re: Controlling pollution results in …Global Warming

This is like a drop in the bucket compared to what the Clean Air Act Amendments of 1990 did to emissions from coal fired power plants.

Scrubbers were retrofitted on many existing plants, and many others switched from high sulfur to low sulfur coal to reduce SO2 emissions.

Since that time, now 30 years later, numerous coal fired plants have been shut down, reducing emissions even further.

SO2 emissions from ships is like a fart in the wind compared to what has already happened.

So if the study is true, it started getting worse decades ago.

Anthropogenic emissions have negligible impact on climate change. FACT. Just look at the data, not the fear porn spread by our government overlords, media, and those institutions and people who make a living from our government overlords.
