Glaciers and ice sheets, like other biomes, occupy a significant area of the planet and
harbour biological communities with distinct interactions and feedbacks with their physical …

The cycling of carbon on Earth exerts a fundamental influence upon the greenhouse gas
content of the atmosphere, and hence global climate over millennia. Until recently, ice …

Contamination by plastic debris has been documented in most regions of the world, but their
occurrence in high mountain areas has not been investigated to date. Here we present the …

Natural dust is often associated with hot, subtropical deserts, but significant dust events have
