In particular, a few computers at NASA's Goddard Institute seem to be having a disproportionate effect on global warming. Anthony Watt takes a cut at an analysis I have tried myself several times, comparing raw USHCN temperature data to the final adjusted values delivered from that data by the NASA computers. My attempt at this compared the USHCN adjusted to raw for the entire US:
Anthony Watt does this analysis from USHCN raw all the way through to the GISS adjusted number (the USHCN adjusts the number, and then the GISS adds their own adjustments on top of these adjustments). The result: 100%+ of the 20th century global warming signal comes from the adjustments. There is actually a cooling signal in the raw data:
Now, I really, really don't want to be misinterpreted on this, so a few notes are necessary:
1. Many of the adjustments are quite necessary, such as time of observation adjustments, adjustments for changing equipment, and adjustments for changing site locations and/or urbanization. However, all of these adjustments are educated guesses. Some, like the time of observation adjustment, probably are decent guesses. Some, like site location adjustments, are terrible (as demonstrated at surfacestations.org).
The point is that finding a temperature change signal over time with current technologies is a measurement subject to a lot of noise. We are looking for a signal on the order of magnitude of 0.5C where adjustments to individual raw instrument values might be 2-3C. It is a very low signal-noise environment, and one that is inherently subject to biases (researches who expect to find a lot of warming will, not surprisingly, adjust a lot of measurements higher).
2. Warming has occurred in the 20th century. The exact number is unclear, but we have much better data via satellites now that have shown a warming trend since 1979, though that trend is lower than the one that results from surface temperature measurements with all these discretionary adjustments.

Ping me if you find one I've missed.
So I can visit any porn site except that one? Hmmm indeed!
Interesting.
Double fudging - sounds great in a cookie or ice cream, but not in scientific data.
Well of course that’s adult content. It’s not the childish propaganda everybody is used to see.

Is that blood coming out of my ears? I think my head just exploded. (:^o)
It’s not the computer’s fault, it’s the person who wrote the algorithm that was programmed into the computer. So, indeed, “global warming” IS caused by humans.
I have made some adjustments to a number of games in the NFL this year and I have determined that the Cleveland Browns are undefeated. These adjustments take into account a lot of factors too numerous to go into here. Some are necessary and accurate but others are just for the hell of it.
ALL of these adjustments have been certified by GISS.
Rise of the Machines. We are terminated. (gulp—NOT!)
Preposterous!
Good, I was thinking I’d need a few computers.
A Mac for music stuff, beat up computer off the ‘Net just to store stuff, and an XP laptop for everyday stuff.
I've posted on and off for a few years the true cause for global warming.
Technology involves transfers of energy, but transfers aren't perfect, they give off heat. We're becoming an over-technified world, so there's an excess of heat. And what is the Number One application of technology?? The Internet!
And ... (follow me here) Who was it that took the initiative in inventing the Internet????
Okay, so now you know who is responsible for global warming!
So Gore “invented” the problem and is now sorry for it ? HEADLINE COMING ;-)
Of course it’s an adult site. It’s the “Johnson” Space Center.
If you factor in all the heat given off by the continuing meltdown of the economy (mostly in the form of methane) you will all see that our goose is cooked. It’s been fun knowing y’all.
P.S. I LIKE Baked Alaska.
