Ten to twenty-five thousand years ago, vast regions of Earth were buried under ice. Enough ice to equal today’s Greenland and Antarctica combined… twice over. The mystery is not that the ice melted. The mystery is how it melted so fast. Despite decades of research, there is still no clear answer for what triggered the end of the Ice Age. The energy required is staggering, and the timeline challenges long-held assumptions. | The Randall Carlson

Randall Carlson returns to a conclusion he considers one of the most significant and underappreciated findings in the geological literature - that Earth's climate made the transition from Ice Age conditions to something approaching the modern climate in less than a millennium. The authors of the 1960 paper he is referencing described it as one of the most distinct and well-documented climate fluctuations in all of geological history.The date they assigned to that transition was approximately 11,

At the peak of the last ice age, North America was covered by not one but two separate and massive ice sheets - distinct from the Greenland ice sheet which was an entity unto itself. The Laurentide was the larger of the two - roughly equivalent in size to the ice sheet that currently covers Antarctica. Its center was positioned over Hudson Bay and it extended all the way to the flanks of the Rocky Mountains in western Canada. The second ice sheet - the Cordilleran - stretched from northern Idaho

Sixteen-foot mammoths. Lions the size of horses. The late Ice Age was a world built for giants. So here’s the uncomfortable question: if the megafauna were oversized compared to today… why assume humans weren’t? Surviving that landscape meant facing predators far larger than anything alive now. Either humans were physically different...or intelligence, strategy, and cooperation had to compensate fast. The Ice Age wasn’t gentle. And it may not have been designed for small players. | The Randall C

Scientists calculated the energy needed to melt the ice sheets...and Earth didn’t have enough heat to do it gradually. Even African desert heat falls short. Faced with the numbers, the data was shelved. Then evidence of sudden, catastrophic sea-level rise appeared. | The Randall Carlson

Earth’s climate doesn’t just flip between full ice age and warmth — it pulses. From full glacial periods with 6 million cubic miles of ice and global temps 10°C colder… To interglacial warmth like today… And smaller swings in between, called stadials and interstadials. Think of it as the planet’s climate “breathing” — with big and small inhales of ice and warmth. | The Randall Carlson

Peak discharges from Ice Age floods may not be explained by ice dams alone. A major earthquake —or even a cosmic impact into the ice sheet— could unleash forces equal to a magnitude 8 quake, fracturing ice and triggering catastrophic floods. Some geologists suggest multiple events, but even a single dam holding back 2,000 feet of water stretches plausibility. Resealing and failing again and again only multiplies the problem. | The Randall Carlson
