I want to know the answer to the following question:
What percentage of the Earth's heat is derived from the Sun's infrared light?
All the background I'm provided with is that "Objects at room temperature will emit radiation concentrated mostly in the 8 to 25 µm band, but this is not distinct from the emission of visible light by incandescent objects and ultraviolet by even hotter objects (see black body and Wien's displacement law).". Is that enough to answer the question?
Answer: no
