Less low cloud cover lets in more heat from the sun—and may lock in centuries of sea level rise

Phys · · 926 words · By Krystal Kasal

The article discusses a new scientific model published in Nature Communications regarding the persistence of sea level rise. It explains how feedback loops involving reduced low cloud cover and sea ice melt allow more solar radiation to reach the ocean, potentially sustaining sea level rise even after emissions are mitigated.
