35CLIMATE CHANGE REQUIRES
THE WORLD'S ATTENTION
We have known about climate change for decades. There is little doubt that Earth is getting warmer and warmer (see the graph)．(图略) 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？　
[参考译文]
气候变化需要全世界的关注
我们了解气候变化已有数十年之久了。毫无疑问，地球正变得越来越温暖 (如图)。海洋和大气变暖，以及冰层融化、海平面上升，都为全球气候急剧变化提供了依据。
[句式释解]
句 　“There is little doubt that ...”是固定句式，表示“毫无疑问……”，that 在此引导同位语从句。
句 　along with为介词短语，意为“与……一起”，连接两个并列成分作主语时，谓语动词的数要和along with前面的成分保持一致。　　　　
2013年，在挪威的北极圈斯瓦尔巴群岛的一个岛上， (人们) 发现了一只死亡的北极熊，这张新闻图片令许多人感到震惊。据发现北极熊尸体的科学家说，这只北极熊仅剩“皮包骨”。一位长期研究北极熊的专家说，从尸体的姿势看，这只北极熊像是饿死的。专家称，气候变化导致的海冰面降低意味着北极熊无法像以前那样捕食海豹，于是它只能长途跋涉去寻找食物。这一令人惊恐的案例反映了气温上升对地球生态造成的影响。
[句式释解]
句 　本句为复合句。其中“who found ...body”为 who引导的定语从句，修饰the scientists；“that remained of the polar bear”为that引导的定语从句，修饰all。
句 　此部分为不定式的完成式，表示先于谓语动词发生的动作。
句 　“that low ...find food”为that 引导的宾语从句。在宾语从句中，“caused by climate change”为过去分词短语作后置定语，修饰low sea-ice levels；“the bear ...as before”为省略了that的宾语从句。　　　　
那么，到底是什么导致全球平均地表温度上升的呢？气候科学家常常会提到一个关键的气候过程——“温室效应”；它有两个常见的含义：“天然”温室效应和“人造”温室效应。“天然”温室效应指的是来自太阳的热量以短波辐射的形式进入大气层，使地表变暖。这一热量以更大的波长被释放回大气层。大气层中甲烷、二氧化碳等温室气体困住了部分热量，从而使地球保持气候温暖、适宜居住。如果没有这一过程，地球就无法维系生命。然而，“人造”温室效应现在却成为一个大问题。当人类由于燃烧化石燃料产生了大量额外的温室气体时，更多的热能被困在大气层中，导致地表温度迅速上升。
　[句式释解]
句 　that引导的同位语从句，解释说明the fact的内容。
句 　此处的现在分词短语作结果状语。　　　
确凿、全面的证据表明，温度上升导致全球极端天气和自然灾害增多，不仅造成严重破坏，而且使人丧命。气候学家已发出警告：如果我们不采取适当的行动，这种变暖的趋势可能会持续下去，而我们将为此付出更大的代价。事实上，有关极端暴风雨和热浪造成死亡和经济损失的新闻报道已屡见不鲜。
　[句式释解]
句 　本句中“that the rise ...human lives”为that引导的同位语从句，解释说明strong and comprehensive evidence的内容。“not only causing ...human lives”为not only ...but also连接的两个现在分词短语作结果状语。
句 　此处为现在分词短语作后置定语，修饰extreme rainstorms and heatwaves。　　　　
温室气体的持续排放将导致全球气候进一步变暖，并带来持久的变化。这需要全世界人们的关注。各国政府需考虑制定政策并采取适当的行动和措施以减少温室气体的排放。作为个人，我们可以通过限制生活方式产生的二氧化碳量来减少我们的“碳足迹”。我们有责任抓住每一个机会，教育每个人了解全球变暖，包括其成因和影响，因为这是影响这个星球上我们所有人的最严重的问题。那么，你会做些什么来贡献力量呢？

课文标题“CLIMATE CHANGE REQUIRES THE WORLD'S ATTENTION”点明了作者的诉求：气候变化对地球生态系统的影响是巨大的，需要全人类共同关注和面对。作者首先使用统计图表直观展示气候变化的趋势，同时使用饿死的北极熊的例子和照片来具体说明气候变暖的影响，从而帮助读者初步感知气候变暖给地球带来的负面影响。文章第三段客观地探讨了气候变暖背后的原因；第四段分析了气候变暖的后果；文章的最后作者呼吁世界各国政府携起手来，共同制定政策，采取措施减少温室气体的排放。
阅读技巧：本文是一篇说明文，以现在时态和将来时态为主，强调文章的现实意义以及对将来不利后果的预测。与记叙文、议论文相比，说明文更强调科学性和客观性，一般不表达作者的感情倾向。
保护环境，人人有责
本文最后一句向读者提出问题So what will you do to help “那么，你会做些什么来贡献力量呢？”这不禁令每一位读者深思自己对环境保护的责任。大自然为人类提供了生存的资源环境。如果资源环境遭受破坏，那么人类生存发展的空间就会被破坏，所以保护环境就是保护人类自己。保护环境不仅可以促进经济的可持续发展，也能体现出个人修养与素质，是社会文明进步的标尺。因此，我们每一个人，都要从自身做起，成为有全球视野的有责任和担当的人。
请体会并记住下面的句子：
①Treat kindly the Earth is to treat kindly oneself.
善待地球就是善待自己。
②Cherish the source of nature, and totally make a living a life green.
珍惜自然之源，共营生命绿色。
③Everyone should remember that we have only one earth.
每个人都应该谨记，我们只有一个地球。
