I assume legal issues falls in EBF topic.
Global warming is by no means a settled issue, they made clear, suggesting it would be foolhardy to assume it was.
First and foremost, courts decide legal issues not matters of science. Remember in the Scopes trial, the court actually found against the evolutionary proponent!
as supported by the USSC's statements of finding in this very case!
..."It is altogether fitting that Congress designated an expert agency, here, EPA, as best suited to serve as primary regulator of greenhouse gas emissions. The expert agency is surely better equipped to do the job than individual district judges issuing ad hoc, case-by-case injunctions. Federal judges lack the scientific, economic, and technological resources an agency can utilize in coping with issues of this order. See generally Chevron U. S. A. Inc. v. Natural Resources Defense Council, Inc., 467 U. S. 837, 865–866 (1984). Judges may not commission scientific studies or convene groups of experts for advice, or issue rules under notice-and-comment procedures inviting input by any interested person, or seek the counsel of regulators in the States where the defendants are located. Rather, judges are confined by a record comprising the evidence the parties present..."
Beyond this, this case has nothing to do with whether or not issues of climate science are correct or incorrect, the court was called upon to rule whether or not the EPA had standing and authority to regulate CO2, and whether or not the various nuisance suits being filed by various state authorities could continue in an effort to avoid EPA regulations and standards, to which the USSC unanimously agreed that the EPA was acting properly and in accord with previous court directions and that there was no merit or basis in the various state challenges to EPA actions. And now you are going to try to cherry pick and distort the court's rulings into a big "win" for those that are trying to interfere with and stop all efforts to minimize humanity's forcings of the climate? Seriously?

Justice Ruth Bader Ginsburg wrote in the main opinion:
“The Court, endorses no particular view of the complicated issues related to carbon-dioxide emissions and climate change.”
The Court reinforced the legal conclusion that it had drawn back in 2007 in the case of Massachusetts v. EPA, stating that the EPA has been told by Congress to treat greenhouse gas emissions as an “air pollutant” under the Clean Air Act, and is obliged to do something about it.
The decision put a stop to a spreading series of lawsuits, that have been designed to attack not only global warming mitigation efforts but also various other perceived threats to the environment. All of the other ongoing and planned court challenges of EPA (and various endangered/protected species acts) regulation activities are covered by this decision and looks like it nips them off at the roots.
In looking through this ruling I just don't see what has inspired your jubilation, but if you care to point the exact terms, I will be happy to go back through the transcript and review the statements in their complete context, and comment upon them.
