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.
Amy ideas how close we are to this actually happening? I saw we hit 1.8° a few weeks ago… .2° is not a big difference…

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

That depends on human decisions.
Phase out fossil fuels and end deforestation over the next few decades and it never happens.
Keep on burning more each year? A few decades.
A few decades it is then 😔
It doesn’t have to be that way. Do what you can to put your thumb on the scale of policy, and we might shift things.
I know, sorry to be so defeatist.
