Science — examined the loss of ice from Greenland, Antarctica and smaller glaciers and ice caps around the world. The study considered
chunks of ice falling into the oceans — from glaciers and ice sheets — and floating, as well as ocean expansion due to rising water temperatures.
about to get more than about two meters of sea-level rise in the next century." He added: "The real unknown right now is what we call the

Venice could be inundated.
