Please note
shortwave albedo of Earth has large spatio - temporal variations, but its annual global average is restricted to a narrow range, even if it is not determined by simple material constraints, but by an intricate interplay between many internal degrees of freedom.

Most
of it temperature related which was driven by change in
albedo due to
Earth dynamics — some 25W / m2 less reflected
shortwave.
Most radiative change happens in the
shortwave — roughly an
albedo of 0.25 in a blue green planet to 0.50 in a snowball
earth.
