Longer days (keeping the Earth spherical)

New studies say climate change makes the Earth less spherical and therefore spin slower, making our days a little longer. This is due to the ice caps melting and gravity and centrifugal force redistributing the body of water on the planet towards the equator.

Not only are we reshaping the surface of the Earth, we are actually changing the shape of the planet. Policy decisions in this case can be directly linked to changing the shape of the planet.
