Global warming全球变暖全英文介绍

One of the effects of global warming is the destruction of many important ecosystems.Changing and erratic climate conditions will put our ecosystems to the test, the increase in carbon dioxide will increase the problem. The evidence is clear that global warming and climate change affects physical and biological systems. There will be effects to land, water, and life. Already today, scientists are seeing the effects of global warming on coral reefs, many have been bleached and have died. This is due to warmer ocean waters, and to the fact that some species of plants and animals are simply migrating to better suited geographical regions where water temperatures are more suitable. Melting ice sheets are also making some animals migrate to better regions. This effects the ecosystems in which these plants and animals live. Several climate models have been made and they predict more floods (big floods), drought, wildfires, ocean acidification, and the eventual collapse of many ecosystems throughout the world both on land and at sea. There have been forecasts of things like famine, war, and social unrest, in our days ahead. These are the types of effects global warming could have on our planet. Another important effect that global warming will bring is the loss and endangerment of many species. Did you know that 30 percent of all plant and animal species alive in the world today are at risk of extinction by the year 2050 if average temperatures rise more than 2 to 11.5 degrees Fahrenheit. These mass extinctions will be due to a loss of habitat through desertification, deforestation, and ocean warming. Many plants and animals will also be affected by the inability to adapt to our climate warming.

Global Warming Section A 本文词数:302 参考时间:2'40'' Rising temperatures in coming years would lead to less sea ice in the Southern Ocean that surrounds Antarctica and fewer habitats and feeding grounds for penguins, says the World Wildlife Fund (世界自然基金会) in its report 2 Degrees is Too Much. Antarctica and the Arctic are the most threatened regions from climate change. In the Antarctica, the temperature has risen 2.5 degrees in the past 50 years. This speed is nearly five times faster than that before the Industrial Revolution. It is mainly caused by burning fossil fuels. Unless nations reduce carbon dioxide emission1, the world will warm by an average of 2 degrees in less than 40 years. Rich nations should agree to reduce greenhouse gas emission. Temperatures near the Poles have risen much faster, which has led glaciers2 on the Antarctic Peninsula to melt3 quickly. The situation is quite critical, because in the past 50 years the number of emperor penguins (帝企鹅) has decreased by 50 percent across the whole Antarctica. On the Antarctic Peninsula’s northwest coast, the number of Adelie penguins (阿德里企鹅) has dropped surprisingly over the past 25 years. Fifty percent of the habitats of the emperor penguin and 75 percent of the habitats of the Adelie penguin face a rapid reduction, or even disappearance, if the global temperature rises 2 degrees above pre-industrial levels. With a 2-degree increase in global temperature and the decrease in sea ice thickness, emperor penguins will find it difficult to find new areas to live. With less sea ice, penguins could be pushed further south, but this could prevent them from hunting for food during the dark winters, because they need at least a few hours of daylight to find their food. Notes: 1. emission n. 排放 2. glacier n. 冰川 3. melt v. 融化 词数:150处理时间:2′45″ Read the passage and then choose the best answer for each question. 1. The purpose of the passage is to _____.

Global Warming

Global Warming Global warming is the increase in the average temperature of the Earth's surface air and oceans.Climate change is any major change in measures of climate,such as temperature, rainfall and wind.Scientists have debated about global warming for years.Many have different opinions about the extent to which greenhouse gases are responsible for it.Greenhouse gases, such as carbon dioxide,are produced by factories, power stations and vehicles. They trap heat in the Earth's atmosphere.Research shows the level of carbon dioxide gas in the Earth's atmosphere has increased by more than 30% in the last 250 years.Carbon dioxide is produced by burning oil and coal.An increase in global temperatures has led to other problems.Scientists have observed a rise in sea levels and a melting of ice in the Earth's Polar areas.Scientists also believe that global warming is affecting endangered plants and animals,sea life and the seasonal activities of organisms.

