Cleaner Air = More Sunshine

I found this paper on Google Scholar. But I can’t find a direct link anywhere that works.

But it is important so I will put up this post anyway.

 

Cleaner Air: Brightening the Pollution Perspective?

Colin O’Dowd, Darius Ceburnis, Aditya Vaishya S. Gerard Jennings & Eoin Moran

School of Physics & Centre for Climate and Air Pollution Studies, National University of Ireland Galway

“This study has demonstrated for the first time, using in-situ PM measurements,
that reducing aerosol pollution is driving the Insolation Brightening phenomenon and
that the trends in aerosol pollution, particularly for sulphate aerosol, is directly linked
to anthropogenic emissions. Ultimately, the analysis demonstrates that clean air

policies in developed regions such as Europe are driving brightening of the
atmosphere and increasing the amount of global radiation reaching the Earth’s surface.
The actual impact of cleaner air and insolation brightening on temperature remains to
be elucidated”

As I’ve said before, cleaner air may have warming the earth after 1975. Dirtier air after 2000 may have stopped the warming.

  1. It is ironic that environmentalist’s removal of sulphur from fuels has caused some of the warming along with natural ocean cycles. One is finally seeing that reversal being mentioned by the warming crowd as a reason for the stall in rising temps since 2000. China and others have raised the sulphur output and may inhibit raising temps as well as a colder PDO cycle in the Pacific. Global cooling when the Atlantic cools around 2020?

  3. Easy, tiger! You are presuming way too much here.

    It is IR leaving the earth’s surface that is subject to the greenhouse effect. More solar radiation reaching the surface will lead to more IR trapping as it exits and more heat.

    I would advise anyone to read the paper before jumping to hasty conclusions.

    • More sunshine = more energy reaching the surface. Quite simple.

      The AGW theory blaming CO2 requires the bizarre assumption that nothing else in the climate system has changed much. It appears this paper and others demolishes that.
