Experience how contrails impact the climate

One of the more recent papers in 2021 from that link seems to disprove the whole thing pretty convincingly by looking at temperature fluctuations during the Covid lull in global air traffic.

That's a paper from a single author-- an "independent scientist" in New Zealand. It's a "commentary" that doesn't require peer review. It also does not read at all like a scientific paper.

The author in question is actually a well-known crank: https://www.desmog.com/albert-parker/

Ok but what issues do you have with the argument itself / methodology?

After all, Feynman was also a bongo-playing womanizing crank and single author on multiple papers.

Sorry-- I can't read every paper by every known crank and debunk it. It's an unattainable goal. I would have to pull all the data and analyze it again myself.

If you have an author who has committed great methodological errors in data analysis multiple times in the past and this is a documented fact, you stop taking that person seriously.

Here, it shares a lot of characteristics with papers he's written in the past-- possible censoring of data (picking one country, and a dubious date range for the comparison series) and ignoring other well known effects related to the COVID shutdowns (reduction in particulate emissions causing a pop in daily temperatures).
