GISS's October Data. The large reddish-brown area in Russia is actually September readings.
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.

That's a little disingenuous. The Earth is cooler than it was in 1998. But that doesn't mean the Earth has been getting cooler for the past 10 years. Temperatures cooled between 1998 and 2002. They plateaued in '02, and have been pretty much constant since then. What is more, some models predict that temperatures will stay cooler for the next decade or so due to natural cooling phenomena, and then bounce back up due to the combined effects of natural warming and human activities.

Still, I don't know what all the fuss is about. Global warming or no global warming, I think we should be taking the same steps to reduce our impact on the environment. To reasonable levels - I'm not suggesting we all run into the woods and wear ferns.

It's funny. I actually do have a windmill and a 65W solar panel, plus I eat bugs (lobster - they count right?). But none of it is to reduce my 'carbon footprint.' I live on a boat at anchor. It would cost too much to live at a dock where I could be hooked up to the grid, so I make do with alternative energy sources. But these are just my lifestyle choices, for my reasons. That doesn't necessarily invalidate your basic point.

But what about this argument: it's called democracy.

We put things to a vote, and the majority gets to set the agenda, as long as it doesn't infringe on the rights of the minority opinion. And the last time I checked, there wasn't anything in the Constitution about the basic human right of cheap electricity. Not even in the penumbras and emanations. So you may not have a choice but to spend more money to maintain the same carbon footprint you have.

Give this man a 6 for taking a reasonable standpoint -- rather than working toward the extreme of his preference.

just a small point - the origin of the predicted global heat-up in many models is the in-build assumption that hte earth will heat up.
Just like in this article, where errors in the october 2008 data has an effect back to 2005. global climate models are very much like the stock market. Based on assumptions that can't be proven, fed with data manipulated to fit the assumptions and financed by poeple with a vested interest in the outcome.

I do not say they are wrong - but their validity is very hard, if not impossible do verify.
Also, there is nothing wrong with taking resposibility for your impact on anything. There is something wrong with trying to force or fake others to your way of thinking.

I don't need to fake anybody into my way of thinking. I don't need to force them into my way of thinking. Eventually, the government will probably force them into certain actions. Actions with both environmental and economic impacts. Actions that I freely admit I don't currently practice.

As for the models, yes, there are lots of models out there that predict lots of different outcomes predicated on the same data but lots of different assumptions about the effects of different climatological phenomena. Which points out that there is no consensus among climatologists about the exact extent of global warming. The exact forcing that CO2 exerts isn't clear, even.

If by "reducing your environmental impact" you mean driving a hybrid, not eating meat, switching to 100% solar and wind, buy carbon offset, etc. then no.

If you mean try to recycle, use more energy efficient appliances, try to carpool, buy a sedan instead of a Suburban, etc. then ok. But I should have the choice. And I shouldn't be punished for choosing the choice you don't agree with.

The problem is that the false god of Global Warming distracts us from what's really important: reducing pollution. Now there are a lot of people driving diesels which a) reduce CO2, but b) increase particulate pollution. They've been told they're "saving the planet" but really they're just making it dirtier.
