‘But Gabriel got his big refrigerator?’
‘Pretty much. He built huge pumps that lifted sea water to the centre of the continent, to the top of the old ice dome, and froze it all out, metre by metre. It took five centuries for the drawdown to be complete – the sea-level drop was contained at about a centimetre per year, and the carbon dioxide drawdown at about a gigatonne per year. So the power required was relatively trivial, year by year, a fraction of the planet’s annual output in the Anthropocene days. Now the programme has settled down to long-term stabilisation; you need less refrigerating power because so much of the sunlight is deflected by the ice itself. The power generation nowadays comes from a GUT facility: more compact, cleaner. Even though there was a lot of controversy about applying interplanetary-engine technology to the Earth itself.’
