An observationally based energy balance for the Earth since 1950

Look Ma, no models.

.................. 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???

Thanks for posting.

Thanx !

Beam Me to Planet Gore !

2009: Coldest U.S. summer in recent history; 300 low-temp records set

That's too bad. Why not require excerpts?

"After accounting for the measured terms, the residual forcing between 1970 and 2000 due to direct and indirect forcing by aerosols as well as semidirect forcing from greenhouse gases and any unknown mechanism can be estimated as −1.1 ± 0.4 W m−2 (1σ). This is consistent with the Intergovernmental Panel on Climate Change's best estimates but rules out very large negative forcings from aerosol indirect effects. Further, the data imply an increase from the 1950s to the 1980s followed by constant or slightly declining aerosol forcing into the 1990s, consistent with estimates of trends in global sulfate emissions. An apparent increase in residual forcing in the late 1990s is discussed." Funny how this same time period coincides with the global movement to regulate and control such aerosols; so warming is still our fault -- even if we leave CO2 completely out of the equation.
