To me, it is more likely the fluctuation in E-UV coming from the sun that causes the warming and cooling effects by changing the reactions that are happening on TOA, i.e. O3, HxOx and NOx are rising now, causing more back radiation of F - UV, meaning less energy going in the oceans.

You do not have the direct heat from the Sun which is the Sun's thermal energy in transfer by radiation.

The Earth receives energy from the Sun in the form of visible light and ultraviolet radiation, which is then re-radiated away from the surface as thermal radiation in infrared wavelengths.

Although only 1 percent of the sun's energy is emitted at ultraviolet wavelengths between 200 and 300 nanometers, the decrease in this radiation from 1 July 1981 to 30 June 1985 accounted for 19 percent of the decrease in the total irradiance over the same period.»

The microwave energy (within the IR REGION) will not produce «sun burn» (a mild radiation burn from UV - A and UV - B) but would produce too much intrinsic heat in outer cellular structures, stopping internal cellular processes and most likely the formation of «life as we know it».
