Sunlight drives the Earth’s weather, climate, chemistry, and bio-Recent efforts to improve solar heating codes in climatefocused on more accurate treatment of the absorptionor fractional clouds. A mostly forgotten assumption inmodels is that of a flat Earth atmosphere. Spherical at-intercept 2.5 WÀm−2 more sunlight and heat the cli-by an additional 1.5 WÀm−2 globally. Such a systematicbeing comparable to the radiative forcing change from pre-to present, is likely to produce a discernible climatethat would alter a model’s skill in simulating current cliRegional heating errors, particularly at high latitudes, aretimes larger. Unlike flat atmospheres, constituents in aatmosphere, such as clouds and aerosols, alter the totalof energy received by the Earth. To calculate the netof aerosols in a spherical framework, one must countincreases in both incident and reflected sunlight, thus reduc-the aerosol effect by 10 to 14% relative to using just thein reflected. Simple fixes to the current flat Earth climatecan correct much of this oversight, although some incon-will remain.
