根據大多數科學家的說法，過去 100 年來地球大氣層溫度升高了約 1.4 華氏度。 結果是冰川融化、海平面上升和更多極端天氣事件。 有人說，目前的氣候變遷是地球變遷自然循環的一部分。 然而，許多科學家認為，由於大氣中溫室氣體的增加，地球氣候正在改變。 氣候變遷研究了世界各國如何採取保護措施等措施來減輕氣候變遷的影響。
According to most scientists, Earth's atmosphere has warmed by about 1.4 degrees Fahrenheit in the past 100 years. The result has been melting glaciers, rising sea levels, and more extreme weather events. Some people say that current climate change is part of the natural cycle of changes on Earth. Many scientists, however, think that Earth's climate is changing because of increased greenhouse gases in the atmosphere. Climate Change examines how countries around the world are taking steps, such as conservation, to lessen the effects of climate change.
