For his global maps he switches from a temperature percentiles chart to one comparing versus 1981-2010 averages. So he's not showing an apples to apples comparison. So the one he makes a fuss about seemingly not showing so much warming, and with larger cooler areas is, of course, the one where he is ignoring all the warming before the 1981-2010 average. So of course it shows relatively less apparent warming.
There is nothing surer than a Heller presentation being fraudulently misleading.
