Dave sss, NOAA NCEI's Deke Arndt wrote about how generally cooler places are warming faster than warmer places. Arndt explained it in an essay published in 2015 on a NOAA page on the internet at climate.gov on a blog by the US' s official climate record keepers.
here's the start:
"This week, Beyond the Data looks at one of the more well-grounded “rules of thumb” for understanding climate change. This one is pretty simple to put your thumb on: on average, cooler places and cooler times are warming more quickly than warmer places and times.
"But first, let’s clarify–and emphasize–what we mean by a “rule of thumb.” Just like in its common usage, a rule of thumb here refers to something generally true often enough to be useful and informative, but not universally reliable–kind of a “two-out-of-three” or “three-out-of-four” kind of situation.
"So, it's nothing to thumb your nose at, because it’s true more often than not. But it’s also not the case everywhere. Local exceptions to the rule may be in the minority, but they don’t completely stick out like a sore thumb because in certain local situations, the facts can be … wait for it … opposable.
"With that definition and some horrible puns out of the way, let’s thumb through some data.
"Colder places are warming faster than warmer places
"This rule of thumb is really dominated by the fact that the arctic is the fastest-warming large region on the planet. The Arctic is warming at more than twice the rate of the rest of the world. This “Arctic amplification” is driven by a handful of factors; the largest of these is the retreat of seasonal snow and ice. As the white stuff goes away, it exposes darker surfaces and land cover underneath; this introduces an additional warming effect across the region."
