My colleagues and I quantified the potential air quality and health effects of two natural gas power plants proposed for southeastern Wisconsin.
Over their expected 30-year lifetimes, air quality damages could total $1.38 billion.

In the early 1930s the SA was roughing people up, creating chaos in neighborhoods, seeking to terrorize with the occasional killing. By the late 1930s it had been supplanted by the SS, which was much better trained.
Also, may I say that I don’t agree with people saying ICE and CBP need “more training.” They’re doing exactly what this administration has trained them to—impose a reign of fear in blue cities. They don’t need more training. They need to be ripped up root and branch.

The Trump administration is proposing to value the cost of air pollution deaths at $0.
It’s no wonder that Trump’s EPA would take this step: avoided premature mortality is regularly the largest category of monetized benefits used to justify Clean Air Act regulation.
