Following the explosive growth in the use of coal for industrial processes, in which the UK from the late 1800s to the mid-1900s was memorably darkened with soot, the public became aware of "pollution". Black carbon, nitrides, sulfides, heavy metals, volatile organic compounds, chloro / fluorocarbons, pesticides, toxic waste, and spent nuclear fuel were on the list of industrial products that would become "pollution" if not handled properly... and it was quite often that they were not handled properly.
Now, the expression "carbon pollution" is being put into headlines by the Sierra Club, the Environmental Defense Fund, Harvard University, and even the Associated Press (via MarketWatch). None of these sources are talking about black carbon, hydrocarbons, or CFCs: "carbon pollution" means carbon dioxide.
Is it true that carbon dioxide is pollution?
