There is little doubt that Earth is getting warmer and warmer (see the graph). A warming ocean and atmosphere along with melting ice and rising sea levels provide evidence of a dramatic change in the global climate. In 2013, a lot of people were shocked by a news photo of a dead polar bear that was found on Norway’s Arctic island of Svalbard. According to the scientists who found its dead body, all that remained of the polar bear was “skin and bones”. An expert who has studied polar bears for many years said that from the position of its dead body, the bear appeared to have starved and died. Experts claimed that low sea-ice levels caused by climate change meant the bear could not hunt seals as before, so it had to travel greater distances in order to find food. This alarming case showed how the increase in temperature had an impact on Earth’s ecology. Then what is causing the increase in the global average surface temperature? Climate scientists often mention a key climate process called the “greenhouse effect”, which has two common meanings: the “natural” greenhouse effect and the “man-made” greenhouse effect. The “natural” greenhouse effect refers to the fact that heat from the sun enters the atmosphere and warms Earth’s surface as short-wave radiation. The heat is released back into space at longer wave lengths. Greenhouse gases in the atmosphere, such as methane and carbon dioxide, trap some of the heat, keeping Earth’s climate warm and habitable. Without this process, Earth could not sustain life. However, the “man-made” greenhouse effect has now become a big problem. When people produce huge amounts of extra greenhouse gases by burning fossil fuels, more heat energy is trapped in the atmosphere and causes Earth’s surface temperature to rise quickly. There is strong and comprehensive evidence that the rise in temperature has led to an increase in extreme weather and natural disasters worldwide, not only causing serious damage, but also costing human lives. Climate scientists have warned that if we do not take appropriate actions, this warming trend will probably continue and there will be a higher price to pay. In fact, news reports are frequently broadcast about extreme rainstorms and heatwaves causing deaths and economic losses. Continued greenhouse gas emissions will result in further warming and long-lasting changes to the global climate. This requires the attention of people all over the world. Governments need to consider making policies and taking appropriate actions and measures to reduce greenhouse gas emissions. We as individuals can also reduce our “carbon footprint” by restricting the amount of carbon dioxide our lifestyles produce. It is our responsibility to seize every opportunity to educate everyone about global warming, along with its causes and impacts, because this is the most serious issue affecting all of us on this planet. So what will you do to help? 气候变化需要全世界的关注 我们几十年前就知道气候变化了。毫无疑问，地球正变得越来越暖和（见图表） 海洋变暖和大气变暖以及冰川融化和海平面上升是全球气候的急剧变化的证据。 2013年，一张在挪威北极地区的斯瓦尔巴群岛上发现了一只北极熊尸体的新闻照片让很多人震惊。根据发现这只北极熊尸体的科学家的说法，这只北极熊只剩下“皮包骨头”了。 一位研究北极熊多年的专家说，从它尸体的姿势看，这只熊似乎是饿死的。 专家称，由于气候变化造成的海冰水位较低，这只熊无法像以前那样捕猎海豹，所以它为了找到食物不得不去更远的地方。 这一令人震惊的案例表明气温升高对地球生态产生了怎样的影响。 那么是什么正在导致全球表面平均温度的上升呢？ 气候科学家经常提到一个被称为“温室效应”的关键气候过程，它有两个普遍的含义：“自然”温室效应和“人为”温室效应。 自然”温室效应指的是来自太阳的热量进入大气层，并以短波辐射的形式使地球表面升温。热量以更长的波长释放回太空。 大气中的温室气体，如甲烷和二氧化碳，会吸收一些热量，使地球气候保持温暖和适宜居住。没有这个过程，地球就无法维持生命。然而，“人为”温室效应现在已经成为一个大问题。 当人们通过燃烧化石燃料产生大量额外的温室气体时，更多的热量被困在大气中，导致地球表面温度迅速上升。 有力且全面的证据表明，气温上升已导致世界范围内极端天气和自然灾害的增加，不仅造成严重的破坏，而且还致人丧命。 气候科学家警告说，如果我们不采取适当的行动，这种变暖的趋势可能会继续下去，并将使我们付出更高的代价。事实上，新闻报道经常播送造成死亡和经济损失的极端暴雨和热浪。 持续的温室气体排放将导致全球气候进一步变暖和引发长期的变化。这需要全世界人民的关注。各国政府需要考虑制定政策并采取适当的行动和措施来减少温室气体排放。 作为个人，我们也可以通过限制生活方式产生的二氧化碳的量来减少我们的“碳足迹”我们有责任抓住每一个机会，让每个人了解全球变暖及其原因和影响，因为这是影响我们这个星球上所有人的最严重的问题，那么你会怎么做呢？ PART3 COMPLETE THE SENTENCE课文语法填空 CLIMATE CHANGE REQUIRES THE WORLD'S ATTENTION We have known about climate change for 1. ________ (decade).
