9、 THE WORLDS ATTENTION We have known about climate change for decades.There is little doubt that Earthis getting warmer and warmer (see the graph). A warming ocean and atmospherealong withmelting ice and rising sea levels provide evidence of a dramatic change in the global climate. In 2013, a lot of
10、people were shocked by a news photo of a dead polar bear that was found on Norways Arctic island of Svalbard.According tothe scientists who found its dead body, all thatremained ofthe polar bear wasskin and bones . An expert who has studied polar bears for many years said that from the position of i
11、ts dead body, the bear appeared to havestarvedand died. Expertsclaimed that low sea-ice levels caused by climate change meant thatthe bear could not hunt seals as before, so it had to travel greater distancesin order tofind food. This alarming case showed how the increase in temperaturehad an impact
12、 onEarthsecology.Then what is causing the increase in the global average surface temperature? Climate scientists often mention a key climate process called thegreenhouse effect which has two common meanings: thenatural greenhouse effect and theman-made greenhouse effect. Thenatural greenhouse effect
13、refers tothe fact that heat from the sun enters the atmosphere and warms Earths surface as short-wave radiation. The heat isreleasedback into space at longer wave lengths. Greenhouse gases in the atmosphere, such as methane andcarbondioxide, trap some of the heat, keeping Earths climate warm and hab
14、itable. Without this process, Earth could notsustainlife. However, theman-made greenhouse effecthas now become a big problem. When people produce huge amounts of extra greenhouse gases by burning fossilfuels, more heat energy is trapped in the atmosphere and causes Earths surface temperature to rise
15、.There is strong andcomprehensiveevidence that the rise in temperature hasled toan 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
16、 will probably continue and there will be a higher price to pay. In fact, news reports arefrequentlybroadcastabout extreme rainstorms and heatwaves causing deaths and economic losses.Continued greenhouse gas emissions willresult infurther warming and long-lasting changes to the global climate. This
17、requires the attention of people all over the world. Governments need to consider makingpoliciesand taking appropriate actions and measures to reduce greenhouse gas emissions. We as individuals can also reduce ourcarbon footprintbyrestrictingthe amount of carbon dioxide our lifestyles produce. It is our responsibility toseizeevery opportunity to educate everyone about global warming,along withits causes and impacts, because this is the most serious issue affecting all of us on this planet. So what will you do tohelp?（素材来源：2019人教版高中英语教材选必三 Unit3）
