Antarctica is the only continent where the sun can appear green at sunset.

The claim that Antarctica is the only continent where you can see a green sun at sunset is primarily associated with a phenomenon called "green flash." This optical phenomenon can occur anywhere in the world where the horizon is unobstructed, typically observed over oceans or flat plains during clear sunsets or sunrises. The evidence indicates that while Antarctica might have unique conditions for optical effects, the green flash is not exclusive to the continent. Sources like Wikipedia and Smithsonian Magazine mention green flashes and other optical phenomena but do not restrict them to Antarctica, contradicting the exclusivity aspect of the claim.
