According to NASA, 1913 was one of the coldest years ever, with very low levels of CO2.
That very cold year brought the hottest (official) temperature ever recorded on Earth, 134 degrees in California.
On this date in 1913, the US had 100 degree weather from California to New Jersey, and from Texas to North Dakota. Oklahoma City was 111 degrees. Numerous locations in Illinois and Indiana were 108 degrees. Arkansas, Arizona, California, Iowa, Illinois, Indiana, Kansas, Kentucky, Maryland, Michigan, Missouri, North Dakota, Nebraska, New Jersey, Ohio, Oklahoma, South Dakota, Tennessee, Texas, Wisconsin, and West Virginia all recorded temperatures over 100 F on that date.
Weather this hot is inconceivable now, so climate alarmists instead use the heat index, climate models, and simply lie about the climate at every opportunity.
