"More than 26,000 years ago, sea level was much lower than it is today partly because the ice sheets that jut out from the continent of Antarctica were enormous and covered by grounded ice—ice that was fully attached to the seafloor."
"Ice dominates both polar regions but in different ways. The Arctic is a frozen ocean surrounded by land. Antarctica, by contrast, is a frozen landmass surrounded by ocean."
"Several companies turned back or rerouted Arctic sailings after the open-water conditions of the past several years gave way to relatively heavy ice."
"The largest glacier in Greenland has lost more ice in the last 15 years than it did in the previous 100, shedding 10 miles worth of ice into the sea."
