Скачать или смотреть From Ancient Ice to Satellites: How Glaciers Are Disappearing 🏔️

Glaciers may look permanent, but history and modern science show otherwise.

In 1991, the retreat of an Alpine glacier revealed Ötzi the Iceman, a man who had been frozen for more than 5,000 years. His discovery was not planned — it happened because ice that had remained stable since prehistory had retreated.

That moment is part of a much larger story.

In this video, we explore how scientists track glacier loss — from early historical observations in the Alps to modern satellite-based measurements that monitor glaciers worldwide.

You’ll learn:

How glacier retreat was documented before satellites
How missions like Landsat Program, Sentinel-1, ICESat-2, and GRACE-FO measure glacier change
How scientists calculate glacier mass loss using elevation, radar, gravity, and field data
What satellite records show about global glacier decline since 2000
Why glacier melting matters for sea level rise, water resources, and natural hazards

This is not about symbols or slogans.
It’s about measured change, observed repeatedly and independently over decades.

Glaciers are disappearing slowly, but measurably — within a single human lifetime.
