WebSep 6, 2024 · The Sun powers life on Earth; it helps keep the planet warm enough for us to survive. It also influences Earth’s climate: We know subtle changes in Earth’s orbit around the Sun are responsible for the comings and goings of the past ice ages. But the warming we’ve seen over the last few decades is too rapid to be linked to changes in Earth ... WebA 100% albedo (highest albedo possible) would be all the solar radiation being reflected away. A 0% albedo would mean none of the solar radiation is reflection and thus all is absorbed into or transmitted through the substance. First we will examine sun angle.
