    CLIMATE 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).[1] A warming ocean and atmosphere along with melting ice and rising sea levels provide evidence of a dramatic change in the global climate.

    [1]There is no doubt that...……不容置疑的。

    In 2013,a lot of people were shocked by a news photo of a dead polar bear that was found on[2] 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 bonesAn expert who has studied polar bears for many years said that from the position of its dead body[3],the bear appeared to have starved and died. Experts claimed that low sea­ice 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.

    [2]that引导定语从句修饰a dead bear。

    [3]who引导定语从句修饰an expert;that引导宾语从句。

    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[4]: the “natural” greenhouse effect and the “man­made” greenhouse effect. The “natural” greenhouse effect refers to the fact that heat from the sun enters the atmosphere and warms Earth's surface as short­wave radiation[5].The heat is released back into space at longer wave lengths. Greenhouse gases in the atmosphere,such as methane and carbon dioxidetrap some of the heat,keeping Earth's climate warm and habitable. Without this process,Earth could not sustain life. However,the man­made 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.

    [4]called...是过去分词短语作定语;which引导非限定性定语从句。

    [5]that引导同位语从句解释the fact。

    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[6].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.

    [6]that引导同位语从句解释evidence;causing和costing在句中作结果状语。

    Continued greenhouse gas emissions will result in further warming and long­lasting 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

    我们已经知道气候变化几十年了。毫无疑问地球正变得越来越暖和(如图所示)。海洋和大气的变暖冰的融化和海平面的上升为全球气候的剧烈变化提供了证据

    2013挪威北极斯瓦尔巴特岛发现一只北极熊死亡的新闻照片令很多人震惊。据发现其尸体的科学家称北极熊仅存的只是“皮包骨头”。一位研究北极熊多年的专家说从北极熊尸体的位置来看北极熊似乎是饿死的。专家称由于气候变化导致的海洋冰川位置低意味着这只熊不能像以前那样捕猎海豹因此它必须走更远的距离才能找到食物。这一令人担忧的案例表明温度的升高是如何影响地球生态的。

    那么是什么导致了全球平均地表温度的上升呢?气候学家经常提到一个关键的过程叫作温室效应它有两个共同的含义:自然温室效应和人为温室效应。自然温室效应是指太阳产生的热量以短波辐射的形式进入大气并使地球表面变暖。热量以较长的波长释放回太空。大气层中的温室气体如甲烷和二氧化碳捕获了一些热量保持了地球气候的温暖和宜居。没有这个过程地球就无法维持生命。然而人为的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能被困在大气中导致地球表面温度迅速上升。

    有确凿而全面的证据表明气温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造成人员伤亡。气候科学家警告说如果我们不采取适当的行动这种变暖趋势可能会继续下去并将付出更高的代价。事实上有关极端暴雨和热浪造成死亡和经济损失的新闻报道经常播出。

    温室气体排放量的持续增加将导致进一步变暖和全球气候的长期变化。这需要全世界人民的关注。各国政府需要考虑制定政策采取适当行动和措施减少温室气体排放。我们作为个人也可以通过限制我们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大家认识全球变暖及其原因和影响因为全球变暖是影响我们地球上所有人的最严重问题。那么你会做些什么来帮忙呢?
