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.

NOAA – 759 Low Max Records Broken or Tied in 3 Days – Feb 26 to Feb 28 2015

Ooops:  This post originally said “Low Min”. The values are “Low Max”.

759 Low Max Records Broken or tied in last 3 Days according to the NOAA.

Below is a screenshot showing location and the biggest difference between old record and new record.

The list is just the ones I could capture in a screenshot. Wow. Many records broken by over 20F.

Imagine … the old record was 51F and it is now 23F. A 28F difference.

Some of the records broken were over 100 years old.

NOAA – 2634 Low Max Records Broken or tied From 2015-02-19 to 2015-02-25

(This is a different post than the Low Min one)

Low Max records track the lowest maximum temperature for the day.

2634 Low Max Records Broken or tied From 2015-02-19 to 2015-02-25 according to the NOAA. (That is 15% of all the measurements for that period)

Below is a screenshot showing location and the biggest difference between old record and new record.

The list is just the ones I could capture in a screenshot. Wow. Many records broken by over 20F.

Imagine … the old record was 34 and it is now 3F. A 31F difference.
