Angular momentum is always conserved in a closed system. This is basic physics. The Earth-moon system is no exception.

Due to tidal friction, the Earth is slowly trading away its rotational speed for the moon’s increasing orbital distance. Eventually the Earth will become tidally locked with the moon. A day will be the same length as the moon’s orbit, with the same side of the Earth always facing the moon. A solar day then last be a month or longer, and the moon will always be in the same position in the sky.

The Earth taken as a unit is not in any way a closed system!

And the “idiots” are worried about global warming?
