Pick out *one* single picture of an *alleged* weather station, and purport to show data from it corrected and uncorrected. A great little *anecdote*. I’m sure the scientific method could do with much more *anecdotes*, even if they are hoaxes.

Don’t report it directly to GISS for investigation either, just release it directly to the entire world on internet so the skeptics can lap up all the unsubstantiated nuances and spread it around the world via other websites.

However there is one thing that bothers me. What all of my clever scientist/engineering colleagues on this blog apparently neglected to notice is that your clever graphs had displaced y-axis measurements relative to each other.

So in fact, the second graph which *appears* to show unjustified warming in the latter parts of the adjusted segment of the station data, has in fact been obviously corrected so that the *earlier part* has been adjusted downwards. Look at the absolute numbers along the axis, not Anthony’s clever axis shift.

And I bet you guys call yourselves experts in your fields! Ha! How about you correspond directly with GISS on this?

Reply: Yes, the GISS algorithm often cools (adjusts downwards) the past creating an artificially induced warming trend that does not exist in the raw data. At this point more the 70% of the network has been surveyed and once 75% is reached, formal analysis will begin. Did you have a point? ~ charles the moderator, answering for Anthony.

2. The cable, according to the unofficial installation manual can be up to around 500 feet, without effecting the reading, providing there is no leakage due to water, or breaks.

3. One of the main problems with siteing is that the installer has to bury the cable, usually without any cable ditching equipment. This is a time consuming, labor intensive job, which can be wiped out with just one lightning hit near the cable afterwards :o …

The sensor cable could be Direct Burial Rated in which case it is impervious to moisture intrusion; often a gel is used to increase the environmental properties. But if the data cable was Direct Burial Rated it wouldn’t need a garden hose for protection! The shallow burial depth means the cable temperature itself will vary with the day.

It could be the specs allow direct burial, but the homeowner might have decided to use an old hose so if the cable needs to be replaced he wouldn’t have to redig the trench.

Pulling a cable through a partially collapsed rigid conduit is practically impossible from my field experience. A garden hose would be analagous to a completely collapsed conduit rendering pulling a new cable impossible. All cables also have a maximum pull force to protect the cable integrity which is violated in such a pull if the cable ever came through the garden hose….but the owner may have other thoughts.

I have trouble thinking they would thread a cable through 30 feet of garden hose, but a 2 foot weed whacker preventer… I could see that being attractive.

I should be clearer. John Christy’s theory hypothesizes that irrigation, not AGW, is the cause for a “significant rise” in June – November minimum temperatures in the agriculturalized San Joaquin Valley. He completed his study in 2006. If you know of more recent work done to confirm his, perhaps you could post a link. Even so, I don’t know of anyone who is calling this “settled science”.

Christy’s own language in his conclusion is careful:

Conclusions

We have demonstrated a technique to create regionally consistent time series of temperature data based on the assumptions that we are able to identify all significant discontinuities in station records and that the stations are situated in a climatologically homogeneous region. We composited the temperature records of 18 stations in the San Joaquin Valley of central California and 23 stations in the adjacent Sierra Nevada into, respectively, two regional time series for each season. Our analysis of trends begins in 1910 though records are available in earlier years from fewer stations. Our results indicate that the central San Joaquin Valley has experienced a significant rise of minimum temperatures (3°C in JJA and SON), a rise that is not detectable in the adjacent Sierra Nevada. Our working hypothesis is that the rapid valley warming is caused by the massive growth in irrigated agriculture. Such human engineering of the environment has changed a high-albedo desert into a darker, moister, vegetated plain, thus altering the surface energy balance in a way we suggest has created the results found in this study. Additionally, if these results are confirmed, the lack of long-term warming in the generally undeveloped Sierra Nevada (annual mean trend, 1910–2003, −0.02° ± 0.1°C decade–1) coupled with significant, nighttime-only warming in the valley, suggests a regional inconsistency compared with twentieth-century simulations of climate forced by human influences other than land use changes.

The entire study is here, as it appeared in the online Journal of the AMS:

Christy’s hypothesis attributes the warming to the albedo effect caused by changing land used. I’m merely wondering if the same effect is possible here.

John Christy’s research on the irrigation-caused warming of the San Joaquin Valley in California was covered and referred to here several times, although Anthony’s 2007 post had only 3 commenters.

I’m citing the study, too, though I don’t have the time to do additional research on it. The assumption is that desert soils don’t absorb much heat during the day unless they are wet, whereupon they soak up heat like a sponge and relinquish it at night. I’ll try to find out more about the theory.

If this were located here in 2007 it could account for some of the uptrend. Reminiscent of Tucumcari discussion, the quesion of humidity affecting temps. I still wonder if hygrometer readings could be taken concurrent with temps in a running record of both.

That boat is sitting right next to the station and doesn’t look like it gets moved much. On a sunny day it will absorb and store a lot of solar heat, far more than a patch of grass. It will then release it over time in the late afternoon and evenings.

The difference to the surrounding temperature can be quite dramatic especially on calm days.

How is this not criminal fraud? Are there any laws that scientists getting federal money have to abide by? I don’t want to limit free speech and free results in the science community. But this science is so bad, so political, so over the top biased it leaves me speechless. The GISS work has contributed in a significant way to skeptical scientists losing their jobs, etc. Do those who have lost their jobs, denied promotions have any standing to sue? Does RICO apply?

I’d like a lawyer to comment on this type of thing. S. Korea used the legal system during all their DNA fraud cases. I also note, the AGW types seem very eager to use the legal system to achieve their goals.

I think it is dangerous to inject criminal or civil legal issues into science. However, normally universities and science organizations zealously protect their reputation by firing anyone with bad science, or making up degrees on their resumes. I see the peer review process broken and the grey haired guardians of good science sitting on editorial boards, Ph.D. review committees, etc. shockingly AWOL.

…it appears to be a sheilded twisted pair, but they are not even grounding the shield…
Opinions vary but I only drain the shield at one end of the cable run to increase noise immunity and be certain to not induce a ground loop current! Given the garden hose it is likely neither end of the shield is grounded!
