Most people think of ice as frozen and lifeless, but research at Umeå University shows the opposite. A new study published in PNAS 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.

Lakes play a vital filtering role in the ecosystem: they remove excess nitrogen from the water. An international research team led by the University of Basel and Eawag has now shown that climate change could weaken this natural purification process. This would have consequences extending all the way to coastal marine ecosystems.

In a major legislative move, China has adopted its first comprehensive Ecological and Environmental Code (EEC), a unified legal framework designed to address the interconnected global crises of climate change, biodiversity loss, and pollution. A commentary in the journal Carbon Research analyzes the significance of this new code, which takes effect on August 15, 2026. Authored by Jin Ma, Xiaoli Zhao, and Fengchang Wu from the Chinese Research Academy of Environmental Sciences, the piece outlines how the EEC provides a systematic legal solution for sustainable development and offers a new model for global environmental governance.

For decades, China’s environmental laws were fragmented across numerous statutes and regulations, a common challenge for many nations. The new EEC addresses this by systematically integrating more than 30 national laws and over 1,000 local regulatory documents into a single, coherent system. This “moderate codification” approach balances legal stability with the flexibility needed to address new environmental challenges, moving governance from passive, end-of-pipe remediation to proactive source prevention and control.
