- Completely contrary to the popular contrarian myth, global warming has accelerated, with more overall global warming in the past 15 years than the prior 15 years. This is because about 90% of overall global warming goes into heating the oceans, and the oceans have been warming dramatically.
- As suspected, much of the 'missing heat' Kevin Trenberth previously talked about has been found in the deep oceans. Consistent with the results of Nuccitelli et al. (2012), this study finds that 30% of the ocean warming over the past decade has occurred in the deeper oceans below 700 meters, which they note is unprecedented over at least the past half century.
- Some recent studies have concluded based on the slowed global surface warming over the past decade that the sensitivity of the to the increased is somewhat lower than the IPCC best estimate. Those studies are fundamentally flawed because they do not account for the warming of the deep oceans.
- The slowed surface air warming over the past decade has lulled many people into a false and unwarranted sense of security.
"ORAS4 has been produced by combining, every 10 days, the output of an ocean model forced by atmospheric fluxes and quality controlled ocean observations."
Accelerated Global Warming

"In the last decade, about 30% of the warming has occurred below 700 m, contributing significantly to an acceleration of the warming ."
Some 'Missing Heat' Found
Good News for ? Probably Not
"it contributes to the overall warming of the deep ocean that has to occur for the system to equilibrate. It speeds that process up. It means less short term warming at the surface but at the expense of a greater earlier long-term warming, and faster sea level rise."
