My grandpa made me realize something

where is everyone getting their oxygen if the trees are dead? well, most of the trees.

There's a LOT of oxygen in the atmosphere. It would take quite a while for it to get depleted enough to make much of a difference, especially with the significant reduction in animal life caused by the extreme cold.

There's also hydrolysis. And CO2 scrubbing to pull some of the oxygen back from burning coal. Luckily, it's so ♥♥♥♥♥♥♥ cold that it snows carbon dioxide, so you have as much as you'll ever need on that part.

Hell if those researchers are any good, they could probably devise a more efficient way that we have. They could turn all that CO2 into O2 and C, AKA more coal!

Don't start poking the plot holes in the physics, you'll be here all day :)

Most oxygen comes from the sea though not the forrests..

[Caynor]

There are less than a million humans left alive. They will have plenty of oxygen for decades.

This, it blew my mind as a kid learning that most of our oxygen comes from things like algae from the sea and not the forests on the land. I'm all for saving those forests too but it was an eye opener to learn about.

Trees don't make oxygen. They consume just as much as they "produce" during the day.

[Jazz Ad]

Given the current population of the Earth, if all oxygen production stopped already we'd have about 6000 years of ample supply.

Ah yes, the sea that froze much like everywhere else in Frostpunk.

Only the surface of it, salt water is far harder to freeze than fresh water and the opening cutscenes of the game do show that light was still able to get down there.

The On the Edge settlement Hotsprings shows that you can still find liquid water in the earth even after the storm so it's a very safe bet the same is true of the oceans.

The life under the ice is going to be trapped under the ice,heavily reducing sun exposure for what ever algae survives. And after the -150c storm great storm, even more mass die off will occur. On top of that in endless, there's even more storms to make sure there will never be a mass revival as the ice would grow thicker after each storm and wouldn't unfreeze because salt hardly make difference at those temperatures of -60c at the average warmest.

My point in that comment was simply that water still exists in liquid form on the planet even after the storm.

While I do agree that after the storm the ice over the ocean would be hell of thick, as far as we are aware only the scenarios are cannon and not anything from the Endless mode. So chances are good there aren't any weekly storms reinforcing the ice.

The sea ice was thick enough to let a crawler roll over it in the intro to A New Home. The oceans are largely dead before The Storm happens. There will be surviving life, but not much.
Similarly, photosynthetic life on the land will either be frozen, shredded by the wind or buried by the snow. The oxygen will run out. Thankfully with the biggest consumers remaining being the dozen or so generators that survived the survivors will have a few years to plant some forests before suffocating. The geologic processes that consume unstable elements in the atmosphere like oxygen and carbon will be greatly diminished by the freeze.

Go in the hot house for 5 minutes to get your oxygen ration.

[Sabaithal]

Funfact: Most of the oxygen supply in the atmosphere is actually supplied by the ocean, specifically plankton, not trees.

And like someone else already stated, it would still take a while to expend all the current amount of O2 in the atmosphere, especially after a near mass-extinction even took place such as the one in frostpunk that wiped out a majority of oxygen breathers.
