Before the so-called ‘climate warming hiatus’, the answer to this question seemed certain. But our inability to explain observed changes in surface temperature over the past two decades, and associated sea level rise, ocean heat uptake, and the changes to the planetary energy balance in a physically consistent and connected way has caste doubt on our understanding behind this basic question. In this talk, recent and convincing evidence for where the heat is really going into Earth will be presented, and new insights on understanding the planetary energy balance will be described. A number of surprising features of this heat balance, not reproduced in current Earth system models, will also be highlighted and the significance of these features to the basic question posed will be discussed.
