"The planet may be more sensitive to warming that previously thought, making climate goals more difficult to meet...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. ADVERTISEMENT 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. This suggests that the Earth, as a whole, is more sensitive to climate change than previous estimates would imply. And that means the planet may respond more strongly to future greenhouse gas emissions than expected..."
