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

December 6, 2022

That’s a question I’ve been asking over the past couple of months.
===============

Today, let’s update the analysis that I’ve been reporting …

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

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

Then, I started looking harder at my monthly electricity bills from BGE (Baltimore Gas & Electric).

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

We previously reported in the past couple of months that year-to-date temperatures in the Baltimore area have been a couple of degrees colder than those in the prior couple of years.

Well, I just got my November bill and guess what.

The 8 month run of colder average monthly temperatures (versus last year) was finally broken.….

The average November temperature in Baltimore this year was 49 degrees …  3 degrees hotter than last year’s 46 degrees.

But, the November temp this year (49 degrees)  was still 3 degrees  colder than November 2 years ago (52 degrees) … and, the 11 month average (January to November) for 2022 was still 2.4 degrees colder than 2021 …. and 3.1 degrees colder than 2020.

Hmmm.

==============

Previously, I challenged readers to square this circle:

  • If the data shows that my average   local temperatures have dropped about 3 degrees from 2 years ago (and one year ago) — why should I believe (with “settled science certainty”) that the earth will be a degree or two hotter 50 or 100 years from now if I keep driving my SUV?

A reader offered up a simple explanation: 2020 and 2021 were historically hot years … and, if I looked deeper in history I’d see that 2022 temperatures are consistent with a warming trend.

That prompted me to do some further digging.

I’ll present my findings in a subsequent post…
