WRT :[2007 Supreme Court case in which the court ruled that greenhouse gases are “air pollutants”]
The USSC has/had no authority, nor sufficient expertise to make such a scientifically bogus ruling!
For instance, the most abundant “greenhouse gas” (94%) is WATER VAPOR!!!
There are multiple problem with both your quote and your statement.
The USSC never ruled Carbon dioxide was a pollutant. The EPA got too cute and the USSC called them on it. Claiming that it was a pollutant but not needing to regulate it was what was declared wrong. The EPA were told to rule the carbon dioxide was or was not a pollutant, then regulate accordingly.
