The power density of nanotech is extremely high (10 kW/kg), so it only takes 16 kilograms of active nanotech per person * 10 billion people to generate enough waste heat to melt the polar ice caps. Literally boiling the oceans should only be a couple more orders of magnitude, so it’s well within possible energy demand if the AIs can generate enough energy. But I think it’s unlikely they would want to.
