Missing heat found in oceans, global warming has accelerated in past 15 years
The folks at Skeptical Science eat climate science for breakfast and really know their stuff. They have published a very interesting overview of a recent climate study by Balmaseda, Trenberth, and Källén (2013) that shows that warming hasn't slowed - in fact it's the opposite - and heat that was previously thought to be missin can be found in deep oceans. Here are the main points:
- 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 climate to the increased greenhouse effect 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.
