   Indonesia, Malaysia, and the islands between them formed a single continuous land mass called Sunderland. In total, something like 10 million square miles of terrain, an area roughly the size of Europe and China combined, sat above water and could have been home to anyone willing to live there. Then over several thousand years, the ice began to retreat. Temperatures climbed, melt water poured into the oceans, coastlines crept in land, and somewhere around 12,800 years ago, the warming stopped abruptly. In Greenland ice cores, the temperature record shows a drop of as much as 15° C within decad…

   And when the ice sheets melted and sea levels rose, a process that was neither gradual nor uniform, but punctuated by dramatic flood pulses, as ice dams failed and glacial lakes discharged catastrophically, the coastal civilization would have been progressively inundated. its physical remains swallowed by water that is now too deep in most places for conventional archaeological survey. We have explored by most estimates less than 20% of the ocean floor in any meaningful detail. What lies beneath the rest is for now beyond our reach. This is where the argument becomes genuinely difficult to res…

   Now, [clears throat] somewhere around there, the climate started warming from the late glacial maximum. Sea levels started coming up, say around 14 12 to 15,000 years ago. Slowly they started coming up but at about 146 there was a massive pulse of meltwater to the ocean. What was driving that? I don't know for sure. But then uh come 12,000 just around 12 a little bit less than 12,900 years ago is the lower younger dus boundary. And this is where the controversy is surrounding uh what happened there. It was a very sharp and sudden return to full glacial cold after several thousand years of grad…

   With the publication of the Firestone at al paper in 2007, evidence for an extraterrestrial impact 12,900 years ago that contributed to the megaponal extinctions and the younger dest cooling. We have made a major advance I believe towards some kind of resolution of the ice age conundrum. But we aren't there yet. uh the five authors of this new paper go on to elaborate upon the paradox right look at the name here rapid delaciation of eastern Maine okay what they're doing here is they're saying here uh the paradox is that well they're about to define the paradox okay um so it begins with conflic…

   Lakes that had been ice free for centuries freeze solid. Plants that had colonized newly exposed ground die off, replaced by hardy tundra species that can survive the renewed cold. The animals follow. Species that had been thriving in the warming world find themselves struggling again, pushed back into smaller refuges, competing for dwindling resources. This wasn't supposed to happen. Earth's climate had been on a steady warming trend for over 5,000 years. All the evidence suggested the ice age was ending. But something had broken Earth's thermostat and now the planet was plunging back toward …

   The gap between what mainstream archaeology expects to find underwater and what Hancock believes is there remains one of the deepest divides in the entire debate. Yet, the submerged world is not entirely silent. In recent years, improved sonar mapping and remotely operated vehicles have begun to reveal traces of human activity on the seabed in scattered locations. submerged stone structures off the coast of Japan at Yonauni drowned freshwater wells near the coast of Israel. Ancient landscapes preserved beneath the Black Sea. None of these discoveries has been confirmed as evidence of an advanc…

   If that is the case, then the oldest layers of one of humanity's first recognized civilizations may lie underwater, inaccessible to conventional excavation. The possibility is not fringe speculation. It has been discussed in mainstream geological and archaeological literature, though it remains difficult to test because underwater archaeology in the Gulf is limited by political, logistical, and financial constraints. Graham Hancock sees these submerged landscapes as the key to a question that has shadowed his work for decades. If an advanced civilization existed during the Ice Age, he argues i…

   Farhat and his colleagues have published on this they talked about that evidence from their point of view for this as well they've never put a date on it but I believe the date is what end of the last ice age 9700 BC everything is pointing to that all the evidence so what we have is that civilization was essentially wiped out knocked down to its knees to use that metaphor whatever metaphor you like really thrown back to a Dark Age something that Katie and I now call Siddha sida which stands for solar induced Dark Age serve ironic isn't it that the Sun which brings light is going to throw us ba…

   So anyways, this was a study going back to 1989 where they were first realizing that the term they use as monotonic. The rise of sea level wasn't a smooth curve. There was at least two pulses what they say uh two intervals of rapid rise which have come to be called meltwater pulse 1A and meltwater pulse 1b. Right? So uh at this point they don't have the detailed uh uh dating of this. Um so let's see changes in continental goes on changes in continental ice volume during the last deglaciation generally have been for inferred from two direct sources geological mapping of the retreating ice margi…

    Even shorter climate fluctuations typically take centuries to develop. But the younger dus developed in decades and ended in years. Something had triggered a rapid catastrophic change in the way Earth's climate system operates. Some kind of threshold had been crossed, flipping the system from one state to another almost instantaneously on geological time scales. Scientists first identified the young in the 1930s, but for decades it remained a geological curiosity, a strange blip in the climate record that nobody could quite explain. Early theories suggested it might be related to changes in so…
