I had so many arguments on reddit about this. People contorted themselves endlessly to explain it away. I think the excuse they settled on was that the function with the hardcoded array of modifiers was never actually called by any of the other code. ...okay, but see, we don't actually have all the code. Nor do we have the data. So my reply was, if climatologists want to regain people's trust, they need to release all their data and all their code and something like a make file so that anyone can download it, run make, and it would output every graph and table used in their papers. Of course, they wont do this.
