I would particularly like you to consider the siting of these temperature stations and then observe the temperature graphs associated with the stations.

This site in Marysville, CA has been around for about the same amount of time, but has been encroached upon by growth in a most serious way by micro-site effects.
Let us remind ourselves that it is primarily these stations that NASA GISS, led by James Hansen, is using to justify stultifying our civilisation and from which the predications of doom are being extrapolated.
Here are a couple more stations that are on the GISS network. This first is from Lampasas, Texas, and was drawn to my attention by Climate Skeptic.
Via Anthony Watt is this temperature station in Lampassas, Texas, part of the USHCN and GISS data bases (meaning it is part of the official global warming record).
The temperature instrument is in the white louvred cylinder in the center. This installation is wrong in so many ways: in the middle of a urban heat island, near asphalt, next to a building, near car radiators, near airconditiong unit exhausts. Could we possibly expect this unit to read correctly? Well, here is the temperature plot:
The USHCN data base says that this station moved here in the year 2000. Hmmm, do you think that the temperature spike after 2000 is due to this site, or global warming. By the way, the GISS calls it global warming.
Hmmm. Now, surely these clever scientists have corrected for these problems, right? I mean, they would never use what is quite obviously erroneous data without correcting it, right? Because trillions of dollars rest on the advice that James Hansen and his merry men give. Er...
But James Hansen and others at the GISS defend this station and others to the death. In fact, the GISS extrapolates temperature trends not only for Lampasas but for hundreds of kilometers around this location from this one station. Hansen has opposed Anthony Watt's efforts to do a photo-survey of these stations, saying that his sophisticated statistical models can correct for such station biases without even seeing the station. OK, let's see how the adjust this station. Their adjustment is in red:
According to the GISS, the temperatures since 2000 have been just fine and without any bias that needs correcting. However, they seem to think that the temperature measurement in Lampasas in the 1920's and1930's (when Lampasas was a one horse town with no urbanization) was biased upwards somehow. Why? Well, we don't know, but based on this adjustment, the GISS thinks this site has LESS urbanization today in this picture than in 1900. The GISS adjustments have INCREASED the warming seen at this site. Uh, right.
I think there is some bias that needs correcting, and the place to start may be in the GISS management.
OK, does any one of you think that the adjustments that GISS has made here are right? Do you really think that this station has been utterly unaffected since its positioning here in 2000? Does anyone out there really, truly and honestly think that all of the years before 2000 need to be adjusted downward but that the records after 2000 need no adjustment at all? Oh, and anyone think that I am in the pay of the oil industry for showing you these figures?
Anyone? Bueller? Bueller?
And yet these are the numbers that GISS is using to predict this runaway global warming: no wonder that they are the only agency to maintain that there has been a warming trend over the last ten years. It would be a joke if it wasn't so fucking serious.
I know that there are some people out there who still don't get it, so let's keep on piling on the pain; here is a station in Miami that Climate Skeptic surveyed personally.
For #2, [my son] has posted two USHCN temperature measurement site surveys here and here. The fun part for him is that his survey of the Miami, AZ site has already led to a post in response at Climate Audit. It turns out his survey adds data to an ongoing discussion there about GISS temperature "corrections."
Out-of-the-mouth-of-babes moment: My son says, "gee, dad, doesn't that metal building reflect a lot of heat on the thermometer-thing." You can bet it does. This is so obvious even a 14-year-old can see it, but don't tell the RealClimate folks who continue to argue that they can adjust the data for station quality without ever seeing the station.
Of course, they can: these scientists are fucking geniuses, y'know—they can do anything. Hey! I've got a good game—do you wanna guess what the temperature record is like? Yeah?
Update: Here is the temperature history from this station, which moved from a more remote location away from buildings about 10 years ago. I am sure the recent uptick in temperatures has nothing to do with the nearby building and asphalt/black rock ground cover. It must be global warming.
Once again, I would like to remind you that this station is part of the official GISS temperature measurement record. I want you to bear that in mind as you observe the corrections, as supplied, from GISS data, by Climate Audit (which is, incidntally, written by Steve McIntyre, one of the men who kicked the shit out of the Mann et al. "hockey-stick" graph).
HOMGENIZED GISS DATA OVERLAID ON RAW DATA:
Notice that after the GISS homogeneity adjustment, the past temperatures go down, with the present acting as a hinge point, thus making the slope of the temperature trend rise. The new slope is purely artificial, and appears to be an artifact of data adjustment by NASA GISS on this rural station. This is the second instance of this happening, the first being seen in the GISS Lamapasas, TX data adjustment for homogeneity.
In both cases, the abnormal spike coinciding with a station move near the present time remains in the record, and that is what the homogeneity adjustment is supposed to catch and remove as I understand it.
Now, there is, apparently, an explanation for this. And you're going to love it...
In a comment on the subject, Steve Mosher offers an explanation:In Hansen 2001 Hansen says he uses nightlights to determine if a station is Rural in the US and population everywhere else. Miles city population is less than 10K which makes it rural, BUT, nightlights ( satellite imagery taken in 1995) indicates a brightness factor for Miles of 26! effectively making it urban.
I concur, there appears to be a flaw in the GISS nightlight methodology and adjustment algorithm. I look forward to seeing GISS investigate, and if this problem is indeed verified, a dataset correction.
Yeah, right. Anyone seen those corrections yet?
So, now that everyone's had a look at the pretty pictures, here are a few points to consider: the first is that the "scientists" at GISS are either utterly incompetent or they are lying. In either case, they are not people that we should be taking seriously in any way whatsoever. And yet James Hansen is listened to very seriously—and not just by that great, big charlatan, Al Gore.
The second point to consider—and it's a pretty fucking major one—is that the climate is a complicated—no, very complicated—system and we barely understand all of the interactions as it is; this fact on its own makes all of these climate models pretty suspect.
If you feed false data into those models—and we can see that GISS, at the very least, have been doing so—then those models are absolutely worthless.
And let us further remind ourselves that it is on the outcomes... no, that's too precise, for even the IPCC only calls them "projections"... it is on the projections of these models that we are all getting so very worried about catastrophic anthropogenic climate change.
Now, I'm no scientist and nor am I a statistician, but I can see stupidity and duplicity in the examples that I have posted above: these fuckers are lying and they are stupid to think that they can get away with it (although, of course, ten years ago—before the advent of easy publishing on the web—they would have done so. Indeed, they did do so and they are still trying it on).
Now, can we carry on making our lives better, letting the poor get richer and, in this small nation, forming a sensible policy to ensure that the lights don't go out?
