Ice Sheet
An ice sheet is a vast, thick layer of ice that blankets a large land area, typically spanning more than 50,000 square kilometers and flowing outward from a central high point. These frozen giants act as Earth's natural refrigerators, influencing global weather patterns and sea levels, but their rapid melting in recent decades highlights the urgent threats posed by climate change.
Did you know?
The Antarctic Ice Sheet alone holds enough ice to raise global sea levels by about 58 meters if it melted completely, which would submerge major coastal cities like New York and London. This staggering volume represents roughly 60% of the world's fresh water, underscoring how these frozen expanses have shaped human history and migration patterns for millennia.
