Rising sea levels caused by climate change are making the Earth "fatter"
at the equator - slowing down its rotation and making the days longer.

Oh swell! So we can measure the rise in sea level by measuring
the length of the day. Data, anyone?
Is that planet earth picture an AI product? With the sun in
the background, we should have been looking at the night side.
Not very I, this AI.

It is pretty much uniformly distributed over the Earth's surface.

It is real - inferred from VLBI data. It is sensitive enough to detect seasonal variations in the northern hemisphere summer (and has been for
quite a while). The asymmetry of land masses north and south of the
equator. When trees are in leaf in US Canada Russia forests the Earth's moment of inertia is increased by the weight of sap and leaves.

Fairly recent example of such data above. This is the current global
solution from the Paris Observatory (seasonally detrended).

Most of the slowdown comes from tidal drag from sun and moon. Some
changes are a result of oceanic currents shifting around too.
Effects of glaciers melting can go either way depending on what altitude
the ice in the glacier was at (many glaciers are at high altitudes).
