The tundra, a critical carbon sink, is undergoing significant changes due to the warming climate. Traditionally known to store carbon, these vast, cold landscapes are now releasing it, potentially exacerbating climate change. This shift is the focus of a recent comprehensive study that delves into how the warming climate affects carbon dynamics in tundra regions across the globe. Warming effect on tundra sites To explore this phenomenon, a diverse team of 70 scientists from various countries embarked on an ambitious project. They implemented open-top chambers (OTCs) at...
