It's a double edged sword, though: deference to an administration that's not interested in the climate fight also undermines the fight.
Really this should be about making Congress fix broken laws.
You say experts, but that overlooks that these are political agencies, so it is really letting politicians in the executive branch interpret the laws outside of the democratic process in the legislative branch.
That's a very important thing to keep in mind when talking about this deference, and it's a huge reason to be skeptical of it.
@volkris Well yes and no, #Chevron is about deference to the agencies, allowing experts to interpret the laws and any vagueries in them
