Swiss NGO trials wool blankets to slow glacier melt, early results promising

A Swiss NGO is testing biodegradable wool blankets as an alternative to synthetic covers for slowing glacier melt. Early results indicate wool can match synthetic materials in reducing ice loss, though the trial is at an early stage and scalability remains uncertain. This matters as it could offer a more sustainable mitigation tool for alpine glaciers, but its impact is localized and not a substitute for emissions cuts.
