The question is how this overall warming effect is distributed.

E.g. assume it's 15 ºC average to begin with. We might approximate this as a sine wave over the year with an amplitude of 10 ºC.

In the case of 3 ºC warming, we might then have 18 ºC with the same 10 ºC amplitude sine wave, or we might have 18 ºC ± 20 ºC. These scenarios would be very different despite having the same average temperature.
