Cognitive dissonance is two headlines days apart:

Today was the warmest day on earth in 125,000 years.

Today was the day with the most planes in the air at one time ever in history.

The rise of private planes as there is little regulation. Can take off and land any time day or night. Doesn't have the same emissions standards so the cheapest dirtest fuel is used. Lower maintenance requirements. And lower training standards for pilots.
Private airports are at or near capacity.
