Tuvalu, a tiny country in the Pacific
Ocean, has asked for help as it fears it will be flooded by the sea water.
Storms and huge waves are a constant threat
and none of Tuvalu’s nine little islands is more than five meters above sea
level. Salt water is already entering the country’s drinking water supply, as
well as damaging plantations that produce fruit and vegetables. Without urgent
help, the country’s days are numbered.
But Tuvalu is not the first place to face
sinking into the sea. Venice, a historic city in Italy, best known for its
canals, has sunk 24cm over the past 100 years. Experts say that it will have
sunk another 20-50cm by 2050. A century ago, St. Mark’s Square, the lowest
point in the city, flooded about nine times a year. Nowadays, it happens more
than 100 times.
While Venice is slowly sinking into the mud
on which it stands, Tuvalu’s rising sea level is caused by global warming.
The average global temperature has
increased by almost 0.5 centigrade degree over the past century, scientists
expect it to rise by an extra 1-3 degrees over the next 100 years.
Warmer weather makes glaciers(冰川) melt, adding more water to
the ocean. The warmer temperatures also make water expand, so it takes more
space, causing the sea level to rise. The sea level has risen about 10-25cm in
the last 100 years.
The main cause of global warming is human
pollution. Through burning coal and gas, people have been increasing the
greenhouse gases in the atmosphere. This adds to the power of the greenhouse
effect, making the planet even warmer.
Many scientists believe that, if the
warming is not stopped, there would be huge climate changes. The sea level
could rise by one meter this century.
Should this come true, millions of homes
would be flooded by the sea water and the world would be flooded with climate
refugees(難民)
looking for somewhere to live.
