Couldn't we, basically build a mega structure to block out the sun, and put us in a near ice-age to build up ice stores? We maybe have 5 years of horrible wint

Couldn't we, basically build a mega structure to block out the sun, and put us in a near ice-age to build up ice stores? We maybe have 5 years of horrible winters and ice, but then after we have enough ice we can leave the shade down for a bit.

we destroyed whole ecosystems by introducing foreign wildlife. Both accidentally and intentionally. I am not too optimistic with 'solving' the climate change via one simple solution. I'd rather see UN drop one giant ice-cube onec in a while into the ocean.

we don't even spend money to maintain our infrastructure, and we're running a massive deficit, and the current leadership in the US has been removing regulation connected to environmental protection. How the hell are we going to get the largest governments of the world or this country to build a mega structure to block out the sun?

  To make a .1mm (1/32") aluminium foil that shadows all the Earth, the cost is approximately 84 trillion dollars https://www.wolframalpha.com/input/?i=pi+*+%28%28earth+radius%29%5E2%29+*+0.1mm+*+%28density+aluminium%29+*+%28price+aluminium%29+in+dollars https://www.wolframalpha.com/input/?i=pi+*+%28%28earth+radiu... and that does not include the material to provide some structural support for the thin surface. And it doesn't include shipping and handling that is at least 10000 more if you put it at a geostationary orbit [1]. (And later remember to consider some maintenance cost, fuel for orbit adjustment...) If you want to cover only a 1% of the surface, just divide that by 100, that is about 8400 trillions dollars. [1] It's a big structure, so the calculation is more complicated than the calculation with a small satellite. Ask a rocket scientific before launching.
