The new study published yesterday in the journal Nature concluded that the global oceans may be absorbing up to 60 percent more heat since the 1990s than older estimates had found. Previous estimates from the U.N. Intergovernmental Panel on Climate Change found that the oceans were taking up around 8 zetajoules of energy each year. That’s an “8” followed by a whopping 21 zeros. The new research, though, put it at around 13 zetajoules. For comparison, total energy consumption around the world is around half a zetajoule annually, according to the International Energy Agency.
