In fact it turns out that as some parts of the Earth are getting warmer, other parts are losing heat. The surprise in the new study is how unevenly the heat is dissipating, but the reason makes intuitive sense: Parts of Earth have been insulated by more landmass, creating something of a Thermos layer that traps heat. For their study, the Oslo scientists divided the Earth into an African hemisphere (mostly land) and a Pacific hemisphere (mostly water). The seafloor is far thinner than the bulky landmass, and temperature from within Earth is “quenched” by the enormous volume of cold water that’s above it. The research shows that the Pacific hemisphere has cooled around 50 Kelvin more than the African hemisphere.
