I'm not sure what point you're making. The changes in the climate will occur at both ends of the spectrum, and the range between the extremities will get wider and more pronounced, even in the same year.
If the range between the extremities increased more would die of heat and more of cold, wouldn’t they? So more would still be dieing of cold. At least for the foreseeable future.
Give it a week and the HDM will be carrying stories of how Hull is coping with the drop in temperature and asking what happened to the summer.
