Why is the Earth speeding up?

The speed at which the Earth spins is affected by all of its distinct parts, including its inner and outer layers, tides, ocean levels, and climate. One hypothesis for the recent acceleration stems from the fact that some of these parts are changing rapidly due to the climate crisis.
