Air Pollution Cuts in East Asia Likely Accelerated Global Warming. Really!

In recent months, there have been quite a few articles implying that the global loss of cloud cover and cleaner air is contributing to accelerated global warming.

Is it only acceleration or more like causality?

Maybe we should go back to less cleaner air and the global warming hoax/climate change religion will disappear! Caution: satire.

Notice again, these scientists want us to believe they can measure something as complex as global surface temperatures to a precision of a tenth or one hundreds degree Celsius (and they omit, as usual, the show the degree of uncertainty or measurement error) and compared to such temperatures in pre-industrial times . This is pretty absurd! A ridiculous pretense of knowledge! This is more charlatanry than science!

"The cleanup of air pollution in East Asia has accelerated global warming, a new study in the journal Communications Earth and Environment has found. That’s because some forms of air pollution in the atmosphere have helped shade the Earth’s surface from the sun’s energy. ..."

"... Aerosols have recently been assessed to have cooled the global surface by 0.4 °C (the year 2019, relative to pre-industrial conditions)"

"Global surface warming has accelerated since around 2010, relative to the preceding half century. This has coincided with East Asian efforts to reduce air pollution through restricted atmospheric aerosol and precursor emissions.

A direct link between the two has, however, not yet been established.

Here we show, using a large set of simulations from eight Earth System Models, how a time-evolving 75% reduction in East Asian sulfate emissions partially unmasks greenhouse gas-driven warming and influences the spatial pattern of surface temperature change.

We find a rapidly evolving global, annual mean warming of 0.07 ± 0.05 °C, sufficient to be a main driver of the uptick in global warming rate since 2010.

We also find North-Pacific warming and a top-of-atmosphere radiative imbalance that are qualitatively consistent with recent observations. East Asian aerosol cleanup is thus likely a key contributor to recent global warming acceleration and to Pacific warming trends."
