I wonder why they specifically picked 22 years, as opposed to 25 or 20.

This section of the article answers that:

> Williams was part of a team that published a similar study in 2020. At the time, they found the drought since 2000 was the second-worst after the late 1500s megadrought. With widespread heat and dryness over the past two years, the current drought has passed that extreme mark.

So when they first looked, it was the year 2020 and they looked at the period between year 2000 and 2020. And now they are looking at that plus the additional 2 years that has passed since last time they looked.
