Given that every other warm interglacial period since the Pliocene ended in a slow slide into another ice age, a steady warming trend is indeed remarkable. There have been some 18 ~100,000 year ice age cycles since the Pliocene, and each glacial maximum ended about 3X as rapidly as it formed, so the world should be slowly cooling at present - but thanks to Homo ignis burning all the fuel, that trend has been reversed.
If you like, you could argue that human industry has saved the planet from another ice age anytime soon, but the job is certainly done at this point so we should stop burning fossil fuels now and try to stabilize the atmosphere at a constant steady state composition.
