Scientists believe it was a combination of:
1.Milankovitch Cycles - Changes in Earth's orbit and tilt.
2.Lower CO₂ levels in the atmosphere.
3.Continental positions - Affecting ocean currents
4.Feedback loops - Ice reflects sunlight, causing more cooling
Around 11,700 years ago:
Earth's orbit shifted, increasing sunlight in the Northern Hemisphere
Ice sheets began melting rapidly
Sea levels rose dramatically
Climate became warmer and more stable
This marked the beginning of our current period: the Holocene Epoch
The Ice Age shaped the modern world:
Great Lakes - Formed by melting glaciers
Fertile soil - Glacial deposits created rich farmland
Islands - Rising seas created islands like Britain and Japan
Human civilization - Stable climate allowed agriculture to develop ~10,000 years ago.
