The frozen soils of the Arctic hold a ticking climate bomb. New research reveals that warming temperatures are depleting vital nitrogen from Arctic soils, triggering an irreversible increase in carbon dioxide emissions that could accelerate global climate change. A decade-long study led by researcher Sara Marañón from the Universitat Autònoma de Barcelona (UAB) and CREAF has discovered that rising Arctic temperatures don’t just activate soil microorganisms that release CO2 – they also cause significant nitrogen loss, crippling plants’ ability to offset these emissions. “We already knew that climate change was causing Arctic soils to release more CO2, but we thought … Continue reading Arctic Warming Depletes Soil Nitrogen, Making CO2 Reductions Impossible as Plants Struggle
