| Under an intermediate future-warming scenario, the study projected that cloud-condensation-nuclei concentrations associated with new-particle-formation activity could increase by 3–16% in the High Arctic but decline by 15–31% in the Maritime Arctic by 2090–2100. | FORECAST | Not assessed | — | 1 of 4 | 78 |
| A harmonized Arctic aerosol analysis using observations spanning 2003–2024 identified three regimes with contrasting contributions of new particle formation to cloud condensation nuclei populations: the High Arctic, Maritime Arctic and Continental Arctic. | OBSERVATIONAL | Insufficient evidence | — | 1 of 4 | 119 |
