Swiss Researchers Test Sheep's Wool Blankets to Slow Glacier Melting

Swiss scientists are experimenting with natural wool blankets as a way to reduce ice melt on glaciers. The blankets are made from discarded sheep's wool, repurposing an agricultural byproduct that would otherwise go to waste. Trial results suggest the eco-friendly coverings perform comparably to synthetic alternatives. However, researchers caution that the method only addresses melting in localized areas and cannot reverse the broader effects of climate change. Long-term glacier preservation, they stress, ultimately depends on reducing greenhouse gas emissions.
