Des Moines has had only one 100 degree day during the last nine years, but in 1934 they had 31 days over 100 degrees, including three days in May.
It reached 101 on June 27 this year, and alarmists went hysterical. One hundred degree days used to happen on a regular basis in Des Moines. Now they are extremely rare.
Alarmists blame CO2 for heatwaves, because they are ignorant of history and science.
