Climate Independence Day

The US has had some some July 4ths, but none hotter than July 4, 1911. Thirty states were over 100 degrees, and all but one (Rhode Island) was over 90F.

This graph shows the maximum temperature in each state on July 4th, 1911.

These 12 states had their hottest July 4th on that day : Indiana, Maine, Massachusetts, Michigan, Missouri, New Hampshire, New York, Pennsylvania, Tennessee, Vermont, West Virginia, and Wisconsin. It was 104F at Boston, and dozens of people died in the heat.

There was also a 70 day long heatwave in Paris that summer which killed more than 40,000 people.  Compared to no reported heatwave related deaths in France this year.

Another very hot July 4 was in 1936. Illinois, Iowa, Nebraska, North Dakota and South Dakota had their hottest July 4ths on that date.

The heat was more intense in 1936 than 1911, with six states over 110F, and twenty-one states over 100F.

Alaska was hot on July 4th. 1936 – with Nome reaching 84 degrees.

Lots of people also blew themselves up with fireworks that day.

Nome has only exceeded that temperature only once, on August 1, 1977.

There was a huge high pressure ridge over the western US in 1977, which brought record warmth and drought to the west, and record cold to the east.

It snowed in Miami that year, and Alaska was warmer than Florida.

DENVER, Feb. 21, 1977  — A group of solar physicists and climatologists told a national science convention today that the bizarre weather of the last year might have been caused in part by abnormal activity on the surface of the sun.

the scientists said that all available evidence pointed to another year or two of cold winters in the Eastern and Central states and drought in the Western United States.

And it isn’t just on July 4th.  According to the National Climate Assessment, the intensity and duration of heatwaves has plummeted in the US.

    I went to A-Basin today. Nice snow for the 4th of July, but boy was it crowded.

    • Colorado Wellington says:

      Parisians escaping the heat and the banlieues?

      America! It doesn’t suck!

      • R Shearer says:

        Probably mostly Denverites and 99.9% driving fossil fueled vehicles. A mix of young and old (that should know better – like myself). I booked out after one run and the line of cars still coming in stretched from A-Basin to almost Loveland.

        I should have gone last weekend but due to global warming when will I have an opportunity to ski in Colorado on July 4th again?

        • Colorado Wellington says:

          I skied there after the Fourth of July before but I don’t remember the year. The history books say they were open till August 10 in the summer of 1995 so it was probably then.

          I was not around Arapahoe Basin or Arapahoe East in the good old days when Larry Jump and Dick Durrance reminisced about the good old days on the mountain.

          Frequent visitors to Arapahoe East were the Denver Playboy Club bunnies. One of our instructors, Mike Stevenson, was married to a Denver bunny. I remember many parties after the slopes closed at 9:00 pm with several bunnies in attendance.
          Larry Jump and Dick Durrance would join the socialization, and reminisce about how the sport was in ‘the good old days,’ as in 1930’s and 40’s.”

    Decades ago, I used to attend the July 4th “Slush Cup” at Mount Baker.
    Lots of fun.
    But it always had old snow in early July.
    I think it holds the record for a ski area for total fall in one year.
    Around 1,000 inches.

  3. Bob Hoye says:

    Looked it up.
    1140 inches or 95 feet.
    Season 1998 to 1999.
    A world’s record.
    Typical is around 650 inches.

    Right at the end of “Salute to America” california couldn’t take it any more and they had a 6.4 mag. earthquake. Gotta love it.

  5. Gamecock says:

    A climate change emergency! OH NOES!

    Well how do I know if I have climate change here? How do you measure it? How will we know when the emergency has passed? How can you tell when it goes from climate change to climate change emergency?

    “911. What is your emergency?”

    “Climate change.”


    • Colorado Wellington says:

      “Climate change is one of the greatest threats to health America has ever faced.”

      No doubt.

      “911. What is your emergency?”

      “Climate change.”


      “My next door neighbor is suffering a climate change attack again. He’s swinging a hoe at passing cars. He just hit a Subaru on the rear fender!”

      “What’s your name and address? We will dispatch Boulder PD, paramedics and a counselor.”

    • Jason Calley says:

      Hey Gamecock! “Well how do I know if I have climate change here?”

      Do you live in the US? Yes? Then it is simple! From
      we have this: “For the entire United States, excluding Hawaii and Alaska, the [annual average temperature] is 52.7 °F (11.5 °C).”

      Simply put a thermometer outside your home, maybe in the middle of your driveway, or near your barbecue grill where you can keep an eye on it. Anytime it reads more than 52.7 F, you are experiencing climate change. If the overage is greater than 2.0 F then you are experiencing mass extinction. Greater than a 4.0 F difference? That is runaway Venusian planetary death syndrome.

      Any reading lower than 52.7 F (unlikely!) is weather.

  6. Robert Forest says:

    Looks like the beginning of a marketing campaign to convince the public that oil companies can design and produce carbon light fuels that release less carbon. The plan is to attach increased management remuneration to the development of “lite” fuels. We already have “lite” fuels. They produce less energy. Looks like a plan to sell less energy for more money and give the increased income to the company management to reward them for their heroism. The propaganda begins.
