That's the ecological fallacy, or mereological fallacy more broadly.
What's being described with global mean temperature is not the temperature of any region, weather event, etc. A 2C warming can be a +10C in one region and a -5C in another.
The magnitude global mean temperature rise does not imply anything in particular about "summers" or anything of the kind.
