.................. The net effect of all these direct and indirect factors is a cooling by aerosols, which has partially offset the warming by greenhouse gases. ...........
“I ain’t be no scientist, but when I looks into a hazy air downwind from a belching power plant, I don’t need no hat;
Yet, when after it rains, and da sun shines, I needs ma hat ‘cause the sun be stronger an’ warmer!
I don’t know what counts as the fancy named “aerosols”
But, I’d like to repost my response to an earlier Global Warming FR thread:
............................................
I BELIEVE THAT MAN IS RESPONSIBLE FOR WARMING OF THE GLOBE!
But, not as you might think.
I hear abour sun cycles, and that is proper!
But think about recent mankind’s influence on the amount of sunlight hitting the surface of the earth.
In past decades man heated homes with wood, peat, coal - all spewing their particulates into the air... Today #2 oil and natural gas are high efficiency clean fuels.
Trains and boats spewed their coal fired effluents into the air, with huge pollution. Today, these are all highly efficient diesel electric engines.
Up to the 1950’s all metal working industries relyed on the coke fueled cupola to melt metal, belching millions of tons of particulates in the air. Today, these are all electric furnaces, and whatever industrial smokestacks exist, they are all fitted with scrubbers to eliminate particulates in the air.
Today’s automobile spews 5% of noxious gases as compared to 1970’s lead gassed autos before the catalytic converter.

Yes, I believe that mankind has caused the planet to warm in the past fifty years.
Not because of harmless carbon dioxide, but because of our highly successful efforts to clean up the atmosphere, which now allows so much more of the sun’s energy to warm the surface of the earth.
(I’ve never seen a scientist espouse my theory of air cleanliness creating more solar warmth, but I truly believe that industrial mankind’s efforts to clean our atmosphere are resulting in the warming or our planet.)

??So, what are these scientific “aerosols”??
Does letting more sunlight get through the atmosphere cause more sunburn, and more ground warming???
Many studies show that over the past 50 years or so, less sunlight has been getting to earth - see global dimming. Aerosols, soot and dust have been blamed, particularly that injected into the upper atmosphere by commercial jet travel.
