I dont doubt the world is warming - you can see that glaciers have grown smaller.
But it seems there is only 1 solution being brought to the table, that of reducing green house gasses. Why is this the only solution offered? I find it hard to believe that with the technology that we have to day, that if the problem is a reduced ozone layer (caused by increased green house gass emissions) then how is it that there have been no attempts made to repair the ozone.
Can it really be that difficult compared to other things humanity has accomplished?

Actually the hole in the ozone and the planet warming because of greenhouse gases is two different problems.
The hole in the ozone was created because of chemicals like CFC's being put in the air. It isn't the main cause the planet is warming (though I think it does contribute some). The biggest concern about the hole in the ozone is that it lets in increased levels of radiation. Which is bad to most organic life. Sun burns, skin cancer, other cancers, all sorts of fun maladies would be caused by UV and other cosmic radiation.
Greenhouses gases, are gasses like carbon which trap heat in after it hits the earth. Something like 95% of the suns energy bounces back off the earth and into space, however with increased levels of these gasses, the heat and energy stay locked in, sorta like a 'greenhouse'.
