The advantage of the ocean heat content changes for detecting climate changes is that there is less noise than in the surface temperature record due to the weather that affects the atmospheric measurements, but that has much less impact below the ocean mixed layer.

The key points of the paper are that: i) model simulations with 20th century forcings are able to match the surface air temperature record, ii) they also match the measured changes of ocean heat content over the last decade, iii) the implied planetary imbalance (the amount of excess energy the Earth is currently absorbing) which is roughly equal to the ocean heat uptake, is significant and growing, and iv) this implies both that there is significant heating «in the pipeline», and that there is an important lag in the climate's full response to changes in the forcing.

Several researchers have pointed to various other indicators as evidence of «global warming», e.g., Arctic sea ice records, ocean heat content measurements, or animal and plant migration patterns.However, all of these indicators are either too short to compare recent temperatures to temperatures before the 1950s, or else are affected by non-climatic biases.
