USA Temperatures – Shrinking Population = Cooler / Growing Population = Warmer

A couple of years ago I posted an article about waste heat.

“The waste heat generated by car engines, power plants, home furnaces and other fossil fuel-burning machinery plays an unappreciated role in influencing regional climates, new computer simulations suggest. By altering atmospheric circulation, human-made heat may raise temperatures by as much as 1 degree Celsius during winter in the northernmost parts of the world.”

Compare this map of CRN temperature changes from a WUWT article to the population growth map.

A large part of the US is shrinking population-wise and that part of the USA is cooling.

Waste Heat Responsible For Most of Northern Hemisphere Warming
