| Zusammenfassung |
| Motivated by an apparent inconsistency between top of atmosphere radiative fluxes and ocean
heat content changes, we present a re-analysed assessment of changes in radiative heating of
the planet since 2000 and find (i) no evidence for inconsistency between changes in radiative
energy at the top of the atmosphere and ocean heating, (ii) variation in net radiative flux
consistent with El Nino Southern Oscillation and (iii) continued heating of Earth’s climate
after 2000 of magnitude 0.5±0.43Â Wm-2, slightly lower than previous estimates but
nevertheless significantly positive. Changes in net radiation estimates since 1985, using a
variety of satellite products, are compared with CMIP5 climate model simulations. Models
experiments which prescribe realistic sea surface temperatures (AMIP5) are able to
capture the interannual variations well. Changes in net radiative cooling of the
atmosphere is also analysed and links with the hydrological cycle will be discussed. |
