ELI5: Wasn't the carbon, now being emitted by fossil fuels, at one point in the atmosphere? How did the earth survive back then. What factors have changed this time around?

The Earth survives plenty of things that have killed almost all life on it. That's the difference. It's not about destroying Earth, but the destruction of life on Earth. One of the big issues with the current warming is the rate at which its occurring, which is not allowing for enough generations of various species to be born with enough genetic variation to develop survivable traits. The amount of climate we've seen over the last 100 years should have taken several hundred to a couple thousand years to occur.
