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.
The general argument however is being discussed by rasmus in the context of planetary energy balance: the impact of additional CO2 is to reduce the outgoing longwave radiation term and force the system to accumulate excess energy; the imbalance is currently on the order of 1.45 * (10 ^ 22) Joules / year over the globe, and the temperature must rise allowing the outgoing radiation term to increase until it once again matches the absorbed incoming stellar flux.
