Solution to the Global Warming Problem

[Naemeth]

I have just been thinking of various ways we could reduce the impact of global warming, or even reverse it. I thought the best way to do this would be to increase the Albedo of the Earth (currently 0.3 ish on average), so Earth becomes more reflective and so becomes colder. Various ways to do this are:

Paint large areas White (White has a higher albedo than any other colour)

Freeze more ocean around the arctic/antarctic (extremely expensive)

Spraying fine particles of H2O into the atmosphere to make white clouds

Another theory could involve building a huge mirror in space (or transport it to space) to reduce the amount of sunlight coming to Earth, and who knows, we could point the light towards Mars, thus warming it up.
