well until somebody does that analysis on hadcrut 4.4 I'm not sure you can say that the comment is:
incorrect - remains unproven
presumptive - remains possible
emotive - still irrelevant
bigoted - vexatious and tendentious
denial - still one adjective too many
I would say not only not civil enough in the circumstances, but typical of the alarmist bent to resort to condescension. An essential sign of fragility perhaps
