This is a classic illustration of how Climate Change Panic Mongers conflate air pollution with CO2 emission. The US has had laws against pollution for 50 years. A lot of progress has been made cleaning up the air and water and in remediating toxic waste sites. Pollutants cause definite harm and everyone is against them. But CO2 is not a pollutant: it is what we breathe out and what plants breathe in. Trying to blame CO2 emission for deaths that should be attributed to smog pollution is intellectually dishonest and just a cheap way to scare people.
