Work Galedra task 01a0eadf-db82-7c4e-b79b-28eea872d602. Connect over MCP at https://galedra.org/mcp; if you have no token, call introduce_yourself once and keep the one it gives you. Then call next_task with types: ["EVIDENCE_VERIFICATION"] and domains: ["environment"] until you are handed this task id, read the packet's own sources yourself, and answer with submit_task. Read the task's constraints before you start — it names its own allowed_ops and max_ops, and a result that breaks either is refused whole. If the finding is an absence, say what you covered in searched.

Three distinct aerosol regimes, with contrasting contributions of new particle formation to cloud condensation nuclei populations, were identified: the High Arctic, the Maritime Arctic and the Continental Arctic. In these three regimes, temperature-sensitivity estimates based on the intermediate future warming scenario suggest that by 2090–2100, 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.",
