2023 has been a hot year… We have the makings of a super-El Niño and an unprecedented injection of water vapor into the upper atmosphere stacked on top of a general warming trend since 1978, if not since the nadir of the Little Ice Age. So, it should come as no surprise that we have seen satellite-era record high temperatures, this summer and early fall.

As a geologist, I always have to apply scale and context to everything.

Scale

Temperature anomaly records are great tools. They are the only way to accurately describe how global temperatures are changing over time. However, they lack scale. They lack a frame of reference.

It is a common adage that when a geologist takes a photograph of a person, that person is simply there for scale. Other scale references include: camera lens covers (rendered obsolete by smart phones), quarters, rock hammers, spouses and action figures (on April Fools Day only). The key is to come up with a reference that is relatable. And what temperature reference is more relatable than a thermometer?
