RESEARCH BRIEFINGS 13 November 2024 Whether rising carbon dioxide concentrations affect terrestrial species diversity around the globe is, surprisingly, almost unstudied. A 24-year field experiment shows that adding nitrogen to grassland plots reduces species richness, and that increasing the level of carbon dioxide amplifies this effect, tripling the reductions caused by nitrogen addition.

Current estimates of the CO₂ from the atmosphere that disappears in the ocean, commonly referred to as the ocean CO₂ sink, suggests that […]
