The island nation of Tuvalu (图瓦卢) in the Pacific Ocean wants the bigger countries of the world to do
something about climate change. And it's not just for the good of the planet: Tuvalu could be covered by the
sea in less than 50 years if the planet gets much hotter.
Tuvalu has no industry, burns little petrol, and creates less carbon pollution than a small town in America.
However, this tiny place is on the front line of climate change. The increase in ocean temperatures and the
rising sea level -all resulted from a warming atmosphere-are making trouble for Tuvalu.
Sea level rise is the greatest problem. With an average elevation (高度) of 6 feet above sea level, Tuvalu
doesn't have far to go. Tuvalu's highest elevation is 4.6 meters-15 feet-but most of it is no more than a meter
above the sea. Several times each year the regular lunar cycle of tides (潮水), riding on the ever higher sea
level, brings the Pacific waters over onto roads and into neighborhoods. Sometimes a high tide can flood roads
and run across the whole land. You can never separate the sea from the land, so some natives warned visitors,
"You'd better not run after dark, for you may fall into the sea."
