Ice may release more iron than climate models predict

Most people think of ice as frozen and lifeless, but research at Umeå University shows the opposite. A new study published in the Proceedings of the National Academy of Sciences demonstrates that ice actively speeds up the breakdown of iron minerals and may release more iron than current environmental models account for. This is crucial for predicting how nutrient cycles, carbon storage, and water quality will change in polar and mountain regions as the planet warms.
