As far as I know, only by switching biome or moving up or down, the temperature gets lower as your height above sea level increases.
From the Wiki:
"Biomes have a temperature value that determines if it snows, rains, or does not have either. The required values are less than 0.15 for snow, 0.15 - 0.95 for rain, or at least 1 for neither. These values can be used to determine the heights that snow generates in different biomes. The temperature also drops 0.001(6) (1⁄600) per meter above the default sea level (Y=64), but does not change below sea level."
There is no temperature concept in MC. There is light level and biome specific rules.
Read the bit I quoted from the Wiki!
Each biome has a base temperature and the temperature drops with altitude.
The temperature is used to determine whether it rains or snows and some other things like whether snow golems melt and whether they leave snow trails.
The forest biome has a base temperature of 0.7 and percipitation switches from rain to snow around Y=400 while plains biomes, with a base temperature of 0.8 switch around Y=460.
Picture taken at Y=450 with a forest biome on the left and plains on the right.
The closest snow flakes are drifting to the right and fade out, from right to left, when they hit the border.
I assume this is true only in the Overworld. Or am I wrong?
I don't know, since it doesn't rain or snow in the other dimensions I don't know how to test it.
The Wiki gives the temperature in the End as 0.5 which is low enough for snow golems at any level.
No temperature is given for the Nether but it's listed as a dry biome so snow golems wouldn't survive without fire resistance whatever the temperature.
There seem to be several mods that add temperature and climate related things, at least for 1.12
Well exactly, biome specific rules. As in, biome X snow starts at altitude Y. You can put in a lava lake and it will still snow there. You can build a house out of ice in a desert and it will be perfectly fine as long as you don't put in any light sources over 11.
Nether which supposedly is hot enough to evaporate water instantly, has zero effect on ice.
Is there a way in Minecraft to change the surrounding temperature?
I tried randomly placing lava and ice blocks, but I didn't see any obvious effect to the temperature.

Light sources do melt snow but only very close to them.
Just testing.
Thanks for the reply, Hexalobular.

Indeed, but I wasn't able to know if they do that by changing the temperature, or if this is only related to the light level.

The Wiki claims it's entirely light dependent, melting at light level 12 or above.
Just testing.
