Rapid Ice Retreat // Alaska, USA
A majestic river of ice turning into water. The Columbia Glacier is one of the most rapidly changing environments on Earth. Since 1980, it has retreated more than 20km, shedding icebergs into Prince William Sound at an alarming rate. This process is not just a local phenomenon — it is a global barometer for the health of our cryosphere.
The retreat of the Columbia Glacier is a dramatic visual testament to a warming planet. As the ice thins and pulls back, it reaches deep underwater valleys, accelerating its collapse. This "tidewater glacier cycle" is now permanently out of balance, contributing significantly to global sea-level rise.
