It was that ocean heat that caused the First Pulse to pulse, and later brought on the second one. People sometimes say no one saw it coming, but no, wrong: they did. Paleoclimatologists looked at the modern situation and saw CO2 levels screaming up from 280 to 450 parts per million in less than three hundred years, faster than had ever happened in the Earth's entire previous five billion years {can we say "Anthropocene," class?}, and they searched the geological record for the best analogs to this unprecedented event, and they said, Whoa. They said, Holy shit. People! they said. Sea level rise! During the Eemian period, they said, which we've been looking at, the world saw a temperature rise only half as big as the one we've just created, and rapid dramatic sea level rise followed immediately. They put it in bumper sticker terms: massive sea level rise sure to follow our unprecedented release of CO2! They published their papers, and shouted and waved their arms, and a few canny and deeply thoughtful sci-fi writers wrote up lurid accounts of such an eventuality, and the rest of civilization went on torching the planet like a Burning Man pyromasterpiece. Really. That's how much those knuckleheads cared about their grandchildren, and that's how much they believed their scientists, even though every time they felt a slight cold coming on they ran to the nearest scientist {i.e. doctor} to seek aid.
