It happens over geological ages, far beyond the perception of human life, you don't have periods where it warms so dramatically faster with no time for the ecology to adjust.
Sephiroth graph isn't to scale, there is a reason whoever produced it hasn't put more precise years at the bottom because on a scale of even 100,000 years, that dramatic spike upwards would find it difficult to fit on. This rate of warming didn't start 10,000 years ago - or wherever that uptick meant to start - it started 100 years ago.

No, we wouldn't because it would have taken longer to occur than any of us would have been alive.
The warming event 140,000 years ago was the Eemian period. It took roughly 15,000 - 20,000 years to go from ice age (-4) to around +2c. 6 degrees warming over 15,000 years. That's a rate of 0.0004c increase per year.
Meanwhile, it's taken since 1880 to rise 1c. That's a take of 0.007 increase per year. That's 17x faster.
