Maybe you need to fix the sun!
Nothing wrong with the sun. We have an ironclad guarantee that it will continue to operate continuously and reliably for the next five billion years. (At the end of which it will spontaneously blow up and destroy Earth, but let's not worry about that right now.)
Now we can't do away with the clouds completely, so if you really like sunshine I would suggest the next best thing ... invest in my new resort area to be constructed in the heart of Antarctica.
After the space mirror is put in place in a polar location, it will reflect sunlight down on most of Antartica. Together with the more haphazard appearance of the regular sun, this area will for half the year enjoy two suns, and it will never be in darkness again.
Soon enough, all that yucky ice will be somewhere else, and we can get on with serious gardening, meteorite prospecting, and other interesting things that couldn't comfortably be done before in Antarctica.
Don't miss out on a golden opportunity!
