Limits set by experts to mitigate global warming being broken to protect the public from the cold

Listening to NPR in New England during a winter storm and what has been several weeks of record cold temperatures one is struck by the irony that utilities had to drop using natural gas because its currently needed to heat homes and therefor they are  using dirtier oil fired systems which then break local state government clean air limits. So limits set by experts to mitigate global warming are being broken to protect the public from the cold. Let Mr. Market be the expert. Gas fired cleaner energy is generally cheaper and utilities are drawn to using it for pure economic reasons and when the cold and spike in gas prices subsides to normal they will use it again without need of an expert looking over their shoulder telling them to do so.
