Why One Side of Earth Is Rapidly Getting Colder Than the Other
A new study by University of Oslo researchers reveals that the Pacific‑side of Earth’s mantle has cooled about 50 K more than the African‑side over the past 400 million years. By modeling continental positions and seafloor ages, the team showed that the vast Pacific Ocean acts as a thermal conduit, accelerating heat loss through the oceanic lithosphere. In contrast, the land‑heavy African hemisphere functions like a thermos, retaining more internal heat. The findings double the temporal scope of previous work, which only reached back 230 million years.
