Ice core data from Greenland reveals something that challenges everything we think we know about climate stability. The evidence shows that during the last ice age, temperatures shifted from full glacial to interglacial conditions not once, but twice, and each transition happened in just three to five years. Not...

What do we even know about the ice sheet of Greenland? Here’s the story about a squadron that got lost over 🇬🇱 in 1942. Some guys wanted to dig it out 50 years later, believing what “science” told them about how deep they’d have to dig, which would be 30-40’. Reality? 268’.

I'm assuming this hasn't happened just twice but many times as ice sheets advance and retreat. Sea levels drop as ice sheets and vast glacial lakes form leading to massive floods shutting down coastal currents. Once the floods end the pent up warming resumes. YD followed floods.

Climate science calls these 3 to 5 year transitions a mystery, but the data simply reveals the reality of cyclic planetary resets. The idea of long term climate stability is a modern myth sold to the public. The managers of the system have always known that Earth operates on violent, short window purges. Modern infrastructure is fragile by design because surface civilization is meant to be rebuilt after every cycle. The protocol for surviving these sudden shifts and managing the aftermath traces directly back to Genesis 6. You can learn more about this thesis in my book:

The genetic data is pointing toward something dramatic: a severe population bottleneck at the end of the last ice age. Between roughly 14,500 and 11,000 years ago, approximately six million cubic miles of glacial ice disappeared from the continents in just three millennia. That ice had accumulated rapidly starting around 26,000 to 30,000 years ago, and its swift buildup remains poorly explained. What followed was equally extreme. The ice didn't just melt gradually. It converted into water and transferred into the oceans through floods of unimaginable scale. The thermal energy required to drive that kind of melting in such a short span is staggering, and the source of that energy is still not well understood. If the ice melted that fast, what forced it? And if floods of that magnitude reshaped entire landscapes, what did they do to the human populations living through it?

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 Younger Dryas represents the kind of climate shock that would fundamentally dismantle modern civilization. Within the last 250,000 years, Earth has cycled through four major glacial-interglacial periods, each one punctuated by extreme variability. The previous interglacial, the Eemian, lasted roughly 12,000 years and experienced multiple sharp temperature spikes and drops, events that reshaped ecosystems and forced human populations to adapt or perish. The Younger Dryas itself stands out as one of the most abrupt and severe climate reversals in the geologic record. If a comparable event occurred today, with the same speed and magnitude, the infrastructure, agriculture, and supply chains that sustain billions of people would collapse. We would quite literally be returned to Stone Age conditions, not because of nuclear war or societal failure, but because the climate system itself can shift with terrifying speed.

Ice core data shows it: 10 to 12°C of warming hit the Earth in just 1 to 3 years—not millennia, not centuries. That’s 20 times the rate of modern warming. So what did our ancestors do to survive such a violent shift? And more importantly… could we do the same?

The last great ice age terminated in a geological instant - trillions of tons of ice melting away within a few thousand years. Randall’s challenge is direct and pointed. Where did the thermal energy come from to drive that transformation at that speed? There is no consensus answer. The mechanisms that trigger the onset of an ice age and those that bring about its termination remain scientifically unresolved - competing theories exist, but no framework has achieved the kind of broad agreement that would qualify as settled science. That gap matters enormously to Randall because of what is claimed in its absence. If the scientific community cannot reach consensus on what causes ice ages to begin or end - processes that have reshaped this planet repeatedly within the human timeline - then the assertion that climate science is settled becomes extremely difficult to defend. Randall is not dismissing the study of climate. He is pointing at a fundamental inconsistency - that the most dramatic climate events in Earth's recent geological history remain without agreed explanation, while certainty is simultaneously claimed about the mechanisms driving change today. The thermal energy that ended the last ice age is still unaccounted for. That is not a minor footnote. It is a problem at the center of the entire conversation.

He describes the Younger Dryas as the last gasp of the ice age, a period that defies simple explanations. After thousands of years of gradual warming, the planet plunged back into full glacial conditions in less than a year. That reversal lasted twelve to thirteen hundred years before the climate lurched out of it just as abruptly, if not faster. The speed and magnitude of these shifts challenge conventional thinking about how climate systems operate. He emphasizes that this wasn't a slow drift but a catastrophic snap, both entering and exiting the cold period. The evidence points to mechanisms far more dramatic than the gradual processes typically invoked in mainstream climate science.

