We've spent a century+ pretending carbon pollution has no cost, and the entire history of capitalism -- if not our species -- pretending all other pollutions had no cost right up until that cost was undeniable.

So, not surprising that we're treating CO2 the exact same way. Only this time around, the polluters realized they could get ahead of the issue and convince enough of the general population that carbon pollution is harmless to prevent it from becoming publicly undeniable.
