Ice may release more iron than climate models predict
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. Roughly 17% of Earth's land surface sits on permafrost, and vast additional areas experience seasonal freezing.
