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

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.



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…

    Prof Homa, Baltimore might have a micro climate, but if you really want to see impact of climate changes, kindly visit places where its impacting more. I was in Island in October and saw ski lifts first hand which is over 50 years, and locals told they have to abandon these because no snow for last ~5-8 years. Visit Alaska and you can see retreating glaciers. Visit my hometown in Himalaya’s ( I grew up, so no first hand). We can’t grow Lychee’s ( a fruit) anymore, which was the specialty of the region, because they rupture before ripening due to heat. We can’t dispute science.

    :-) just noticed Google Voice to text made few grammatical errors and I pressed without editing.
