The fact that air pollution protections save lives (and thus dollars) has long been an inconvenient fact for those who want polluting industries unfettered.
This move is indefensible and dangerous.

Here's my latest piece for the @ucs.org blog. Today marks the longest period without a nuclear explosion since Trinity. I explore why as well as the reasons that it would be so counterproductive for the US to shatter this moratorium.
The Nuclear Testing Moratorium Passes a Milestone
The world has now gone the longest period of time since 1945 without an explosive nuclear test. Breaking this streak would be not only unnecessary but also unwise.
