There won't be an ice sheet, it will melt within the next ten thousand years due to global warming. Sea levels are expected to rise four meters during this period. Humans need to leave Earth long before the Sun turns into a red giant. We have about 300 million years to leave the planet or it is game over. Many distinct areas of Earth such as the Grand Canyon will have eroded away in about 2-3 million years. Mountain ranges like the Rockies will be gone in 50 million years. The Hawaiian Islands will disappear into the ocean in 80 millions years as the Pacific Plate recycles its land mass. In 300 millions years, the Sun will change its luminosity, increasing the amount of solar radiation reaching the Earth. This will increase the mean solar temperature by 5C degrees. A little over 300 million years, give or take a few million years, all the continents are going to merge into one super continent. On the plus side, it is expected this will bring a new glacial period: increasing oxygen levels, lowering global temperatures, create new sea ice, and lowering sea levels due to global cooling. In 500 million years the Sun's luminosity will be so great that it will disrupt the carbonate–silicate cycle. The higher luminosity increases weathering of surface rocks, which traps carbon dioxide in the ground as carbonate. As water evaporates from the Earth's surface, rocks harden, causing plate tectonics to slow and eventually stop once the oceans evaporate completely. Without volcanoes to recycle carbon into the Earth's atmosphere, carbon dioxide levels fall to the point where photosynthesis is no longer possible. Good luck in the bunker.
