Islip, Ithaca, Toledo, Dubuque...
Also claim they have 100 regional aircraft grounded due to pilot shortage.
I'm sure the Biden recession isn't helping.

Lack of contrails makes it warmer, not cooler. Interesting enough is that the theory was proven after all commercial flights were grounded for 3 days after 9/11. The average temperature increased 2C.
The average range difference between night and day temperatures was 2 degrees. Not the same. This article has a somewhat rambling explanation which could be clearer: https://globalnews.ca/news/2934513/empty-skies-after-911-set-the-stage-for-an-unlikely-climate-change-experiment/. And the theory that contrails have a warming effect has also been challenged: https://www.bbc.co.uk/blogs/climatechange/2009/05/911_contrails_study_challenged.html. His links are bad and the Beeb is suspect anyway, but it is true that three days in a relatively small part of the world is a very small sample. However, we have had less air traffic over a bigger area for months and we may be poised to get a better answer. This would be some real data for climate fans. I was only commenting that the skies are definitely cleaner and bluer, though. Regardless of the effect of contrails, I blame planes most for the horizon smudge that has been increasing for years.
