Ironically, this could be the time extension humanity needs to wean off itself from fossil fuels before irreversible changes in ocean chemistry start killing ecosystems(such as oxygen producing plankton) and reducing oxygen% in atmosphere.
``Scientists believe that phytoplankton contribute between 50 to 85 percent of the oxygen in Earth’s atmosphere``
Ocean acidification is killing them, reducing our oxygen supply. The deforestation and modern agriculture cuts the rest of oxygen sources.

The minimum oxygen concentration for human breathing is 19.5 percent. At below 17%, your mental abilities become impaired and you'll feel exhausted. It might not necessarily be fatal but for the young, old and weak, they might need special breathing apparatus, if the general public doesn't already need one.
