..aren't these the same folks who....


Amateur team finds NASA error similar to one they discovered a year ago.


NASA'S Goddard Institute for Space Studies (GISS) is one of the world's primary sources for climate data. GISS issues regular updates on world temperatures based on their analysis of temperature readings from thousands of monitoring stations over the globe.

GISS’ most recent data release originally reported last October as being extraordinarily warm-- a full 0.78C above normal. This would have made it the warmest October on record; a huge increase over the previous month's data.

Those results set off alarm bells with Steve McIntyre and his gang of Baker Street irregulars at Climateaudit.org. They noted that NASA's data didn't agree at all with the satellite temperature record, which showed October to be very mild, continuing the same trend of slight cooling that has persisted since 1998. So they dug a little deeper.

McIntyre, the same man who found errors last year in GISS's US temperature record, quickly noted that most of the temperature increase was coming from Russia. A chart of world temperatures showed that in October, most of Russia, the largest nation on Earth, was not only registering hot, but literally off the scale. Yet anecdotal reports were suggesting that worldwide, October was actually slightly colder than normal. Could there be another error in GISS's data?

An alert reader on McIntyre's blog revealed that there was a very large problem. Looking at the actual readings from individual stations in Russia showed a curious anomaly. The locations had all been assigned the exact temperatures from a month earlier-- the much warmer month of September. Russia cools very rapidly in the fall months, so recycling the data from the earlier month had led to a massive temperature increase.

A few locations in Ireland were also found to be using September data.

Steve McIntyre informed GISS of the error by email. According to McIntyre, there was no response, but within 'about an hour', GISS pulled down the erroneous data, citing a 'mishap' and pointing the finger of blame upstream to the National Oceanic and Atmospheric Adminstration (NOAA).

NOAA's Deputy Director of Communications, Scott Smullens, tells DailyTech that NOAA is responsible only for temperature readings in the US, not those in other nations.

The error not only affected October data, but due to the complex algorithm GISS uses to convert actual temperature readings into their output results, altered the previously published values for several other months as well. The values for August 2008, for instance, changed by 0.11C and the global anomaly as far back as 2005 increased by a hundredth of a degree.

GISS is run by Dr. James Hansen, a strident global warming advocate who has accused oil companies of 'crimes against humanity'. Hansen recently made headlines when he travelled to London to testify on behalf of a group of environmentalists who had damaged a coal plant in protest against global warming. Hansen also serves as science advisor to Al Gore.

Dr. Hansen could not be reached for comment.

I've read Hansen's evidence and I've read SP4's and is anybody surprised that I believe Hansen?

..because:

(1) none of this is MY evidence and

(2) like most folks who have trouble distinguishing science from religion, you retreat into the falsehoods of folks like your trophy boy Dr. Hansen.

Were Dr. Hansen to do science in any other field, as he does for NASA, he'd be fired. He is a hack. He does rationale-based science, not real hypotheisis-based science. The best part is he has all of you fooled, in the face of glaring failures of his methods. How sad, in the age of information, the average (very average) person still goes with their old biases, instead of informing themselves.

More and more scientists are unwilling to risk their reputations on this hoax and this guy is just one more learned person who is waking up. This is why he will be blacklisted and persecuted. Just watch.

Rapid growth spurt leaves amount of ice at levels seen 29 years ago.


Thanks to a rapid rebound in recent months, global sea ice levels now equal those seen 29 years ago, when the year 1979 also drew to a close.

Ice levels had been tracking lower throughout much of 2008, but rapidly recovered in the last quarter. In fact, the rate of increase from September onward is the fastest rate of change on record, either upwards or downwards.

The data is being reported by the University of Illinois's Arctic Climate Research Center, and is derived from satellite observations of the Northern and Southern hemisphere polar regions.

Each year, millions of square kilometers of sea ice melt and refreeze. However, the mean ice anomaly -- defined as the seasonally-adjusted difference between the current value and the average from 1979-2000, varies much more slowly. That anomaly now stands at just under zero, a value identical to one recorded at the end of 1979, the year satellite record-keeping began.

Sea ice is floating and, unlike the massive ice sheets anchored to bedrock in Greenland and Antarctica, doesn't affect ocean levels. However, due to its transient nature, sea ice responds much faster to changes in temperature or precipitation and is therefore a useful barometer of changing conditions.

Earlier this year, predictions were rife that the North Pole could melt entirely in 2008. Instead, the Arctic ice saw a substantial recovery. Bill Chapman, a researcher with the UIUC's Arctic Center, tells DailyTech this was due in part to colder temperatures in the region. Chapman says wind patterns have also been weaker this year. Strong winds can slow ice formation as well as forcing ice into warmer waters where it will melt.

Why were predictions so wrong? Researchers had expected the newer sea ice, which is thinner, to be less resilient and melt easier. Instead, the thinner ice had less snow cover to insulate it from the bitterly cold air, and therefore grew much faster than expected, according to the National Snow and Ice Data Center.

In May, concerns over disappearing sea ice led the U.S. to officially list the polar bear a threatened species, over objections from experts who claimed the animal's numbers were increasing.
