Many experts agree that the most pressing problem facing all of us is that

of the gradual warming of the earth's atmosphere caused mainly by the 1_________ of carbon dioxide and CFCs production what has become known as

the 2_________effect. Informed opinion is that the atmosphere is getting warmer. In the past 80 years the 3__________ has increased by half of one degree Celsius.

The consequences are likely to be significant. Some experts predict that by 2090, the average temperature could be higher than today (by 2-6 ⁰ C). Good news, you may think, but there would be a price to pay. Global warming would affect the climate in all parts of the world. Low-lying coastal regions would be flooded because of ice melting. Hot countries which are already suffering from 4 could get even hotter and drier, and more arid.

Burning 5__________ (coal, gas and oil) is one of the main causes of global warming. When they are burned oxygen is used and carbon dioxide is produced. Trees that are growing use 6___________ and produce oxygen. So there could be a healthy balance. But since the industrial revolution about 150 years ago — the 7___________has been upset as more fossil fuels have been burned and forests cut down and burned at an unprecedented rate. The great amounts of C02 in the atmosphere are responsible for trapping more heat — the so-called 'greenhouse effect'. Other important 'greenhouse gases' are 8______________(chlorofluorocarbons), some of which are 10,000 times more powerful that carbon dioxide in trapping heat in the earth's atmosphere.

Проблемы взаимодействия общества и природы, хозяйственной деятельности человека и ее влияния на природную среду существовали всегда. Однако размеры влияния были локальными и не сказывались на глобальном уровне, не создавали угрозу существованию биосферы.

 Резкий перелом наступил во второй половине XX в. Впервые человечество оказалось перед угрозой уничтожения среды своего обитания. Локальные изменения в природных системах стали перерастать в глобальные — нарушение озонового слоя атмосферы, гибель лесов, глобальное потепление климата, сокращение видового разнообразия. Многие процессы грозят стать необратимыми.

Современный экологический кризис в значительной степени объясняется тем, что на протяжении многих веков развития человечества ведущим был принцип неограниченного экономического роста. Это привело к истощению природных ресурсов, ухудшению среды обитания.

Деградация природной среды идет по нескольким направлениям: загрязнение атмосферного воздуха; загрязнение природных поверхностных и подземных вод; изменение растительного покрова; снижение численности многих промысловых зверей и птиц, амфибий и рептилий, насекомых-опылителей, многих промысловых беспозвоночных.

 

                               Text 2 The Planet in Peril

Read the following text. Translate the underlined passage(s) into Russian.

The threat to the planet from global warming is clear. Fortunately, so are the solutions. Despite what naysayers claim – that energy-use patterns cannot be altered to any great extent – real change is possible given the political will to enact it. If such change is not enacted, however, pessimistic prophecies become self-fulfilling, especially with government subsidies and intensive efforts by special-interest groups to prevent the public from becoming well-informed.

In reality, an alternative scenario is possible – and the US could take the lead. In response to oil shortages and price rises in the 1970s, the US controlled its energy use by requiring an increase from 13 to 24 miles per gallon in the auto-efficiency standard. Economic growth was decoupled from growth in the use of fossil fuels, and the efficiency gains were felt worldwide. Global growth of CO2 emissions slowed from more than 4 percent each year to between 1 and 2 percent growth each year.

The US maintained the slower growth rate despite lower energy prices. Yet the US is only half as efficient in energy use as Western Europe, which encourages efficiency by fossil-fuel taxes. China and India, using older technologies, are less energy-efficient than the US and have a higher rate of CO2 emissions.

Available technologies could improve energy efficiency, even in Europe.              

  Economists agree that the potential could be achieved most effectively by a tax on carbon emissions, although only strong political leadership could persuasively explain the case for such a tax to the public. The tax could be revenue-neutral. Consumers who make a special effort to save energy could gain; well-to-do consumers who insist on three Hummers would pay for their excess.

Achieving a decline in CO2 emissions faces two obstacles: the huge number of vehicles that are inefficient in using fuel, and continuing CO2 emissions from power plants. Automakers oppose efficiency standards, prominently advertising their most powerful vehicles, which yield the greatest short-term profits. Coal companies want new coal-fired power plants built soon, assuring their long-term profits.     

The world must delay construction of new coal-fired power plants until the technology needed to diminish CO2 emissions is available. In the interim, new electricity requirements should be met with renewable energies. Much could be done to limit emissions by improving fuel-efficiency standards in buildings and appliances. Such improvements are entirely possible, but require strong leadership.

The Kyoto Protocol encouraged developed countries to decrease emissions slowly early in this century and extended help to the developing countries for adopting "clean" energy technologies that limit the growth of their emissions. Delays in that approach – especially US refusal to participate in Kyoto and improve vehicle and power-plant efficiencies – and the rapid growth in the use of dirty technologies resulted in an increase of 2 percent per year in global CO2 emissions during the past ten years. If such growth continues another decade, emissions in 2015 will be 35 percent greater than they were in 2000.

Any responsible assessment of environmental impact must conclude that further global warming exceeding 2 degrees Fahrenheit is dangerous. Yet because of the warming bound to take place, from continuing long-term effects of greenhouse gases and energy systems now in use, the world will exceed the 2-degree limit unless a change in direction begins this decade.

The public can act as our planet's keeper. The first human-made atmospheric crisis emerged in 1974, when chemists reported that chlorofluorocarbons (CFCs) might destroy the stratospheric ozone layer that protects the Earth from the sun's ultraviolet rays. Production of CFCs increased 10 percent per year for decades. If this business-as-usual growth of CFCs had continued just one more decade, it would have caused a larger greenhouse effect than CO2.

Instead, the media reported chemists’ warning, and consumers boycotted goods containing CFCs. Annual growth of CFC usage plummeted to zero. The principal CFC manufacturer developed alternatives. As a result, CFC use is decreasing. The ozone layer will recover.

Yet the same scientists and political forces that succeeded in controlling the threat to the ozone layer now fail to control the global-warming crisis. There are multiple reasons for that but one of the basic causes is that the government fails to provide leadership necessary to alter the situation.

Leaders with a long-term vision would place value on developing efficient energy technology and sources of clean energy. Rather than subsidizing fossil fuels, the government should provide incentives for companies to develop alternatives. Instead, politicians cast policies that favor short-term profits of energy companies, taking no account of the mounting costs of environmental damage.

Today’s leaders won’t pay for the tragic effects of a warming climate. If we pass the crucial point, history will judge harshly the scientists, reporters, special interests and politicians who failed to protect the planet. But our children will pay for the consequences.

It is not too late. The world has at most ten years to alter the trajectory of global greenhouse emissions. A good energy policy, economists agree, is not difficult. Fuel taxes should encourage conservation. With slow, continual increases of fuel cost, energy consumption will decline without harming the economy. Quality of life need not decline. However, the world needs politicians with courage to explain what is needed.
