Global dimming mediates (dampens) the relationship between CO2 and global warming...
Hi. I was watching PBS and thought you’d like to know some of these thoughts…
This is very inconvenient. We like warring for oil and paying Islamic Princes. These activities drive our economic engine on the blood of our young poor. Sure, give another no-bid contract to Halliburton, its good for the economy, after all! Conservatives like to create a “wedge” or a “controversy” in issues where there is no controversy. They tried to do create a false controversy about evolution and they try to create a false controversy about global warming. Watch out: germ theory is next! After all, it’s just a “theory.”
Yet, many people will die due to global warming. All of Florida will be underwater in the next century. Our poor great grand-children!
However, global dimming mediates (dampens) the relationship between CO2 and global warming. So if we put tons of sulfur into the upper atmosphere, we’ll save Florida and the last of the ice caps, but we’ll create more draught over Africa due to global dimming’s effect on evaporation (much less evaporation).
It is the photons that due the evaporating, so if we dim out a lot of photons, it will get very humid but not rain. Icky-stick. Global dimming has increased pretty dramatically since the 50’s.
Now if you don’t think a degree or three rise in temps in 100 years is bad, you should see what effect that really has on land, people, drought, fires, and famine. Scientists predict that continued global warming on the order of 2.5°-10.4°F over the next 100 years (as projected in the IPCC's Third Assessment Report) is likely to result in a rise in sea level between 3.5 and 34.6 in. (9-88 cm), leading to more coastal erosion and flooding; severe stress on forests, alpine regions, and natural ecosystems; greater threats to human health as mosquitoes and other disease-carrying insects and rodents spread diseases over larger geographical regions; and the disruption of agriculture resulting in famine.
See PBS.org on global dimming.
Anyone for wind, solar, and ethanol at pump (made from Florida sugarcane, of course)?

On global warming...
Eat less meat, slow global warming.
Also, I heard this guy on NPR and the Colbert Report recently. His book Cool It suggests a paradigm shift in thinking about money spent on global warming. He mentioned instead of shelling billions to implement the Kyoto Protocol, this money could be spent more wisely. He mentioned funding renewable energy sources or even investing in the 3rd world as better alternatives that would have a more profound, positive effect on the world in general as well as global warming. He states that global warming is a serious issue, just not an imminent, catastrophic one, as many might suggest.
Interesting.
