About that tropical "hot spot"

A couple of days ago I wrote about the new paper by Steven Sherwood and Nidhi Nishant, which was reporting the release of an updated radiosonde dataset, and findings from an analysis of those data.
Data sources: Scripps and GISS/NASA

One of the things the authors reported was the "tropospheric hot spot" - though they didn't use that term in the paper itself (only the press release). I've never previously thoroughly looked into this myself. I knew about it in general terms, because some deniers point to what they regard as lack of evidence as evidence that global warming isn't happening. Which is really, really weird when you think about it. Or when you look at surface temperature data as in the chart on the right.

Anyway, I decided to go and learn more about this so-called "tropospheric hot spot".
