There was an intensive study done by a Danish scientist. His conclusion. Solar flare activity had more to do with global warming and cooling than anything man has done since solar flares have been recorded. Man was spewing out more CO2 during the coal age than during the oil age. Also, when Mt. St. Helens erupted. It spewed more CO2 than all the industry in the US for an entire year. Man made global warming is only something liberals push to get MORE CONTROL over our lives. It has nothing to do with the weather.
If we all used solar, wind, geothermal, and ocean wave power, they would claim the earth is getting too cool and we need to burn more fossil fuels.
I saw a study in the 1970's if I can find it in my old paperwork. It said too much asphalt paving for roads, not only in the US but around the world was contributing to higher surface temperatures in cities and developed areas. Cities back then averaged 3-5 degrees hotter than the surrounding countryside. With global development and more roads being paved with asphalt, in China, India, South America, Africa. The heat absorbed by black asphalt might hold more heat than CO2. No one is talking about that. One suggestion back then was use more concrete, and use more white shingles and roofs on buildings to reflect the heat back into space. Hmmmm, just white paint and shingles, and concete streets in cities instead of asphalt. Hmmm. Is it that simple, that a gradual change in road construction materials and lighter shingles on roofs would help? They also say that snow cover in the winter helps reflect some heat back. Well, white shingles, white, silver, or light covered roofs. White vehicles, concrete roads, etc. Hmm. No real cost for anyone really. Not like FORCED use of alternative fuels and hybirds that are not yet cost effective.
