There is a lot of talk about global warming.  Well 10,000 years ago there was an ice age, today there is not.  I do not think we had anything to do with either condition.  But I have to agree the globe is warmer.  There is evidence that it has been warming ever since the ice age.  Is this good or bad, who knows it's the environment, and we are foolish if we think we can stop the most destructive force in existence.  But if you believe that "Global Warming is some kind of dragon that will swallow the earth unless some super hero uses some incredible power and makes the boogie man go away" There is a solution to global warming that won't upset every ones lifestyle, will only cost a few billion, can be implement over time, and will allow future generations to manager the global thermometer.  A few points to remember

1.  All of the energy for global warming comes from the sun

2.  The only thing man has been accused of is, letting too much of it stay on earth.

 That's it

the solution is to build a large shade in space.

The shade would need to be in a solar orbit

It would have to be in an orbit that was fixed between the earth and the sun.

It would need to be basically transparent

Something light like nylons stretched between a large wire frame. 

to build your shade

1.  find and orbit that a reasonable size shade  would reduce solar energy reaching the earth

2.  Build a large wire, or plastic frame in that orbit

3.  stretch shade material between the calculated frame members that would cause the required reduction in solar energy

Benefits. 

this project would expand space exploration techniques

It would create a method of manager the earths temperature

Space industrial techniques would be developed that could eliminate the shortage of natural resources on the planet
