Declining June 19 Temperatures In The US

June 19 used to be a hot day in the US prior to 1960, but temperatures have declined sharply over the past century. The five hottest June 19ths in the US were 1933, 1931 1910, 1936 and 1988 – the year Hansen predicted an increase in heatwaves before Congress.

On this date in 1933, most of the US was over 90 degrees, and a large percentage was over 100 degrees. New Ulm, Minnesota was 102 degrees, twenty-seven degrees warmer than today’s forecast maximum.

This week in 1988, James Hansen gave his testimony to Congress and said he was 99% certain the heat was caused by CO2 and said temperatures would get much hotter. That was the last really hot June 19 in the US.

The New York Times was (of course) very happy to assist Hansen in his scam, saying that the cooling trend was a “long expected warming trend.”

Ten years earlier, the same New York Times said there was “no end in sight to the 30 year cooling trend”

Global warming is mass superstition, hysteria and fraud, driven by fake scientists, fake journalists and fake politicians. If Donald Trump is going to drain the swamp, he needs to remove the criminals behind the global warming scam.

    With that vast tropical disturbance in the gulf coming on, a significant portion of the gulf coast somewhere is going to get a lot of cooling rain late this week. They really have no idea which way it’s going to turn yet but no matter if it heads for TX or the panhandle of FL it’s bringing massive rainfall with it.

      I started college at ASU in 1974, and Phoenix had 18 consecutive days over 110F – their all-time record. That was the peak year of the ice age scare.
      California was 134 degrees in 1913.

        I decided to follow in your footsteps and headed up to Arapaho pass. It was too cold and windy to make it all the way to the top but it was beautiful nonetheless. There is still a lot of snow there. Saw one couple getting a few turns on skis.

        Anyway, interannual variability is much larger than any trend over the past century. Statistically, one can not really say there is a trend with a high degree of confidence.

      Nothing unusual at all about it being hot in southwest US during the summer. But far be it for Griff to understand the difference between weather and climate. A single summer heat wave is climate change to her.

      Thanks for the weather report Ms Griff! Spotted any more imaginary ice breakers? LOL

      Why do you hate poor brown people Ms Griff?

      Thanks for the reputable source Griff… I learned a lot about the Kardashians and finally discovered what Hollywood stars look like without makeup. Yay SCIENCE!

    And look here…no more drought!

    (What ever happened to the endless drought, Griff?).

    Record high temperatures still standing for downtown Los Angeles, for the month of June – all of which would have been prior to any statistically meaningful AGW:

      There were no significant numbers of air conditioners prior to the 1950’s to inflate temperature readings in the summer, making this even more impressive.

      • garyh845 says:

        Indeed – urban heat island effect. For the summer months of June through July, there are still 25 high temperature records standing which were set prior to 1900; that’s 25 out of 92 days. Back then, there was no urban heat island effect for Los Angeles.

        • Cam says:

          Don’t you know those early temperatures can’t be trusted? That’s why NOAA keeps adjusting them down and more recent temperatures up. You’ve got to keep the meme consistent.

        • garyh845 says:

          Correction – I meant June – August (92 days).

      • Brad says:

        Or pavement

      • Windsong says:

        Pavement for sure. An easy comparison is the USHCN site at Spokane Intl Airport and the USCRN site at Turnbull NWR, 17 miles south, and at approximately same elevation. This morning’s (June 19) low at the historical site surrounded by acres of pavement: 61F. Today’s low at the state-of-the-art site unaffected by buildings and pavement: 45F.

        The numerical gap is obvious, but the primary problem is airport runway/ramp temperature is preserved as the area’s “record” in the USHCN.

        • R. Shearer says:

          Plus jet engine exhausts didn’t “take off” until the early to mid 1950’s. All in all, the adjustments being made to the temperature record are a farce.

    • Donna K. Becker says:

      I don’t remember the exact hear, but it once hit 113F in downtown L.A., and that thermometer broke!

      That was within approximately the last 15-20 years.

      • Neckbeard93 says:

        That actually did happen! It was on September 27, 2010.

      • garyh845 says:

        One should assume that 4-8 degrees, F, of that, would be from the urban heat island effect. The rest of it would have been because of a high pressure ridge creating the additional heat.

  4. Rah says:

    Meanwhile in my piece of central Indiana the average high for today is 81 deg. F. But the AccuWeather forecast high is only 77 deg. F. The sky is falling and we’re all doomed! The climate is changing!

  5. Gator69 says:

    CO2 is an “artificial gas”? So before humans started burning fossil fuels, there was no CO2?

  6. Timothy Anderson says:

    It is indeed a beautiful day in New Ulm, Minnesota, 72 degrees and sunny. Actually a bit cool for our visitors from Arizona.

  7. Neckbeard93 says:

    Hey, Tony! Love the site. Out here in North Carolina, our once-skeptical-turned-alarmist meteorologist, Greg Fishel, keeps talking about how summers have gotten much warmer in the Triangle area. Could you evaluate the veracity of this claim with GHCN data for average summer temperatures in Chapel Hill? I saw that there was a Chapel Hill station in the network.
