人口為國家基本要素之一，其組成、素質、分布、發展及遷徙等面向，關係國家之發展與社會福祉。越來越多的證據及研究顯示，今後的全球氣候變遷可能越來越嚴重，而氣候變遷將如何影響人口移動，將是個人生命與國家社會安全之嚴肅課題。 本研究首先闡述氣候變遷目前全球主要氣候變遷的現象及影響，如溫度及海平面的上升，再談臺灣觀察之主要氣候變遷的現象及影響，觀察是否有相同或相異的氣候變遷。其次，並分析目前全球移民主要趨勢與原因，同時討論包括氣候難民，並以氣候變遷在過去及今日實際案例討論氣候改變如何影響移民;再將對臺灣的移民啟示做一分析。 最後，氣候變遷的觀察及預估（重大影響及災難），將是決策者未來調適策略或政策（包含移民）之制定及施行重大挑戰。 Population is one of the basic elements of country.
