It's the speed that's the problem. Most warming periods, at least since life has been around, were so gradual they are imperceptible in a human lifetime. Even in a civilisation lifetime.
The last increase took about 20,000 years to rise 6c. We've done that 1c in about 100 years. It's dramatically faster.
