Air Pollution to get a lot worse, thanks to further fossil fuel combustion.

Hat tip to dtlange at Robertscribbler.

"Just as FF carbon GHG emissions continue unabated so do particulate aerosols." -- dtlange.  The increase in aerosols will contribute to global dimming, causing the impact of increasing CO2 atmospheric content to be less than it would be otherwise if there were no such aerosol increase. Which means the temperature increase will be delayed. And the more the temperature increase is delayed, making the spike that much bigger when the FF emissions finally do cease. Faustian bargain!

CLIMATE CHANGE: Study says air pollution will get worse.

Study by UCR professor says changing weather patterns will worsen fine-particle air pollution.

Climate change could make the world’s air even dirtier than it is now, according to an analysis by UC Riverside climatologist Robert Allen recently published in the journal Nature Climate Change.  Allen used NASA’s super computers to model how global warming changes the atmosphere’s ability to cleanse itself from fine particle pollution — the airborne soot, chemical compounds, dust, and other microscopic specks associated with an array of health problems. The study found that by 2100, such pollution, also called aerosols, would linger longer and build up in the skies above much of the United States, Europe and Asia.  “All of the models show more of a burden of aerosol pollution,” said Allen, an assistant professor in UCR’s Department of Earth Sciences. “All of the models showed a consistent increase.”
