Many thanks to : “tty” in a comment under the thermometers posting for pointing me to the following graph:
Uppsala Sweden 1722 to 2005
Per tty:
“That is the temperature record for Uppsala, Sweden 1722-2005, one of the longest and best temperature series in the world, courtesy of SMHI, the Swedish Weather Service (which is rather pro AGW). ”
So what do we see when we look at this graph? A really big dip with the bottom at right about 1880. I think we now know why GIStemp picked 1880 as the date for cutoff for old records. There is also a nice little local droop over the 1950 to 1980 “baseline” visible in the graph.
We wouldn’t want that very warm 1720-30 period or even those average late 1700’s messing up our nice little trend out of the dead bottom of the last minima of the Little Ice Age…

Thanks for posting this. This graph should get world-wide exposure. I will definitely use this data in my presentations click
Btw, does anyone know if other long-term temperature data-sets exist?
Hi EM,
Your ‘there is no shortage of energy’ blew me away, thank you. Having followed the AGW argument for years I came across the Armagh series a few years back, saved the PDF but can’t trace the link, short title search below will get you there.
AIR TEMPERATURES AT ARMAGH OBSERVATORY, NORTHERN IRELAND,
FROM 1796 TO 2002
There is also a ‘Central England Series’ that covers a similar period. I will be a regular viewer from now on, and will refer folks who mention ‘Peak Oil’ here!
Peak Oil: Peek and ye shall find.
there is a sign wave there, wish i could amplify it!
is it an amo? nao? effect?
It’s not clear where the “waves” come from (at least, not to me, yet). They seem to correlate with planetary influences on solar angular momentum, but that could be a statistical artifact or it could be a mutual correlation with some other causality.
That is looked at here:
That it’s not people doing it is fairly clear…
i m interested in plucking cherries in sweden if you do have some information kindly send me through my mail address. as i m student and just free during this summer season so i want to do some work. kindly help me in this case.
