I think the real problem here is the admission that the numbers they use for their analysis and charts are all corrected, not raw data merely averaged and then compared with influences to see where their corrections took them.
No matter what, we know that this is not the same as you writing down what your thermometer says every “
That’s right.
Someone on the blogs studying this analyzed the 0.6 ramp up in temperatures, and backed out the ‘corrections’ and found 0.5 of the 0.6 increase was attributable to the data manipulation/corrections.
So the skeptics are now wondering if there is an underreported UHI (urban heat island) effect in the temperature trends that is over-stating the temp increase.
Consider that the std deviation for any given temperature reading could well be 0.5C. Consider further that temperature can ange by 20C to 30C in a single day.
... and we are talking about a mere 0.6C increase in a supposed global average *over a century*. what are the error bars on that???? This NASA GISS error was a 0.15C one for USA as a whole. This is called ‘small’ but consider that if it was a global temp impact it would be 25% of total global warming for the past century! A 25% reduction would be significant indeed.
There is a lot more room for error in these measurements as well as oppty for data manipulation abuse than the AGW alarmists will let on.
“Somewhere there ought to still be the raw data to be analysed by someone with no ax to grind.”
McIntyre, the climateaudit.org guy who first traced the NASA GISS error, and who uncovered problems in Mann’s ‘hockey stick’ temperature reconstructions, would like the data to do such an analysis. He needs not just raw data, but the data massaging algorithms. Hasnt got them yet. Maybe a FOIA request will get it out of NASA GISS.
I'm not going to hold my breath.
The Hansen's "algoritm" and raw data secrecy combined with this his "full steam ahead" attitude toward drastic global warming action leads me to believe he is hiding something big and just wants to change the world to one that he would like to be.
Why is it that I keep thinking of a muppet skit when I hear the name Hansen?
