UCLA’s Department of Atmospheric & Oceanic Sciences (Division of Physical Sciences) offers an interdisciplinary Climate Science B.S. that trains students in the scientific basis of climate variability and human-induced climate change, climate risk assessment, and solution pathways. The core covers climate system phenomenology, energy flows, the hydrological cycle, large-scale circulation, climate data and modeling, plus quantitative and policy/solutions electives. Preparation includes sequences in chemistry, calculus, physics, statistics, computing, and introductory AOS, building strong analytical and computational skills for research, public/private sector decision support, and graduate study. The program is highlighted by UCLA Physical Sciences as a dedicated undergraduate climate degree. Third-party study portals describe the degree as a 4‑year, full-time, on‑campus program integrating atmospheric science, oceanography, geology, environmental science, and policy. 来源： https://atmos.ucla.edu/students/graduate/application/ https://admission.ucla.edu/apply/transfer/deciding-on-major/major-preparation-the-college/requirements-for-atmospheric-and-oceanic-sciences https://grad.ucla.edu/gasaa/deptinfo/deptinfo.asp?code=0349&academicyear=20252026 https://grad.ucla.edu/requirements/?app=admission&major=002E
