  •  SO2 vs CO2 (9+ / 0-)

    Whilst I certainly hope this bodes well for the ability of the EPA to regulate suicidal emissions like CO2, I would like to point out that SO2 is both a greenhouse gas and individually immediately toxic to humans.

    It might be a tougher sell to get the more scientifically illiterate members of the court to understand the greater long-term threat of less toxic CO2.

    •  Actually they already ruled on that (5+ / 0-)

      In Massachusetts v EPA.  Basically, the clean site act authorizes the EPA to regulate GHGs.  SO2 has been regulated under the CAA for years though

    •  To be fair, those levels are very low (2+ / 0-)

      There are no measurable health effects of SO2 exposures at twice the NAAQS. As for the greenhouse gas effects, it's not entirely clear. Yes the ground-level ozone and particulate matter emissions are raising temperatures, but the sulfate particles  higher-level atmosphere is believed to be reflecting some sunlight and actually holding down temperatures below what would be expected given the warming potential of other greenhouse gases already in the atmosphere.

      •  CO2 vs SO2 (0+ / 0-)

        Yes, there are more deadly things than SO2, but the highest NAAQS for SO2 is 0.5 PPM and the average CO2 concentration in all the air we breathe is about 400 PPM.

        You're right, SO2 is not a greenhouse gas, it's actually the opposite.  I don't know what I was thinking.  I thought I did my due-diligence, but apparently, I did not!

        The Reuters source article seems to be conflating acid rain and respiratory effects in SO2 with global warming effects in CO2.  Maybe they were just trying to indicate the court has found once more that the EPA has the power to regulate the air part of the environment... like that should be news...
