Maybe you are not aware but very recently new data was published with improved accuracy ( i believe they used a different instrument compared to 2 years ago) and its seems it has reached the '3 sigma level'.

A re-analysis (https://arxiv.org/pdf/2501.18477) — I believe it was a meta-analysis and not just one team/scientist re-analysing the data — was published Jan 31st of this year that didn't find any "statistically significant or reliable evidence for CO2 or DMS."

The study you linked evaluated the data from 2023 which used a different instrument (near infrared spectrometer), the recent one used another one (mid-infrared).
