6 Top of atmosphere (TOA) Net Short Wave (W/m2)

7 Top of atmosphere (TOA) Net Long wave (W/m2)Net total (W/m2)

8 At the surface Net short wave (W/m2)Net Long wave (W/m2) Net total (W/m2)

9 Sensible heat flux (W/m2)Latent heat flux (W/m2)

10 Global warming GHG concentrations in the atmosphere trap the long wave outgoing radiation of the surface There is a fast feedback of a warming atmosphere on its water vapor content Feedback of the surface albedo, e.g. sea ice, deforestation, … Aerosol concentrations lead to scattering and absorption of incoming radiation and affects the cloud building process Natural changes, e.g., solar activity, volcanos, orbital parameters
