With December 2022 climate data rolling in, it’s time for the annual update to the climate trend graphics for Alaska and vicinity. I usually present spatial maps of Alaska climate change information over 50 years. I do that mostly because it’s a time range that is within a person’s (of a certain age) adult working memory. Also, it’s a round number and has a nice ring to it: “half century”. For time series, which typically serve a slight different purpose, I’ll use the full range of reliable data.
