Solar geoengineering involves techniques like creating low-altitude marine clouds or increasing the aerosol concentrations in the stratosphere

Much like tailoring different articles of clothing to match the weather, a new study suggests customizing solar geoengineering to compliment the needs of different regions in an effort to combat global warming.
 
Solar geoengineering is a method of fighting global warming by reflecting sunlight back into space. Solar geoengineering involves techniques like creating low-altitude marine clouds or increasing the aerosol concentrations in the stratosphere.
 
A group of researchers from the California Institute of Technology, the Carnegie Institution for Science and the U.S. Department of Energy (DOE) have created a study that shows how tailored solar geoengineering can help certain regions fight global warming as needed rather than a uniform method of solar geoengineering -- which could negatively affect weather in certain areas. 
 
Some are opposed to solar geoengineering because it can affect weather around the world. For instance, greenhouse gases suppress precipitation, and reflecting a certain amount of sunlight back into space would not restore this precipitation. Greenhouse gases and aerosols affect Earth's heat and rain in different areas in different ways. With limited sunlight, everything could change and have dramatic consequences.
 
But that's where tailored solar geoengineering comes in. Different regions would only receive the amount of reflection needed to keep weather stable, yet reduce causes of global warming. The researchers used a model to predict how this would work, and found that reflecting sunlight away from the Earth based on region and season could help fight global warming without seriously affecting weather. 
 
"There has been a lot of loose talk about region-specific climate modification," said the study. "By contrast, our research uses a more systematic approach to understand how geoengineering might be used to limit a specific impact. We found that tailored solar geoengineering might limit Arctic sea ice loss with several times less total solar shading than would be needed in a uniform case." 
 
However, the researchers did add that solar radiation management could produce uncertain outcomes.

I think you missed the fact that his post was dripping with sarcasm.....

yes but the underlying premise is that "government" and "UN" plans are, a priori, doomed to failure.

Was just clarifying that the reasons for failure of UN initiatives are never the failure of "the UN", but rather nearly always stemming from the conflict of interests between nations who then use their leverage within the UN to stymie this or that program.

Kind of like how people blame "Congress" in shorthand, when really the reasons for failure rest on individual members, their agendas and their personalities.

Kind of like Harry Reid, and his Dunning-Kruger brain, and his followers causing such problems in the Senate?

A proper game theory approach wouldn't limit the reasons for failure to one subset but rather look at ALL members within a given entity and see how their interactions play out.

But yes, in that you are specifying actual individuals you are on the right track. However I worry that your analysis may be flawed if you limit yourself to blaming problems on one subset of the larger group, as could be the case with your example.

As always, we need to look holistically at how these individuals act+react, and how their counterparts act+react if we are to come to a better understanding of why policy fails to gain traction.

Accurate point. There is enough blame to throw around to both parties and all the alliances within them. There are plenty of people in both parties who both act on a complete miscomprehension of reality and on their own selfishness.

However, Harry Reid has always struck me as that unwavering, confident, complete idiot that can never admit to himself that he has ever made a mistake. He has that confidence that can only come from a complete inability to comprehend reality. He's a perfect example of the Dunning-Kruger effect in action. I just absolutely hate that guy. There have been those people in the Republican party, too, but, thankfully, they're dead now.

Overall it isn't just the fault of those in government, but those who put them into their position. Voters have just as much blame as those in office and until we all take the responsibility to learn how government works and become involved in the process we will be stuck with the same lot of leaders who only serve their own interests.

There are a few elected officials who truly have the heart to serve their constituents and a few constituents who have the knowledge to make wise decisions when voting, but overall those are the rare exceptions to the rule.

Hehe, yea i was being sarcastic. I could see it happening... and the sparkle in Al Gore's eye.
