surprise finding – air conditioning makes people cooler!

Global warming has been under way for at least 25 years, and there is strong evidence that it is largely man-made and is continuing.

In recent years, temperature and mortality data from several countries shows that cold-related deaths in each age group are falling in most countries. Much of that was due to rising climatic temperature and better home heating.

A surprising finding is that the heat-related mortality rate has stabilized or fallen, despite rising temperatures. Air conditioning has been a major factor in the United States.

Heat-related deaths there are lower among people with air conditioning. An extension of air conditioning was accompanied by the virtual disappearance of heat-related death in North Carolina, despite summers becoming hotter.
