I was watching the History Channel and they were showing the time before one of the Ice Ages where the Earth was much warmer than it is now.
They talked about how mankind FLOURISHED in that environment like never before. Plenty of food, no freezing weather, etc, etc
Matter of fact, all mammals flourished.
Then a huge Volcanic eruption happened and (according to scientists), mankind almost went extinct. It sent the Earth into a basic super freeze overnight that lasted for 6 years. The total population of humans was down to 20,000 people.
Scientists think that only the smartest survived and that was the era that our brain capacity as a species rose.
Anyway, the Earth warms and cools constantly throughout time.
And yes...sometimes it's very abrupt.
If the Earth warms as slowly as it is right now...I think it would be a GOOD thing.
One way or another the Earth's climate was NEVER going to remain stable. It's always changing.
The worst possible scenario would be another Ice Age.
