20 世纪中期以来，地球的平均温度持续升高。科学家们认为，气温升高是由消耗矿物燃料和砍伐森林造成温室气体不断聚集而引起的。反对者们则提出，地球的温度是自然变化的。但是我们必须意识到，气温升高会使海平面因冰川融化而上升，改变降水模式和极端天气情况发生的频率和强度，并会影响农业和人类的生存。气候变化问题事关人类的福祉和全球的可持续发展，需要国际社会共同积极响应。 目前，多数国家都赞同应对全球变暖的解决方法是实施应对气候变化的法规，减少大气中的问温室气体排放

The Earth's average temperature has been increasing since the mid-20th century. Scientists believe that the temperature increase is cuased by increasing concentrations of greenhouse gases from the burning of fossil fuel and deforestation. Opponents propose that the Earth's emperature naturally fluctuates. But we must be aware that the elevated temperature will cause sea levels to rise due to melting glaciers, change the pattern of precipitation as well as the frequency and intensity of extreme weather events, and will affect agriculture and survival of human beings. The issue of climate change calls for common and active responses from the international community, as it concerns the well-being of all people and the global sustainable development. Now most countries agree that the solution to global warming includes enacting climate change legislation and reducing emissions of greenhouse gases into the atmosphere.
