Do you mean this question?

There's quite a bit of information missing from the video such as type of camera, weather conditions, location, etc. What type of explanation could you possibly expect from anyone absent information such as this?

Type of camera and weather conditions are self-evident and immaterial, and the location information is there in the video description.

Light is curving. We can see the inferior mirage on the surface as the drone descends.

Why on a FE does the horizon get further away as the drone ascends?
At the start of the video you can clearly see the boat is pretty much on the horizon when the drone is low but as it ascends the horizon goes further and further past the boat.
On the globe earth we know why, you're looking over a curve and the higher you are the further you see over that curve.
If in your world the horizon is the "merging of perspective lines" why does that happen at a different distance depending on your altitude?
How does perspective "know" your altitude?

Well, if light is bending down from the object, wait, maybe it’s up to shine the bottoms of clouds at sunrise and sunset..  the answer must be the altitude and refraction...  The air near the ground is thicker and higher temperature causing refraction, as you go higher, there is less refraction so you can see farther?

Tom is right. Inferior mirage is evidence that light is "curving."

But he is wrong if he is implying that that explains other visual/optical phenomena in that video? What does inferior mirage mean? How does it form? How does it fit into the explanation of what else we see in that video? The mere presence of an inferior mirage at certain viewing angles doesn't resolve or explain or relate to other visual phenomena seen in that clip.

Atmospheric refraction is greater over "cold" water and air near the surface is colder than the water. In these conditions you can see 'farther' than you normally can over warmer less dens atmospheric conditions.
