Ice Loss Explained in Simple Terms

A beginner-friendly guide to ice loss, including sea ice, land ice, glaciers, ice sheets, reflectivity, meltwater, ecosystems, and why melting ice matters for people and nature.

What Causes Polar Ice to Melt?

Polar ice melts through several linked drivers, from warm air and ocean heat to soot, sunlight, rain, wind, melt ponds, and glacier flow.

The Science Behind Polar Ice Loss

Polar ice loss is measured through a web of satellites, fieldwork, ice cores, ocean observations, and models. Here is how scientists track the mass balance, feedbacks, and hidden forces reshaping Greenland and Antarctica.
