By that I mean are there any natural phenomena that use a low entropy energy source to move heat against a temperature gradient. I know that there are a lot of things that can be interpreted as heat engines, like hurricanes, but I wanted to know if the opposite also happens in nature.
[Question] Are there any naturally occurring heat pumps?
