extent. The underestimation reached approximately 500,000 square kilometers (193,000 square miles) by mid-February." In about a month a slowly growing problem created an underestimation of 500,000 square kilometers? In one month? Are they saying that a quickly growing problem would have announced the disappearance of the entire artic ice cap in a month? Their statement by itself, if 100% true, without any help from Slashdot, means their data - all of it - is suspect.

The total sea ice extent is between 11 and 15 million square kilometres. From the article:
Based on comparisons with sea ice extent derived from the NASA Earth Observing System Advanced Microwave Scanning Radiometer (EOS AMSR-E) sensor, this underestimation grew from a negligible amount in early January to about 500,000 square kilometers (193,000 square miles) by mid-February (Figure 2). While dramatic, the underestimated values were not outside of expected variability until Monday, February 16.

From the article:
The daily updates in Arctic Sea Ice News & Analysis rely on rapid acquisition and processing of the SSM/I data. Because the acquisition and processing are done in near-real time, we publish the daily data essentially as is. The data are then archived and later subjected to very strict quality control. We perform quality control measures in coordination with scientists at the NASA Goddard Space Flight Center, which can take up to a year.
So yes, their daily data is suspect.
