The impact of global warming could be twice as severe as the worst situation feared 【C1】__

____ the United Nations' scientists, the world's largest climate-mod- cling experiment has shown. Average temperatures could 【C2】______ by 11℃ to reach highs that would change the 【C3】______ of the globe, researchers who have run 60 000 computer simulations (模拟) of 【C4】______ change said yesterday.

The conclusions suggest that 【C5】______ by the UN's Intergovernmental Panel on Climate Change (IPCC) 【C6】______ be much too conservative. In the worst case, the world would 【C7】______ heat up by almost double the 【C8】______ increase imagined by the Panel. The IPCC's latest report predicted that temperatures will rise by 【C9】______ 1.4℃ and 5.8℃ by 2100.

A 【C10】______ 11℃ warmer than it is today would be unrecognizable: 【C11】______ records show that the 【C12】______ has been hotter than it is today for about 80 percent of its history, there is no evidence 【C13】______ it has ever been more than about 7℃ warmer.

Although it would take hundreds of years for the full 【C14】______ to be felt, the polar ice caps eventually would 【C15】______ completely, causing sea levels to rise by 70 m. to 100 m. Coastal and 【C16】______ cities such as London and New York would be submerged.

As the 11℃ 【C17】______ is a global average, temperatures would be expected to climb even 【C18】______ in some regions.

【C1】

第7题

On behalf of all the membership of the United Nations, I hereby reaffirm the role of thi

s international organization. When ti was created more than 60 years ago, the United Nations reflected humanity’s greatest hopes for a just and peaceful global community. It still embodies that dream. We remain the only world institution with the legitinacy and scope that derive from global membership, and a mandate that encompasses development, secutiry and human rights as well as the envoronment.

I restate that we are an organization without independent military capability, and we dispose of relatively modest resources in the economic realm. Yet our influence and impact on the world is far greater than many believe to be the case, and often more than we ourselves realize. This influence derives not from any exercise of power, but from the force of the values we represent. Among these values are the maintenance of the world order and the establishment of world harmony.

How will climate change affect global security？

Are governments doing enough to tackle climate change？

The British Foreign Secretary, Margaret Beckett, has warned that climate change will have implications more fundamental and serious for the security of nations than any single conflict in the future.

Speaking ahead of a UN Security Council debate on climate change, Margaret Beckett said the resources available to mankind were already stretched, and that an unstable climate threatened to make things worse.

In a world where the channels by which we interact and learn about one another are complet

ely transformed and in a world where actions have global impact, Expos are called to fulfill a new role, which is potentially more powerful than the one in the past. Today, to be effective platforms for education and progress, Expos must inspire and connect the actions of governments and civil society in their common effort to develop and implement sustainable solutions to the universal challenges we all face. Expos build bridges that connect different spheres of society. As such, they help promote ideas and initiatives with new policies, they foster the development of new forms of cooperation and, last but not least, they introduce a degree accountability for the actions of governmental institutions and civil society alike, as we are all called to contribute solutions to our common problems. This is why more recent Expos have elected the theme as their central core and organizing principle.

Questions are based on the following passage.

New Stanford research reveals that farmers in Europe will see crop yields affected as global temperatures rise， but that adaptation can help slow the decline for some crops.

For corn， the anticipated loss is roughly 10 percent， the research shows.

Farmers of these crops have already seen yield growth slow down since 1980 as temperatures have risen， though other policy and economic factors have also played a role.

"The results clearly showed that modest amounts of climate change can have a big impact on yields of several crops in Europe，" said Stanford doctoral student Frances Moore， who conducted the research with David Lobell， an associate professor of environmental Earth system science.

Moore described the results as somewhat surprising because Europe is fairly cool. "So you might think it would benefit from moderate amounts of warming，"she said. "Our next step was to actually measure the potential of European farmers to adapt to these impacts."

"By adaptation， we mean a range of options based on existing technologies，such as switching varieties of a crop， installing irrigation or growing a different crop， one better suited to wanner temperatures，" said Lobell. "These things have been talked about for a long time， but the novelty （新奇） of this study was using past data to quantify （量化） the actual potential of adaptation to reduce climate change impacts. We find that in some cases adaptation could substantially reduce impacts， but in other cases the potential may be very limited with current technologies."

Moore pointed out that the biggest issues are often how quickly farmers in Europe will adapt to climate change （adaptation uncertainty） and how crop yields will respond to climate change （response uncertainty）.

"This paper has shown that crops in Europe are sensitive to wanning and that adaptation can be important in reducing that impact，" Moore said. "The next question is how quickly farmers will use the available options for adapting.

Europe has already seen a lot of warming， so we should expect to already see adaptation if farmers are quick to respond to climate signals，"

What does the new Stanford research show？查看材料

A.People can do nothing about global wanning.

B.The influence of global temperature rise is increasing.

C.People can do something to slow the decline for some crops.

D.All crops" yields will decline as global temperatures rise.

The Effects of Global Warming on WeatherThere are hidden factors which scientists call “fe

The Effects of Global Warming on Weather

There are hidden factors which scientists call “feedback mechanisms”. No one knows quite how they will interact with the changing climate. Here’s one example: plants and animals adapt to climate change over centuries. At the current estimate of half a degree centigrade of warming per decade, vegetation (植物) may not keep up. Climatologist James Hansen predicts climate zones will shift toward the poles by 50 to 75 kilometres a year—faster than trees can naturally migrate. Species that find themselves in an unfamiliar environment will die. The 1000-kilometer-wide strip of forest running through Canada, the USSR and Scandinavia could be cut by half. Millions of dying trees would soon lead to massive forest fires, releasing tons of CO2 and further boosting global warming.

There are dozens of other possible “feedback mechanism”. Higher temperatures will fuel condensation and increase cloudiness, which may actually damp down global warming. Others, like the “albedo” effect, will do the opposite. The “albedo” effect is the amount of solar energy reflected by the earth’s surface. As northern ice and snow melts and the darker sea and land pokes (戳) through, more heat will be absorbed, adding to the global temperature increase.

Even if we were to magically stop all greenhouse-gas emissions tomorrow the impact on global climate would continue for decades. Delay will simply make the problem worse. The fact is that some of us are doing quite well the way things are. In developed world prosperity has been built on 150 years of cheap fossil fuels.

Material progress has been linked to energy consumption. Today 75 percent of all the world’s energy is consumed by a quarter of the world’s population. The average rich-world resident adds about 3.2 tons of CO2 yearly to the atmosphere, more than four times the level added by each Third World citizen. The US, with just seven per cent of the global population, is responsible for 22 per cent of global warming.

“Feedback mechanisms” in paragraph 1 most probably refer to______.

A．how plants and animals adapt to hidden factors

B．how plants and animals interact with the changing climate

C．how climate changes

D．how climate zones shift
