Abstract

Earth's energy imbalance is caused by increasing greenhouse gases in the atmosphere and its partitioning between atmospheric, ocean, cryosphere and land heat reservoirs govern the rate at which the global climate evolves.  Most of the imbalance, over 90%, goes into the ocean and accordingly ocean heat content (OHC) provides a primary indicator of climate change, along with sea level rise.  On land and in the atmosphere, major changes occur in extremes of the water cycle and storms with prospects for more intense droughts, heat waves and wildfires, as well as heavy rains and flooding. By adopting a holistic approach that includes top-of-atmosphere (TOA) radiation, vertically-integrated atmospheric energy transports, surface fluxes, and ocean transports, closure of the energy and water cycles on regional scales can be achieved.  However, addressing the major challenges would provide a way to advance the science and prediction of climate.
