Over nearly five decades, Earth's polar ice sheets have surrendered more than 12 trillion tons of frozen mass to warming oceans — a transformation measured not in forecasts but in satellite-confirmed fact. From 1978 to 2025, instruments orbiting silently above Greenland and Antarctica have recorded what no single generation in human history has witnessed: the accelerating dissolution of reserves that took millennia to build. The consequence is not abstract — rising seas are already redrawing the boundaries between land and water, between home and displacement. What the data captures is less a

Rising sea levels from ice melt threaten displacement of coastal populations and island nations worldwide.
