No Trend In French Summer Temperatures

The average afternoon summer temperature in France is about the same as 100 years ago, as is the frequency of hot days. This summer has been unusual not because of the number of hot days, but rather a lack of cool days. Very similar to the situation in the US.

The number of stations has increased quite a bit, and the average latitude has moved towards the equator by more than two degrees, which probably accounts for the entire warming trend since 1955.  This is the sort of garbage in the GHCN record which makes the global temperature record meaningless.

    “Over the period 1960-2009 there is a spatially consistent warming trend in summer over France and a clear trend to fewer cool nights and more warm nights, and also to fewer cool days and more hot days. The warming trend for summer is 0.35 °C per decade (5th to 95th percentile of slopes: 0.24 to 0.48 °C per decade) and for winter 0.20 °C per decade (5th to 95th percentile of slopes: -0.02 to 0.40 °C per decade) (1).”

      I posted the actual data with an explanation that the average latitude is moving towards the equator.

        Sacre bleu! Throw in a little UHI, and voila! No warming at all.

          Siècle des Lumières!

          The warmunists made the French hot on paper and Tony Heller cooled them again.

          L’âge de la raison!

        ”The number of stations has increased quite a bit, and the average latitude has moved towards the equator by more than two degrees …”

        I made a similar observation some years back. The average temperature of the room increases when I take more measurements closer to the wood stove.

        I was able to objectively demonstrate that the room was hotter than previous measurements have shown. It made everyone happier on cold days.

          Without any gridding, that would be bad science and makes things look warmer. Similarly, anyone who takes a simple average of all stations in France (or any other arbitrary boundary, including the entire globe) must be very new or misinformed as to how temperature averages are derived.

          Does not matter how many recordings are to the north or south, assuming you do this properly. Take a simple average and the results are garbage.

      Looking at that first graph, its obvious why you choose the 1960 starting point

      You make a FOOL of yourself every time you post. Koont !!

      And then ignore that even that trend is mostly because of latitude movement and urban heat.

      I wonder if the French temperature sites are as absolutely woeful as many American and other sites around the world.

    Anyone who says there’s no research taking place on this blog is not paying attention. Anyone can go out and get the raw data; it takes talent to synthesize/interpret it and advance the science. This is true in many areas… social sciences, history, economics, and physical science. In a few simple graphs you’ve destroyed or called into question an entire metanarrative

  3. Gator says:

    2 degrees is roughly 140 miles, and France is less than 600 miles from north to south. That’s a ‘uge jump!

    I’m fearful that the white flag factories will burn down from global warming induced wildfires.

    Of all the French stations, count how many had an increasing trend vs how many had a declining trend. Would that eliminate the station latitude as influencing the trend?

    Also, it might be interesting to look at how many rural stations are trending up vs trending down and how many urban city stations are trending up vs trending down. I’m not a statistician, but I think you can set up a chi square using the counts, something like

    urban rural
    trend up 80 30
    trend down 10 90

    Then you’d be able to say there is a statistically significant difference in trends between urban and rural stations that maybe could account for the sustained lack of cool days, or rising averages if the minimum temperatures never fall because heat retained in urban areas?

      • MG says:

        Yes, well apparently Pierre and his dad figured it out, that’s great. Oddly, there is a wikipedia reference attached to the video telling you global warming is real. I guess that is part of youtube’s new “fact checking.” Also, the next video in the queue is “Urban Heat Island Crock.”

        • Gator says:

          Global warming is real, intelligent people call it an “interglacial”.

          As for those who don’t know that UHI is real and highly significant, they are in the same category as Flat Earthers and those that deny moon landings.

    Tony, can you post the trend for Chinese stations?

    The Chinese Met Office stated no warming from 1997-2017, while Nasa claims there was warming for Chinese stations in this time period. I would like to show the real deniers that there is no settled science as Chinese Met Office shows otherwise in their recordings.

    It would be nice to see how Germany stacks up under this sort of data scrutiny.

    Its a socialist wonderland, with some of the most rabid AGWer around.. ie Potsdam etc.

    Good Morning.

    Where I can found the data of the first graphic ?
    I live in France.

    Thank you very much !
