A climate overshoot that creates warmer oceans with lower oxygen levels will reduce the suitable habitat for many marine species long after CO₂ levels have peaked and declined.
We haven’t reached 2° yet, but we’re past the point where it’s even theoretically possible to avoid.
Even if we stopped absolutely all CO2 production right now. What we’ve already released is enough to put us over 2° in the coming years.

Even without any fossil fuels, the current food system alone is responsible for +2°C
