Atmospheric refraction, due to the different temperature/altitude profile in the atmosphere at different times of day...makes distant mountains appear taller or shorter.
The attached photo is a comparison of what I shot yesterday afternoon and this morning. The camera was set up within inches of the same location for both shots, and those mountains are between 50 and 120 miles away...so I'm saying that any parallax effect from camera location is essentially zero.
I have annotated with arrows where it's easy to make a comparison of how the near and far ridge lines overlap differently in the two photos.

Imagine the care that was needed to conduct surveys before the GPS/GNSS era:

"The Great Theodolite built by Troughton & Simms in London stood nearly 1.5m high, had a horizontal circle one meter in diameter, and could read angles to a single second of arc. Moving it required 30 porters and sometimes elephants."
"The reduction of Nicolson’s observations was a colossal task. Each ray from each station had to be corrected for instrumental error, for temperature and pressure, and for the curvature of the Earth. Above all, they needed to correct for atmospheric refraction, which at those distances could amount to six or seven minutes of arc and change from hour to hour."

There is currently a halo (22° halo, https://en.wikipedia.org/wiki/22%C2%B0_halo) around the moon.
The ring is created by moonlight refracted by hexagonal, non-oriented ice crystals. These ice prisms are found in high-altitude clouds (cirrus clouds). This type of halo is quite common. Its radius is 22°, which is about 44 full moon diameters.

More #refraction in the hallway at 10:30 in the morning when me and my youngest were about to leave the house for a scouts event. We loved the tiny #rainbow #dispersion
A lovely ray of light in the halway. #refraction #dispersion
Our moon, winner: The Trace of Refraction by Marcella Giulia Pace
This image from Sicily in Italy captures the phenomenon of atmospheric #refraction, where moonlight passes through dense layers of Earth’s atmosphere near the horizon, bending in a manner similar to light rays through a prism.
