The fact that Co2 is not the main driver of climate coming out of an ice age confounds people to this day... even though it is well established that Co2 is not the main driver of coming out of or going into ice ages, as that is regulated by the Milankovitch cycles.
As far as how coming out of an ice age works, (@ 22) a wide variety of linked processes (starting with the Milankovitch - cycle net insolation effect) are involved; so a little warming leads to a little greenhouse gas release, leading to a little more warming, leading to more releases — one interesting recent study, for example, indicates that melting of the Southern Ocean ice caused a large CO2 release from the ocean along this trajectory:
Re The Holocene, surely it's a time where global temperatures show no sign, until now, of (excluding the rise out of the ice age before that's the cry) temperatures rising.

I'd like to know how the hell the Earth was able to come out of the ice age without humans producing harmful gases that collect in our atmostphere and supposedly trap heat.
Small changes in insolation driven by changes in the Earth's orbit can push the planet into or out of an ice age through the planet's «climate feedback» mechanisms.

A simple rule can accurately predict when Earth's climate warms out of an ice age, according to new research led by UCL.
The ability to discover ancient ice is critical, the researchers say, because it will allow them to reconstruct the climate much farther back into Earth's history and potentially understand the mechanisms that have triggered the planet to shift into and out of ice ages.
Earth is thought to have shifted in and out of ice ages every 100,000 years or so during the past 800,000 years, but there is evidence that such a shift took place every 40,000 years prior to that time.
