As the Arctic Warms, Soils Lose Key Nutrients

Javier Barbuzano, Science Writer by Javier Barbuzano 1 August 202526 August 2025

Climate change heats not only the air and the ocean but also the soil, where key processes that determine fertility and carbon sequestration operate in a fine-tuned balance.

Warming Winters Sabotage Trees’ Carbon Uptake

by Grace van Deelen 31 July 202531 July 2025

In temperate forests, the biomass-building benefits of warmer growing seasons are offset by damaging variability in winter weather—a disparity that climate models may miss.
