From a Geologic point of view, we are just now coming out of a mini ice age (thank God), so the numbers are skewed towards a warming period. The world temperature has been much hotter at times, long before man ever walked on the earth. That is indisputable. So, the author is correct from a certain point of view - Heat waves ARE virtually impossible without Climate Change. This year and every year. And the sky is blue (at times), grass is green (at times), the lakes, rivers, and oceans are full (at times), etc. Reporters, however, are stupid almost all of the time. That is a fact.
