Sure. Too much oxygen to a newborn baby can cause blindness; oxygen in that case is a pollutant. Certainly, if an essential gas like oxygen can be classed as a pollutant, since too much carbon dioxide can be deadly as an acute poison, it’s fair to class it as a pollutant when it appears where it should not appear, or when it appears in concentrations too great to be safe for what we need it to do, or when it is destructive.
The tougher question is, can Congress do anything about it?
Arguments about whether carbon dioxide is a pollutant distract and detract from, and delay the critical arguments about how to act to mitigate harmful effects of climate change and how to prevent the most disastrous effects, if possible.
Barry Rabe teaches at the University of Michigan and studies policies of government on climate change, and the policy making of government on climate change.
Take a look at some of his work, under the title, “Can Congress Govern the Climate?”
