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.
Tains 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 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.)
Actually, your theory hits the mark pretty well (and is not unknown). It’s a well known fact that particulates in the atmosphere prevent some sunlight from hitting the earth, thereby reducing temperatures.
I believe that England used to have far colder winters during the industrial revolution than it does now, because of all the pollution from burning coal back then.
The scientists refer to that as the aerosol effect; they haven’t decided whether is a negative or positive effect overall but it is not part of the models being used.
