Arid exoplanets may lose climate stability even inside habitable zones
New research argues that worlds with too little water may fail to sustain the carbonate-silicate cycle that helps keep Earth temperate, suggesting that some planets inside habitable zones could still drift toward Venus-l
Key Takeaways
- Researchers argue that too little water can disrupt the climate-stabilizing carbon cycle on rocky planets.
- The study says rainfall is critical to silicate weathering, which removes carbon from the atmosphere.
