We do have lots of surface-level temperature and wind data. We just don't have a ton of high altitude data. And ultimately, it's the surface-level data that impacts us day-to-day - which indicates that yes, the surface becomes cold AF more frequently than before. Oh, and as an aside, recorded anecdotes are perfectly valid for use in science. Hence why we can even have science for psychology.
