In New York City, congestion pricing leads to marked drop in pollution

There was a study published about how much air pollution dropped in NYC during the COVID lockdown. PM2.5 was found to have dropped 36%. However with more robust analysis, this drop was discovered to not be statistically significant. I would caution anyone reading this who is tempted by confirmation bias.

We have fruit trees in our backyard. The year of the COVID lockdown they had so much fruit the branches broke from the weight. Most fruit I've seen in 20 years in the house, by a large margin.
