One possible explanation is I am not a climate scientist, so I may look at the physics of the atmosphere with more emphasis on the physics. The whole idea of greenhouse-gas warming is based on the "observation" that planets with atmospheres are 33 degrees C warmer than planets without atmospheres. Now, planets satisfying these criteria are not exactly jumping out of the sky. This would mean to me that this atmospheric-effect theory never actually has been experimentally tested according to the scientific method. This may be acceptable to 97 percent of climate scientists, but it tends to make me itch. Let's say, however, that there is something to it. Having established that our atmosphere warms the planet by 33 degrees C (notice, I didn't say how), what gases are the major components of today's atmosphere? There is nitrogen (78 percent by volume), oxygen (21 percent), water vapor (about 0.2 percent; it varies), and carbon dioxide (0.04 percent by volume). Other gases are at much lower concentrations and will not be considered.https://climatechangedispatch.com/wp-content/uploads/images_pics7_earth_2.jpg
