Skeptical Science: "Global Warming Has Accelerated"

Skeptical Science (3-25-13) reports:

A new study of ocean warming has just been published in Geophysical Research Letters by Balmaseda, Trenberth, and Källén (2013).  There are several important conclusions which can be drawn from this paper.
  • 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.
  • 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.
