Imagine waking up and finding the value of your assets has been halved. No, you’re not an investor in one of those hedge funds that failed completely. With the dollar slumping to a 26-year low against the pound, already-expensive London has become quite unaffordable. A coffee at Starbucks, just as unavoidable in England as it is in the United States, runs about ¥8.
The once all-powerful dollar isn’t doing a Titanic against just the pound. It is sitting at a record low against the euro and at a 30-year low against the Canadian dollar. Even the Argentine peso and Brazilian real are thriving against the dollar.
The weak dollar is a source of humiliation, for a nation’s self-esteem rests in part on the strength of its currency. It’s also a potential economic problem, since a declining dollar makes imported food more expensive and exerts upward pressure on interest rates. And yet there are substantial sectors of the vast U.S. economy from giant companies like Coca-Cola to mom-and-pop restaurant operators in Miami for which the weak dollar is most excellent news.
Many Europeans may view the U.S. as an arrogant superpower that has become hostile to foreigners. But nothing makes people think more warmly of the U.S. than a weak dollar. Through April, the total number of visitors from abroad was up 6.8 percent from last year. Should the trend continue, the number of tourists this year will finally top the 2000 peak? Many Europeans now apparently view the U.S. the way many Americans view Mexico as a cheap place to vacation, shop and party, all while ignoring the fact that the poorer locals can’t afford to join the merrymaking.
The money tourists spend helps decrease our chronic trade deficit. So do exports, which thanks in part to the weak dollar, soared 11 percent between May 2006 and May 2007. For first five months of 2007, the trade deficit actually fell 7 percent from 2006.
If you own shares in large American corporations, you’re a winner in the weak-dollar gamble. Last week Coca-Cola’s stick bubbled to a five-year high after it reported a fantastic quarter. Foreign sales accounted for 65 percent of Coke’s beverage business. Other American companies profiting from this trend include McDonald’s and IBM.
What are the climate scientists' attitudes towards the influence of climate change on the deserted areas?
What is the role of the sixth paragraph in the development of the topic?
The underlined sentence “… North Africa is the area of greatest disagreement among climate change modelers” in the last paragraph suggests that .
According to Martin Claussen, what is the main cause of the increased vegetation in deserted areas?
Desertification, drought, and despair-that's what global warming has in store for much of Africa. Or so we hear.
Emerging evidence is painting a very different scenario, one in which rising temperatures could benefit millions of Africans in the driest parts of the continent. Scientists are now seeing signals that the Sahara desert and surrounding regions are greening due to increasing rainfall. If sustained, these rains could revitalize drought-ravaged regions, reclaiming them for farming communities. This desert-shrinking trend is supported by climate models, which predict a return to conditions that turned the Sahara into a lush savanna some 12,000 years ago.
The green shoots of recovery are showing up on satellite images of regions including the Sahel, a semi-desert zone bordering the Sahara to the south that stretches some 2,400 miles.
Images taken between 1982 and 2002 revealed extensive regreening throughout the Sahel, according to a new study in the journal Biogeosciences. The study suggests huge increases in vegetation in areas including central Chad and western Sudan. The transition may be occurring because hotter air has more capacity to hold moisture, which in turn creates more rain, said Martin Claussen of the Max Planck Institute for Meteorology in Hamburg, Germany, who was not involved in the new study. "The water-holding capacity of the air is the main driving force," Claussen said.
While satellite images can't distinguish temporary plants like grasses that come and go with the rains, ground surveys suggest recent vegetation change is firmly rooted. In the eastern Sahara area of southwestern Egypt and northern Sudan, new trees—such as acacias—are flourishing, according to Stefan Kr?pelin, a climate scientist at the University of Cologne's Africa Research Unit in Germany.
"Before, there was not a single scorpion, not a single blade of grass," saidKr?pelin, who has studied the region for two decades."Now you have people grazing their camels in areas which may not have been used for hundreds or even thousands of years. You see birds, ostriches, gazelles coming back, even sorts of amphibians coming back," he said."The trend has continued for more than 20 years. It is indisputable."
In the author's opinion, the weak dollar leads to the following consequences EXCEPT that .
According to the last paragraph, what is the author’s advice to Americans?
How does the weak dollar affect the life of ordinary Americans?
How do many Europeans feel about the U.S with the devalued dollar?
