The July 1915 Heatwave At Yosemite National Park

During the week of July 19-25, 1915, afternoon temperatures at Yosemite National Park headquarters were over 110 degrees every day, averaged 112 degrees, and peaked at 115 degrees on July 20.

The only other year when Yosemite reached 110 degrees was a year earlier in 1914 – and in 1913, Death Valley, CA set the world’s record temperature of 134 degrees.

California was very hot when CO2 levels were low, but that certainly doesn’t stop climate scientists from lying about the non-existent relationship between heatwaves and atmospheric CO2.

    Well, it is a good thing that the type on a site does not smell.
    It is not difficult to see people like Doc defending the ridiculous remarks about TOBS, negative and positive adjustments are not convincing. They make remarks about Tony, but prove nothing. the kool-aid drinkers do well there. They do not see the merits of raw data because it disproves their religion. They do not see the benefit using continuous reporting stations because it disproves their religion. They think using only recent stations is great.
    It is the same as reading Unrealclimate.

    Last time I was at Yosemite I was backpacking with a mix of new an old acquaintances. One of my new friends was a professor from Berkeley, who loved to tell everyone how erudite he was. When we got to our back country campsite, he proceeded to strip naked and went for a swim, after hanging his clothes on the sign that read, “No Swimming – This is your drinking water”. I made a bee line to fill my canteens before his carcass polluted the entire reservoir.

    Interesting photo. Imagine if there was a weather station on the shaded right side of the valley, and then it got moved to the sunny left side.
