Comment: There has been an uptick in sinkholes and other land deformations world wide. Not all of them can be attributed to underlying conditions such as limestone erosion. One might wonder if they are perhaps related to the Earth's slowing rotation, which would cause the lithosphere to slip as the rotational speed of Earth's different geological layers become mismatched.
