Re footnote 2: Good effort, but it's not reflection (albedo). Greenhouse gases are all about the part of solar radiation that isn't immediately reflected.
Most incident sunlight is absorbed (either in the lower atmosphere or on the surface). At the same time long wave infrared radiation (heat) is emitted, proportional to the temperature of the surfaces. Greenhouse gases in the atmosphere slow down the rate at which that heat escapes to space.
- joebiden2 4y agoThis is one definition of albedo¹, a more sophisticated one is here² ¹ https://en.wikipedia.org/wiki/Albedo https://en.wikipedia.org/wiki/Albedo ² https://www.pnas.org/doi/10.1073/pnas.1918770116 https://www.pnas.org/doi/10.1073/pnas.1918770116 Please think about the effects to understand albedo. It can be perceived as a complex topic, but in reality, it isn't. Good night
