隨著文明社會之進步，大多數國家人民的生活，已比過往來的富足，生活也較為安全。冷戰結束後，全球化時代來臨，揭開國際秩序運作的新面貌，更強調在國際制度下的合作而非衝突。 在另一方面，國與國之間的往來漸趨頻繁，衍生出相當多新興的安全問題，並非軍事武器所能解決。人們也開始意識到安全問題的其他面向，社會的進步並不代表人類在各方面都能夠更加安全。氣候變遷議題既屬人類過度追求經濟成長之下，普遍忽略而逐漸使吾人生活品質下降的永續發展問題。是以本論文首先欲循人類安全之觀點，深究氣候變遷議題帶來哪些安全危機與影響，再從國際社會所建構的國際環境建制論其解決之道。 此外，本論文最後擬以2017 年6 月美國總統川普宣布退出《巴黎氣候協定》為例，提出未來在氣候變遷之因應上，若少了此一碳排放大國，前景是否不樂觀，從而探討此舉對於人類安全與環境安全之倡議，是否造成嚴重斲喪，以期能藉本論文闡明氣候變遷議題對於人類安全之重要性。 With the progress of a civilized society, the lives of the people in most countries are generally more prosperous and safer. After the end of the Cold War, globalization has unveiled the new face of the international order and emphasized cooperation under the international system rather than conflict. On the other hand, the interactions between countries are becoming more and more frequent, and many new security problems have emerged. It can’t be solved by military weapons. People start to realize that social progress doesn’t represent human can be more security in all aspects. The issue of climate change is not only a problem of sustainable development that humans have been pursuing under economic growth, but a result has generally neglected and caused down the quality of our life. Therefore, this paper would base on the viewpoint of human security and discuss the security crisis and impact brought by the climate change first. Then, it would try to find out the solution for the international regimes which was constructed by the international community. In addition, I would conclude by a case study of the United States withdrawal from the “Paris Agreement” announced by President Trump in June 2017.I took it as a case study for the purpose of explaining whether it is not promising in the prospect of fighting against climate change if the absence of this large carbon emission country. It would realize the cause of the promotion of human and environmental security, and hopefully, it could explain the importance of climate change on human security.
