New Research Shows Earth System Models Overestimate Carbon Removal Rate
26 Nov 2025 | Abstracted from Phys.org
New research shows Earth system models overestimate carbon removal because they assume nitrogen fixation rates about 50% higher than reality. Since plants need nitrogen to grow under elevated CO2, this error exaggerates the carbon fertilization effect by ~11%. Scientists urge revising models to reflect actual nitrogen fixation, warning that climate projections may be too optimistic about natural carbon uptake. |
