Earth precession resulted in an ice age that ended about?

Answer 1

10,000 years ago APEX

Answer 2

The last ice age ended about 14,000 years ago, but we cannot be certain that this was related to the Earth's precession.

There's some evidence that ice ages are related to cometary impact events and volcanism, either of which can produce "nuclear winter"-like effects when large quantities of dust are blasted high into the atmosphere and reflect a lot of the Sun's light back into space.

For example, there's speculation that a mini-ice age called te "Younger Dryas" about 15,000 years ago occurred when an impact event happened in northern Canada. This is also about the time that many large mammal species became extinct in North America.

There have been several major volcanic eruptions over the past few hundred years which have resulted in a couple of years of substantially cooler temperatures. For example, in 1815 the Indonesian volcano Mount Tambora erupted in a massive eruption, spewing about 150 cubic kilometers of ash into the upper atmosphere. 1815 became the "Year Without A Summer" as the atmospheric ash reflected sunlight back into space, during which cold weather and frost lingered throughout the year, killing crops worldwide and causing the most widespread famine of the 19th Century.

Answer 3

Earth's precession did not directly cause ice ages; instead, variations in the planet's orbit and axial tilt over long periods of time, known as Milankovitch cycles, influence the timing and severity of ice ages. The last ice age, known as the Last Glacial Maximum, ended around 11,700 years ago due to a combination of factors including changes in Earth's orbit and greenhouse gas concentrations.
