Have I made the claim that it increases the frequency of occurrence? I feel that link is a red herring and obfuscates reality. What I, and all of the papers above, have been referring to is the frequency of intensity of storms. NOT the frequency of storms.

Other than the graphs I've already pasted, the phenomena shows up over and over again in the power dissipation index;

Here's yet another paper on the topic and its graphs;

First of all, the graph you linked to only mentions the frequency of occurrence. It does not include intensity. Second, I trust well sourced papers featuring replicable research by scientists published in notable peer-reviewed journals over random people on Twitter.
