Over on WUWT, there was a comment:
by Harold Pierce Jr that pointed to a rather fun little site:
For quick and easy access for weather data from anywhere go to:
On the hompage, enter info request in the input box . For example, “weather alice springs”. Click on red box with equal sign. The computer them retrieves and displays weather data for the present date from about 1940 if it can find it.
In the section “Weather History” click on drop down menu for addditional selections for display of weather info. Plots of various weather metrics are displayed and other info such as record highs and lows. There is also a short term weather forecast available.
If you select “All”, a plot of the annual mean temperature is diplayed with the OLS trend. For Alice Springs this is really low like almost zero. Note data is from airport.
If no info can be found, a definition about weather and climate is displayed.
Thinking this might be a bit of fun, I put in “Darwin Temperature”. They proceeded to figure out I likely did not mean the other Darwins… “Assuming Darwin (Australia) | Use Darwin (Minnesota, USA) or Darwin (California, USA) instead” …
and made a nice little graph. Unexpectedly, even I was surprised at how flat it was. I’ve grown so used to the GISS graphs being all out of whack, I guess the idea that an online source would be correct kind of surprised me:
I’m resisting the temptation to start typing in all sorts of cities world wide to see what it shows… and comparing them to my copy of GHCN…
Though not very successfully… Here’s the graph for Sacramento, California:
I can tell this is going to be an issue for me for a few days…. Here’s an interesting comparison of some Arizona sites. First up is Phoenix that has grown like a weed, then Tucson that’s grown, but not nearly so much, and where the airport has not got quite so many acres of asphalt / tarmac in all directions…
You can drive from Phoenix to Tucson in a very few hours ( I have, recently) and the terrain does not change much (at all?). These two ought to be nearly a ‘matched set’, especially on things like distance to ocean and influence of Canadian Air… Yet what we see is clear evidence that Phoenix has a very bad Heat Island.
Moving “up slope” from Phoenix on a one day drive, you can rise through Prescott to the mountain tops at Flagstaff:
While these time periods are too short to cover the known weather cycle period lengths, they clearly show that the trend is not at all like Phoenix. There is a bump up during the warm phase of the PDO, then a drop back down during the cold phase. There are some differences at the end of the cycle in timing that are interesting (that could be equipment changes? Or just differences with altitude? Or clouds or??? )
“Global Warming” comes from the selection of places like Phoenix Sky Harbor Airport as the thermometer to use to represent this region, then averaging and blending it into all the surrounding areas. There is no general warming away from the major urban centers and airports. It is the “homogenizing” and “averaging” process that leads to a splice of sites like these that hides these variations and the story they have to tell which is, IMHO, the basic core fault in “Global Warming science” as practiced today.
UPDATE 2 – Adding graphs that some folks have talked about in comments
Two From Idaho:
One from Benson Air Field near Oxford England:
Some Islands In The Sun:
Bikini Atol actually comes up as Kawajalein (Buchholz AAB, 254 miles SE of Bikini, but it probably doesn’t matter all that much, other than that it is another airport). You need to keep an eye on what it interprets a place to be sometimes:
One I rather like (as I think it shows the PDO state switch both ways):
For comparison to Midway, here is the International Airport at Lihui Kauai. I think you can see the fairly clear “step function” as the Jet Age began and it turned from a 1940’s grass field and 1960s “Puff The Magic Dragon” sleepy getaway into a major tourist destination, then stabilized after that massive airport growth into the 1980s. It would be interesting to know what was done at Midway in the 1990s.
