When the atmosphere slows the Earth: Uncovering a subtle signal of climate change
Climate change could be subtly affecting Earth’s rotation as atmospheric circulation patterns shift due to global warming. This phenomenon, where changes in wind patterns redistribute angular momentum between the atmosphere and solid Earth, has been observed but its long-term impacts remain uncertain.

Our results, therefore, position atmospheric changes as an additional, climate-driven component within this broader rotational system.
The atmosphere, oceans, cryosphere and solid Earth are tightly coupled. Changes in one component inevitably propagate into others, sometimes in unexpected ways.

AI analysisThis finding underscores that climate change is not just altering surface-level phenomena like temperature or precipitation but also fundamentally reshaping the Earth's rotational dynamics. This has implications for various geophysical processes and could lead to more accurate modeling of long-term climate impacts.
The Earth's rotation is expected to slow down by about 10-18% of the long-term tidal friction trend by the end of the 21st century due to atmospheric changes driven by global warming.
