Long Term Temperature Trends In Warsaw

There are very few complete temperature records that date back to the 18thC, and one of these is in Warsaw. Reader Sleepalot sent me the CRUTEM data for Warsaw, that began in 1779, and runs through to 2010.
Figure 1 plots the annual data, along with a 30-Year running average.

Temperatures have certainly increased since 1779, and the 30-Year trend shows a small uptick in the last decade or so, as we might have expected. But the interesting thing is that the really significant increase occurred in the late 19thC and early 20thC.
I wonder how many SUV’s there were in 19thC Warsaw?

NOT A LOT OF PEOPLE KNOW THAT 
“I wonder how many SUV’s there were in 19thC Warsaw?”
Or, Climate Researchers, seeking grants to scaremonger.
How many witches did they burn ? 😉
Just image if climate science had existed in the late 19th century.
All of the major inventions that shape modern life would have been banned before they were intoduced – no cars, no lorry’s, no planes, no power plants, few advancments in agriculture, no electricity for the people which means that other discoveries from the last century like computers, TV/media, vaccines and cancer cures would not have been discovered either. We’d have been told to stop polluting immediatly as the world will end from heat/floods/tornado’s before 1930 if we don’t.
Strangely though, we continued polluting, even increasing it dramatically and yet we are still here and doing well……….
Hi Paul, where can I find the Warsaw data? do you have a link? thanks.
You can download them here (the July 2011 file).
Warsaw station code is 123750.

Got it, thanks for the station code that was helpful.
Interesting to see they removed the X10 from temperatures. That was a little “fuck you” from Phil Jones to anyone wanting to review his work.
Also, “A value of -99 indicates missing data.” is not true: it indicates missing or removed data. Sheffield shows that the MO has a complete dataset (from about 1924), and the CRU wiped out over 30 years of it (1978 onwards).
Investigating annual T°C at a latitude of Warsaw may be not necessarily too helpful to recognise the important factors of a climatic shift, as it difficult to separate the influence of the sun. For example: Fig. 1 shows that since the end of the Little Ice Age around 1850/60 the lowest temperatures occurred immediately after 1939, respectively only few months after WWII started on 1st Sept. 1939. If one concentrates on the winter temperature (D/J/F) the finding is amazing. As I have no such access to those of Warsaw, here are those from:

A look at the three initial three war winter compared to the previous three winter in a global context, shown here: http://climate-ocean.com/book%202012/a/a3/mid/big/A3b-3_TM2.png
indicates that before 1939 the winters were very mild worldwide, which continued generally, but without Europe, which experienced in some parts the coldest winters since 1820.
After minimising the effect of the sun /(due to a look at the winter season) it might be easier to identify the reason for these extreme winters.
