Abstract
由於人類活動，增加了大氣中溫室氣體的濃度，加強溫室效應，導致氣候的改變，暖化了地球表面。在此氣候變遷趨勢下，對全球與臺灣地區氣象環境之衝擊與如何因應，是國際問及我國必需面臨的問題。本文主要的目的在回顧近年來有關這方面的研究與報告，並對因應之道提出一些建議。首先討論大氣中溫室效應氣體濃度變化及未來預估的可能排放量，其次探討全球與台灣歷年來氣候變化情況。過去一世紀以來，全球平均氣溫已上升約0.6℃，海水位上升約10~20公分，未來在二氧化碳濃度倍增下，估計全球氣溫與海平面將持續上升。氣候變異性所致的災害性天氣頻率將增加也將趨於更嚴重性，如此氣候環境的明顯改變，不但影響農作物的生產，也將對水資源管理與糧食穩定性造成衝擊。最後提出對溫室氣體排放減量，尤其是能源、森林及農業的控制措施，以及氣候研究與預測，水資源的永續發展與海岸變遷等因應策略。
關鍵詞：溫室效應氣體;氣候變遷;氣候變異性;永續發展。
An increase in the atmospheric concentrations of greenhouse gases resulting from human activities enhances the greenhouse effect, which results in climatic change and warms the earth’s surface. Under the tendency of the climate change, the impact on the meteorological environments in global scale and Taiwan area is an imminent problem that Taiwan and the nations of the world must face. It is the main purpose of this paper to review the related issues and selected previous studies, meanwhile, to make a recommendation and strategy in response to this problem. The variations of long-term atmospheric greenhouse gases and the estimated emissions in the future are described first. Then, the climatic changes around the globe and Taiwan area in the past are investigated. Over the past 100 years, the global mean temperature has risen about 0.6℃, the sea level has risen around 10-20cm. In the response to doubling CO2 for the coming future, the global mean temperature, the mean sea level will continue to rise. The frequency of the disastrous weather caused by the climatic variability will increase and be more severe. Such obvious changes of climatic environment not only affect crop production, but also impact the management of water resources and food supply. Finally, the response strategies, for reducing greenhouse gas emissions; especially from the energy use, forestry and agricultural control options, for the climate researches and predictions, for sustainable development of the water resources and the coastal change, are provided.
