To recap my opinions: which way to decide this is a matter of interpretation; either way is defensible; overall I'm inclined to agree with the majority.
The Agency ultimately projected, for instance, that it would be feasible to have coal provide 27% of national electricity generation by 2030, down from 38% in 2014
The judgement doesn't make much of this, but I would: the much-vaunted plan was shite to begin with. It aimed to get coal down to 27% by 2030. And by 2022, without the plan in place, coal is... 22%. So what was all the fuss about? The plan was totally pointless. The idiot govt should just stop this nonsense.
Absurd US Supreme Court decision leaves climate leadership in limbo?
From a twit by Mann, this piece by Trenberth, who really should know better. But, as roughly typical of that-kind-of-viewpoint, worth a breakdown. Calling the decision absurd is just wrong. KT leads with "As an expert on the science of climate change..." but hasn't realised that is irrelevant; the science wasn't an issue, as it wasn't in Alsup. He then mixes it up with "The decision is designed to tie the hands of EPA scientists to fight pollution and to protect air, water and our families from the climate crisis" but that isn't really true either. The EPA retains all those "ordinary" powers; what it doesn't get it power to regulate CO2, unless congress clearly states that it should.
