Question
Can you really save a glacier with a wool blanket?
Short answer
Not the whole glacier. Covering sections of ice with reflective or insulating material genuinely slows local melt, and alpine countries have actually done it for years on small patches. The film is upfront that this is a local measure, not a complete climate solution.
Where this answer comes from
Can you save a glacier with wool?
THAW follows Swedish adventurer Oskar Kihlborg as he covers part of a glacier on Kebnekaise with a wool blanket to slow its melting. Filmmaker Robin Danehav shot it across three separate trips in different seasons, and the film is honest about how uncertain the experiment is. It is free to watch on YouTube.
