A Two‐Fold Increase of Phosphorus in Alpine Ice Over the Twentieth Century: Contributions From Dust, Primary Biogenic Emissions, Coal Burning, and Pig Iron Production
Abstract Phosphorus (P) is a key nutrient for many organisms but its global atmospheric budget is largely unconstrained. Estimates of major emissions sources such as fossil‐fuel combustion range from ∼0.02 to 1.1 Tg yr −1 , and primary biogenic emissions range from 0.16 to 1.0 Tg yr −1 . Here we use...
