Global Warming: Good News, Bad News

This article is rather interesting:  
http://revmodo.com/2012/08/31/reflecting-sunlight-fight-climate-change/   
It describes some technically feasible ways to reflect sunlight away from the earth, so as to reduce global warming.  

Most people are unaware that on average, the past few years have been relatively cool.  According to some experts, the reason is that, in their race to industrialize, the Chinese have been burning so much coal!  The coal is impure and contains sulfur.  When the coal burns, it adds more carbon dioxide (the major greenhouse gas) to the atmosphere, which ultimately will exacerbate the situation.  However, the sulfur in the coal burns, too, and turns into sulfur dioxide. The sulfur dioxide also goes into the atmosphere, but it does a great job of reflecting sunlight.  Thus, in a sense, the technology is already proven.

So the good news is that we can do it; the bad news is that if we can do it, then why stop putting carbon dioxide into the air?  And will a reflective band-aid work as well as hoped?  Check with Murphy's Law...

Root causes of Global Warming, i.e., global climate change

Nearly nobody seems to notice or want to talk about the connection between burgeoning human population, degradation of the environment, exhaustion of natural resources, and reduction in quality of life.  There is a connection -- and a causal relationship.  Meanwhile, good Christians, Catholics, Mormons, Muslims, Hindus, et al, continue to reproduce themselves willy-nilly because their religions and relatives tell them to, so they'll have someone to take care of them when they're old, and to maintain an illusion of immortality.

Of course, most people want and have kids, and only a cad doesn't love children.  That's why the discussion ends before it begins.  "...for whatsoever a man soweth, that shall he also reap." (Galatians 6:7 KJV, Christian Bible)

However, there is a glimmer of hope to be seen.  In time, the population of industrialized countries becomes stable.  (Why?  You tell us.)  The only exception is, as usual, the U.S.A., but in that case it's due to its immigration policy (or lack thereof).  Unfortunately, industrialized countries are enormously wasteful and polluting, and they have an insatiable thirst for oil.  So let's look for a country whose energy needs are satisfied by a non-carbon energy source.  When and where will it happen?  Will its population stabilize?
