Winter Advisory

The rate of infectious respiratory disease and deaths goes up in the winter.

Death rates are 10 percent or more higher in the winter compared to summer, respiratory illness/pneumonia/flu all are higher in winter.
Surely cold weather causes more stress than hot weather, and acclimation prevents heat stress and illness. Heat deaths are more problematic in the higher latitudes and are directly detrimental to the already debilitated living in substandard non air conditioned housing. The American South does not suffer heat wave deaths like the north, where acclimation to heat is not as well developed. There is also a very well proven phenomenon that heat deaths harvest from a vulnerable population so there is no tail of elevated death rates, but cold wave deaths have an impact and a tail so the total of deaths is net higher.
Warm is good for living things, that’s a no brainer, and this article about fog and cold dances around with advice, but most important is cold is harder on organ systems.

One might reasonably inquire on how the IPCC has come up with all these predictions of net harm to the human race from a rise in temperature well within the daily variation in temperature.
If the average temperature of the earth, at about 57 F is not comfortable and can produce cold injury, like chillblains, and stress on general well being, what would the “ideal” planet average temperature?
