Update: If the earth is warming, why isn’t Baltimore?

September 6, 2022

I hate to impair a popular narrative with actual data, but…
=============

Like much of the U.S., the Baltimore area (where I live) was enduring an apparent heatwave this summer.

It was hot enough that, even I, momentarily thought: “Maybe the earth really is warming.”

Then, I got my monthly electricity bill from BGE (Baltimore Gas & Electric).

Besides usage info, BGE reports the average monthly temperature, for the current and prior years (the red boxes)

As Gomer Pyle would say, “surprise, Surprise, SURPRISE”.

The average August temperature this year (including the apparent heat wave) was 76 degrees … down 3 degrees from last year’s 79 degrees.

A fluke?

Note: According to BGE, my HVAC-driven usage was down 25% from last year.

Since we’ve kept our thermostat settings the same year-to-year, that’s consistent with a colder average temperature.

To dig deeper, I pulled some more historical data from my BGE file…

Below are the average monthly temperatures in Baltimore (as reported by BGE) for January to August in years 2020, 2021 and 2022

What does the data show?

  • Again, this year (Aug. 2022) was 3 degrees colder than Aug, 2021 and Aug. 2020
  • More broadly, comparing year-to-year temperature by month, all 2022 monthly temperatures were equal to or colder than  2020 temperatures
  • Compared to 2021,  only one month —  February 2022 — was hotter than the 2021 temperature (40 degrees to 36 degrees) … all other months in 2022 were colder than their comparable months in 2021.
  • The 2022 8-month average (January to August) was 2 degrees colder in July 2022 than it was in July 2021 …. and 3 degrees colder than it was in July 2020

My take

  • It’s conceivable that BGE’s data collection is wrong … or that Baltimore is a complete outlier that’s not representative of the rest of the earth …. but, I doubt either is true.
  • The data probably doesn’t indicate that the earth is cooling … but, it sure as heck doesn’t support a global warming narrative.

Somebody’s gotta explain to me:

  • if the data shows that my average   local temperatures have dropped almost  3 degrees from 2 years ago — why should I believe (with “settled science certainty”) that the earth will be a degree or two hotter 50 or a hundred years from now if I keep driving my SUV.

This circle doesn’t square…
