Now, they are coming for oil and gas development and manufacturing through the just - announced 626 - page ozone regulations, which will require states to dramatically
reduce ozone emissions from the current 75 parts per billion (ppb) to a range of 65 to 70 ppb — though environmental groups want a 60 ppb standard, which may be the final rule.
Signe goes along with that by admitting that it is uncertain whether the Montreal Protocol is the cause of
the reducing ozone hole.
The other explanation involved ozone but I pointed out to you that solar influences are paramount there and Signe goes along with that by admitting that it is uncertain whether the Montreal Protocol is the cause of
the reducing ozone hole.
This implies that efforts to improve rural electrification for instance — even if the power is generated in a modern coal power plant — could still reduce net climate warming because of the impacts on
reducing ozone, methane and black carbon.
