China's emissions policies are helping climate change but also creating a new problem for global warming/climate change

The sun, not anthropogenic CO2 is the dominant factor for warming and cooling on earth! How variable is the sun's output?

Air pollution prevents global warming! 😊

"China's sweeping efforts to clean up its air have delivered one of the biggest public health success stories of recent decades. Since the Air Pollution Prevention and Control Action Plan was launched in 2013, coal-fired power plants have been fitted with scrubbers, heavy industry has been modernized and pollution standards tightened, leading to an over 50% reduction in atmospheric particulate matter. ...

In the atmosphere, sulfur dioxide forms sulfate aerosols, tiny particles that reflect incoming solar radiation back into space, leading to a cooling influence on the planet.

The combined aerosol radiative forcing is thought to have offset approximately one-third of global warming caused by greenhouse gas emissions. However, as emissions fall, fewer sulfate aerosols form, meaning less sunlight is reflected and more solar radiation reaches Earth's surface, contributing to global warming. ..."

From the abstract:

"Anthropogenic emissions over China have recently declined due to environmental actions. This work estimates the sensitivity of sulfate aerosol (SO4) concentration to the amount of SO2  emissions reduction over China from 2010 to 2020 using an Earth system model with two different aerosol representations. We find that a larger rate of SO2  emissions decline over 2010–2020 from an updated Chinese emission inventory leads to improvement in modeled SO2  and SO4  concentrations when evaluated with targeted airborne observations from the Asian summer monsoon region from the 2022 Asian summer monsoon Chemical and Climate Impact Project. Updated Chinese SO2 emissions reduce SO4  concentration by >20% at 200 hPa over the North Pacific, and by >7% at 100 hPa throughout the tropics. These SO4  reductions result in an increase to global net instantaneous radiative forcing of ca. 0.10–0.15 W m-2  by 2020, with regional effects up to ca. 6 times greater."
