Much has been made for the last few decades of the "Greenhouse Effect" and the "Enhanced Greenhouse Effect". So, let's review:
Let's start from basic principles; let's follow "A Day in the Life of a Global Warming (NOT) Photon".
1. A Photon of Visible Light (a.k.a. Sunlight) arrives on the surface of the Earth. Nothing spectacular here, happens all the time.
2. This Photon is either reflected or absorbed by the surface of the Earth. The visible reflected portion is not of much interest to the Man-made Global Warming Hypothesis, so we will ignore it for now.
3. The absorbed Photon raises the temperature of the Earth by a small amount, no dispute here.
