The typical warmunists/radical left wing ecowacko response. “Nuh uh!”
I used to hear people complain about all the “smoke” rising from the stacks at the sawmill I worked at. They never seemed to notice that they didn’t see it during the heat of the summer days.
What they were seeing was steam from water baked out of the sawdust and woodchips we burned to heat the kiln building. It was burned and re-burned to get the most energy available out of the material as possible. It produced very little particulate matter and was filtered before leaving the stacks. What little ash was produced was sold to a company that made concrete.
