Answer 1

It would look very wet!

Answer 2

If we have non-fossil power sources to electrolyze the water, then very small.  But we don't have such power sources.

Using current power systems to electrolyze the water would roughly triple our present carbon footprint.

Of course... now that I think about it, CO2 doesn't have a foot, so it can't really leave a footprint.
