An increase in sea levels of just 18 to 59 centimeters would make the Maldives—a nation of tiny coral islands in the Indian Ocean—virtually uninhabitable by 2100, the UN’s climate change panel has warned.

President Mohamed Nasheed has vowed a fight for survival, and last month he signed a deal with a Dutch company to study proposals for a floating structure that could support a conference centre, homes and an 18-hole golf course.

“It is still early stages and we are awaiting a report on the practicality,” a government official who declined to be named said.

The company, Dutch Docklands, is currently building floating developments in the Netherlands and Dubai. There was no immediate comment from the firm but its website said it undertook projects that make “land from water by providing large-scale floating constructions to create similar conditions as on land”.

The Maldives began to work on an artificial island known as the Hulhumale near the crowded capital island of Male in 1997 and more than 30,000 people have been settled there to ease congestion. The city, which has a population of 100,000, is already protected from rising sea levels by a 30-million-dollar sea wall, and the government is considering increasingly imaginative ways to combat climate change.

Nasheed, who staged the world’s first underwater cabinet meeting in October to highlight his people’s serious and difficult situation, has even spoken of buying land elsewhere in the world to enable Maldivians to relocate if their homes are completed covered.

He has also promised to turn his nation into a model for the rest of the world by - 2 -

阅读下列四篇短文,从每小题后所给的A,B,C或D四个选项中,选出最佳选项。 Rivers may be a significant source of the greenhouse gas nitrous oxide (一氧化二氮), scientists now find.

Their calculation suggests that across the globe the waterways contribute three times the amount of nitrous oxide to the atmosphere as had been estimated by the International Panel on Climate Change (IPCC), the United Nations scientific body charged with reviewing climate change research. They found that the amount of nitrous - 3 -

oxide produced in streams is related to human activities that release nitrogen (氮) into the environment, such as fertilizer use and sewage discharges.

“Human activities, including fossil fuel combustion and intensive agriculture, have increased the availability of nitrogen in the environment,” said Jake Beaulieu of the University of Notre Dame and the U.S. Environmental Protection Agency in Cincinnati, Ohio, and lead author of the paper published this week in the journal Proceedings of the National Academy of Sciences.

“Much of this nitrogen is transported into river and stream networks,” Beaulieu said. There, microbes (微生物) convert the nitrogen into nitrous oxide (also called laughing gas) and an inert gas called dinitrogen (二氮).

The finding is important, the researchers say, because nitrous oxide is a powerful greenhouse gas that contributes to climate change and destruction of the stratosphere’s ozone layer, which protects us from the sun’s harmful ultraviolet (紫外线) radiation. Compared with carbon dioxide, nitrous oxide is 300-fold more powerful in terms of its warming potential, though carbon dioxide is a far more common greenhouse gas. Scientists estimate nitrous oxide accounts for about 6 percent of human-induced climate change.
