Letter: Time we took a serious look at solution to declining air quality

We just passed a milestone: 400 ppm of CO2, already past any safe level for our climate. It’s a far more serious threat to our way of life than the others that make the headlines. One of the effects is ocean acidification, which puts our fisheries at risk.

There is no real doubt about all this any more. A while back, even Richard Muller of Berkeley, probably the last holdout among serious climate scientists, changed his mind: He was funded by the Koch brothers to review the ground-level data, and now is no longer a skeptic.

Any solution should be taken seriously, and a revenue-neutral carbon fee is a pretty good one. Let’s look at supporting it.
