Not only are heatwaves becoming less intense and less frequent in Missouri, but they are also starting later. Lebanon, Missouri has had seventy-five May/June days over 100 degrees since 1885. All but four of those days came with CO2 below 350 ppm CO2.
May 31, 1934 reached 101 degrees in Lebanon – almost a month earlier than the first 100 degree day in 2012.
People who are attempting to link CO2 and heatwaves in the US, are either incompetent or dishonest.