Global Warming 原因 中英对照

原因分析 人为因素 1.人口剧增因素Dramatic increase in the population 人口的剧增是导致全球变暖的主要因素之一。同时,这也严重地威胁着自然生态环境间的平衡。这样多的人口,每年仅自身排放的二氧化碳量就将是一惊人的数字,其结果就将直接导致大气中二氧化碳的含量不断地增加。 The population factor is one of the main reasons in global warming. At the same time, this is a serious danger to the balance between naturalenvironment. So large the population is, each year only the amounts of their own carbon dioxide emissions would be a staggering figure. And this result will lead directly to the increaseof carbon dioxidein the atmosphere. 2.大气环境污染因素Environmental factors 环境污染的日趋严重已构成一全球性重大问题,同时也是导致全球变暖的主要因素之一。21世纪,关于全球气候变化的研究已经明确指出了自上个世纪末起地球表面的温度就已经开始上升。 Nowadays environmental pollution has turned major global problem, also lead to global warming. Now, global climate change research has clearly pointed out that since the end of last century , the Earth's surface temperature has begun to increase . 3.海洋生态环境恶化因素Deterioration of the marine environment factors 海平面的变化是呈不断地上升趋势,根据有关专家的预测到下个世纪中叶,海平面可能升高50cm。如不采取及对措施,将直接导致淡水资源的破坏和污染等不良后果。 At present, the sea-level was constantly on the rise, according to the experts forecast ,at the middle of the next century, sea levels could rise by 50cm. And if we do not take measures, that will lead to the damage and pollutionof fresh water resources . 4.土地遭破坏因素The land damage factors 众所周知良好的植被能保持水土流失。但人类活动由于为获取木材而过度砍伐森林、开垦土地用于农业生产以及过度放牧等原因,仍在对植被进行着严重的破坏,可能造成大范围洪涝灾害和沙尘暴,给社会造成重大经济损失,并恶化生态环境。 As is known to all, a good vegetation can prevent the soil and water loss. But due to human activities to get wood and cut down forest, cultivate land for agricultural production, there is still much serious damage to vegetation. And it can cause floods and dust storms, cause great economic loss to the society and worsen natural environment. 5.森林资源锐减因素the sharp drop in forest resources factor

Unit 8 Focus on Global Warming John Weier Twenty-five years ago if you made a trip to the local library and perused the periodical section for articles on global warming, you’d probably have come up with only a few abstracts from hardcore science journals or maybe a blurb in some esoteric geopolitical magazine. As an Internet search on global warming now attests, the subject has become as rooted in our public consciousness as Madonna2 or microwave cooking.1 Perhaps all this attention is deserved. With the possible exception of another world war, giant asteroid, or an incurable plague, global warming may be the single largest threat to our planet.2 For decades human factories and cars have spewed billions of tons of greenhouse gases into the atmosphere, and the climate has begun to show some signs of warming. Many see this as a harbinger of what is to come.3If we don’t curb our greenhouse gas emissions, then low-lying nations could be awash in seawater, rain and drought patterns across the world could change, hurricanes could become more frequent, and El Ninos could become more intense. Our Warming Planet What has worried many people now is that over the past 250 years humans have been artificially raising the concentration of greenhouse gases in the atmosphere. Our factories, power plants, and cars burn coal and gasoline and spit out a seemingly endless stream of carbon dioxide. We produce millions of pounds of methane by allowing our trash to decompose in landfills and by breeding large herds of methane-belching cattle. Nitrogen-based fertilizers, which we use on nearly all our crops, release unnatural amounts of nitrogen oxide into the atmosphere. Once these carbon-based greenhouse gases get into the atmosphere, they stay there for decades or longer. According to the Intergovernmental Panel on Climate Change (IPCC)since the industrial revolution, carbon dioxide levels have increased 31 percent and methane levels have increased 151 percent. Paleoclimate readings taken from fossil records show that these gases, two of the most abundant greenhouse gases, are at their highest levels in the past 420,000 years. Many scientists fear that the increased concentrations of greenhouse gases have prevented additional thermal radiation from leaving the Eart h. In essence, these gases are trapping excess heat in the Earth’s atmosphere in much the same way that a windshield traps solar energy that enters a car.4 Much of the available climate data appear to back these fears.5Temperature data gathered from many different sources all across the globe show that the surface temperature of the Earth, which includes the lower atmosphere and the surface of the
