It's never too late, that's not what "the science" says it's what the clickbait vulture news bullshit you're reading is saying. The real science on the matter is that every day things get just a little bit worse, and every improvement makes things just a little bit better. There's no magic cliff, no point of no return, just one day after another.

There are tipping points, when warming accelerates and becomes irreversible.

There’s some debate in “the science” about how quickly we’ll reach that point. Limiting warming to +2°C was not a scientific position; it was political, based on what people thought was achievable. Before the Paris Agreement, 2° was not considered “safe”.

Anyway, it turns out we’re going to zoom past 2° in the next couple of decades.
