You might think that “global warming” means
nothing more than a rise in the world’s temperature But rising sea levels
caused by it have resulted in the first evacuation(撤离)of
an island nation-the citizens of Tuvalu will have to leave their homeland.
During the 20th century ,sea level rose 8-12
inches. As a result .Tuvalu has experienced lowland 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 connect higher surface
water temperatures resulting from global warming to greater and more damaging torms.
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 emissions(导致温室效应的气体排放),which
are a main cause of global warming . “By refusing to sign the agreement ,the US has
effectively 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 .Maumoon Gayoon, president of the Maldives,
told the United Nations that global warming has made his country of 311,000 an
“endangered nation”.
