I am wondering if the man-made carbon emissions put in the Earth's atmosphere over the past 100+ years, and also the relocation of oil around the Earth over this same time period, has had any measurable effect on the rotation of the Earth.
By mankind extracting oil located deep in the ground and from under the ocean floor, the mass of this oil has thus been moved farther away from the center of the Earth. Its mass has also been moved farther away from the center of the Earth by it being put high into the Earth's atmosphere via the injection of carbon emissions into it from oil & gas burning sources such as electrical power plants, cars, airplanes, etc. As far as I know, this has resulted in the Earth now having a heavier atmosphere than it had 100+ years ago.
So, I am wondering if all this oil mass/weight transfer away from the Earth's center may have had a measurable effect on the Earth's rotation, due to the Law of the Conservation of Angular Momentum, perhaps causing a slight slowing or increase in its rotational speed over the past 100+ years.
Moreover, I am also wondering if by slightly changing the mass of each of the Earth's continents, due to the relocation of trillions of tons of oil between the Earth's continents by oil tankers over the past 100+ years, has somehow also had a measurable effect on the Earth's rotation.
Has a heavier atmosphere and the relocation of oil around the Earth had a measurable effect on the rotation of the Earth?
