    Tera = 1000 gigas. Idk if they are doing a switch between metric and imperial tons as well but that difference is less than the margins of error anyways.

      my math must be really off then. (1/361.8 mm of sea-level rise per Gt of ice loss) * 1000 * 7.5 = 2713mm = 106.83 inches = 8.9 feet. and the global ocean hasnt risen that much.

        ( (1/361.8 mm of sea-level rise per Gt of ice loss) * 1000) * 7.5 = 20.73
