You might think that "global warming" means nothing more than a rise in the world´s tempera-ture. But rising sea levels caused by it have resulted in the first evacuation ( 撤离 ) of an island na-tion-the citizens of Tuvalu will have to leave their homeland.
During the 20th century´, sea level rose $ -12 inches. As a result,Tuvalu has experienced low-land flooding of salt water which has polluted the country´s drinking water.
Paani Laupepa, a Tuvaluan government official, reported to the Earth Policy Institute that the nation suffered an unusually high number of fierce storms in the past ten years. Many scientists con-nect higher surface water temperatures resulting from global warming to greater and more damaging storms.
Laupepa expressed dissatisfaction with the United States for refusing to sign the Kyoto Protocol,an international agreement calling for industrialized nations to reduce their greenhouse gas emis-sioins, which are a main cause of global warming. "By refusing to sign the agreement, the US has effeetivly taken away the freedom of future generations of Tuvaluans to live where their forefathers have lived for thousands of years," Laupepa told the BBC.
Tuvalu has asked Australia and New Zealand to allow the gradual move of its people to both countries.
Tuvalu is not the only country that is vulnerable (易受影响的 )to rising sea levels. Manmoon Gayoon, president of the Maldives, told the United Nations that global warming has made his country of 311,000 an "endangered nation".

Thomas Alva Edison was awarded more patents( 专利 )on inventions than any other American.
When he died in 1931, Americans wondered how they could best show their respect for him. One suggestion was that the nation observe a minute or two of total black-out. All electric power would be shut off in homes, streets and factories.
Perhaps this suggestion made Americans realize fully what Edison and his inventions meant to them. Electric power was too important to the country. Shutting it off for even a short time would have led to complete confusion. A black-out was out of the question.
On the day of Edison´s funeral, many people silently dimmed their lights. In this way they honored the man who had done more than anyone else to put the great force of electricity at his countrymen´s fingertips.
