the light to an ice mass is only going to cause the heat to either be emitted from the shade screens or reflected back into the air where it will simply dissipate somewhere else.
The amount of energy you're dealing with on a planetary scale is absolutely mind bogglingly huge and you would have to shade areas the size of whole countries to be able to effect the energy levels on a planetary scale.
Global Warming is crap. Mankind had little or nothing to do with the natural warming trend. It's a huge planet, and mankind is only tiny specks on the surface of the land masses (less then 1/3 coverage). We didn't start it, we can't stop it, and it's foolish to believe we could have even the tiniest effect in slowing it down.
Another good reason for learning how to grow veggies on Mars.
...the energy is still in the atmosphere, so on a grand scale it won't do much of anything unless you're talking about truly massive areas. In order to do anything about a global warming trend the energy has to be removed from the system, not just redirected.
The worst part about the melting of Arctic ice is that the ground underneath it absorbs more heat than the highly reflective ice that is melting away. Ice reflects most of the solar radiation back into space; dirt much less so. This positive feedback will amplify the effects of extra carbon in the atmosphere.

Another point that the global warming deniers seem to ignore is that fact that, while the planet has gone through warming and cooling trends before, these took place over 100's of thousands of years. What we are seeing today is taking place in a much shorter time span (100 years) so the rate of change is much greater thus giving species less time to adapt.
We only get one kick at the can. It is better to err on the side of caution when the stakes are high.

There have been proven archeological records of people planting and growing vegetable crops 1000 years ago in Greenland, there are also records of vineyards in the north of England from the same time. So clearly the earth has been through a period of warming (and cooling) before.
You need to be careful about "clear and unrefutable evidence". Most of you are probably too young to recall the, Chariot of the Gods book and movie of the '70s. In them, every piece of scientific evidence points, undeniably, to the fact that planet Earth was visited by space beings.

However, I don't think there's any doubt that the earth has previously gone through many periods of cooling and warming, there's evidence everywhere showing that....