Today's warming is not unusual. A new study using Antarctic ice core data reveals the roughly 1.1C warming of the past century is not unusual in Earth's climate history. The research analyzes temperatures preserved in ice cores stretching back hundreds of thousands of years. Looking at the last 20,000 years, the study finds that 16% of all centuries warmed by at least 1.1C. In other words, roughly one out of every six centuries warmed as much, or more, as the past hundred years. Also, the ice core records show temperatures rising about 12C since the last ice age, with the last interglacial period around 125,000 years ago several degrees warmer than today. The modern 1.1C century scale increase falls well within natural variability. There is nothing alarming or unprecedented or even rare occurring with Earth's climate.

The terminal moraines left by Little Ice Age glaciers are preserved across the landscape worldwide, and what they show is unambiguous - those glaciers reached their greatest extent since the end of the great Ice Age approximately 11,000 years ago. The Little Ice Age represented a cold extreme within the Holocene, not a neutral mid-point in a stable climate system. Randall Carlson's argument is geological rather than political. When sea level rise and temperature increase are measured against a baseline drawn from the end of the Little Ice Age, that baseline sits at one of the coldest points of the last 10,000 years. A return from an anomalous cold extreme toward the warmer conditions that characterised most of the Holocene will, by definition, produce an upward curve on any graph. Understanding what that curve actually represents - a recovery from a cold outlier or something genuinely unprecedented - requires placing it within the full context of natural climate variability over deep time. The terminal moraines are part of that context, and they are rarely part of the conversation.

Half of Greenland's ice sheet disappeared during the last interglacial period, around 125,000 years ago. Sea levels rose 20 to 25 feet higher than today, not because of human activity, but because natural climate cycles had pushed the planet into one of its warmest phases in recent geological history. The ice melted so extensively that Greenland split into two separate ice domes with a broad corridor of exposed land running east to west across its midsection. This wasn't a minor fluctuation. This was a dramatic transformation of one of Earth's largest ice masses, and it happened without any industrial influence whatsoever. The evidence forces a question: if natural processes alone can drive changes this extreme, how do we separate natural variability from modern forcing in our current climate models? The geological record is unambiguous. Something else has always been going on here, and understanding that context is essential to making sense of where we are now.

He points to a fact that reshapes how we think about lost civilizations: the coastlines of the Ice Age are now 400 feet underwater. During the Last Glacial Maximum, sea levels were dramatically lower, and the most habitable places on Earth would have been coastal zones with access to marine resources and milder climates. If advanced settlements existed 14,000 years ago, they would have been built where port cities still thrive today, along shorelines that are now deep beneath the ocean. He argues that the future of archaeology lies in marine exploration, not because of speculation, but because that's where the evidence would logically be. The drowned continental shelves hold the key to understanding what was lost when the ice melted and the seas rose.

When continental ice sheets reached their maximum extent during the last glacial period, they locked up roughly 6 million cubic miles of ocean water. That volume had to come from somewhere, and the evidence shows it came directly from the world's oceans. Sea level dropped at least 400 feet, with some estimates placing it closer to 450. That's not a theoretical model, that's what the geomorphology and coastal evidence tell us. Today there's concern about sea level rising a foot or two over the next century. That's worth monitoring. But context matters. At the end of the last ice age, as those ice sheets collapsed and returned their water to the oceans, sea level rose more than 400 feet. That's not speculation, that's what happened. Understanding the scale of natural variability in Earth's climate system isn't about dismissing current concerns. It's about grounding those concerns in the full scope of what this planet is capable of.

Start with a single cubic mile of ice and convert it instantaneously to water. The flood that produces would be enormous by any human standard. Now multiply that by six million - the estimated volume of glacial ice sitting on the continental landmasses of North America and Eurasia at the peak of the last Ice Age. All of it is gone now. The question Randall Carlson forces is deceptively simple: how fast did it go? If that volume of ice melted gradually over 50,000 or 100,000 years, the resulting sea level rise and meltwater discharge would be spread thinly enough across time to look almost imperceptible in any given century. But if the same six million cubic miles of ice melted over three, four, or five thousand years - as the evidence increasingly suggests - the implications are categorically different. The meltwater pulses, the catastrophic floods, the rapid sea level rises recorded in the geological record all point toward a process that was far faster and far more violent than the gradualist model has ever been comfortable acknowledging. The ice did not gently fade. It collapsed. Join Randall in the field in New York State for his Finger Lakes Tour, Aug 30 - Sep 5, 2026:
