It is possible. You need a small hole at the top for ventilation. Keep the fire small and in the middle. Otherwise could get carbon monoxide poisoning.
Traditionally, that 'fire' would be an oil lamp fueled by rendered blubber, mostly because it might be hundreds of miles from the nearest tree or other source of readily combustible fuel.
The physics does not check out. If you get this thing to 60°, you get a very wet environment that is not good for keeping warmth. If you melt the inner surface, it would be molten. The "cold outside freezes it" does not make any sense. Also the packed snow is much better insulator than a crust of ice. And it would take quite a large fire to raise the temperature from -50° to 60°. You just don't get that much firewood. But. Getting it from -50° to -20° could be essential for surviving a night.
Judging from the light color it is either a pressurized gas lantern or an incandescent light lantern: if it isn’t a fire. As that warm yellow-orange light color only comes from those sources.
It COULD be an LED lantern, but even the expensive ones are retina-melting white.
See my “or it’s fake” addendum. The only reason someone would carry a color filter into an environment cold enough to sustain building an igloo (it does require a certain environment) to take a picture of an igloo is for a staged (fake) picture.
Or it’s a fake igloo with a fake light source all staged up for marketing purposes.

ice would melt on the inside.... and re-freeze on the outside?... tell you never touched snow without telling you never touched snow.

That's an iglow.

The bigger problem is finding enough wood for a fire.

The lack of smoke and a chimney tells me this is what an igloo looks like when you put a lamp inside it.

I mean it could also come from a colored light. It's not exactly new technology.

You aren’t wrong.

Or it’s fake. Ya know, cuz that option always exists in this day and age.

maybe it is 60⁰ in Fascist units

60° is the angle between inside wall and ground, duh.
