It's not a jump. They're both bad for the same reasons, they both burn methane and leak into the air before combustion even happens.

I didn't say there was not a such thing as a buffer zone, I said there's no buffer zone in the case of inversions in valleys. An inversion traps the gas in the lower levels because of the flipped temperature graident. Here's a picture of an inversion in the Wasatch Front:

Those are gasses. That's not fog. That is pollution. Pollution primarily from refineries and gas power plants, along side vehicles.

Kevin O'Leary is building a natural gas powered data center in this valley. Those gasses will get trapped. This discussion isn't necessarily about alternative fuels, it's about whether natural gas has harmful effects. It does, especially when it gets trapped in inversions. Yes, if he was building a data center with nuclear power, that would probably be ideal. But none of his data centers are doing that, and they're in places that suffer from inversions. He (and the natural gas companies) are going to get more people sick.
