VOA慢速英语:科学家称海平面将继续上涨

Scientists say sea levels are rising and will continue to do so into the future. Coastal communities around the world are already experiencing the impact of rising seas. Many cities and towns are taking steps to deal with this new reality.

Photographers have taken pictures to document those efforts. Their photos are part of an exhibit called "Sink or Swim: Designing for a Sea Change." It can be seen at the Aquarium of the Pacific, in Long Beach, California. There, experts explain the causes of the rising seas and how people are trying to adapt to the changes.

Disastrous storms and floods could be a new reality around the world. That is the opinion of ocean ographer Jerry Schubel. He is president of the Aquarium of the Pacific.

“Global climate change is resulting in rising seas, coastal flooding and increasingly powerful storm surges.”

A video produced by the aquarium shows how water levels are rising. It also shows how low-lying places that flood historically are the areas most vulnerable to the sea level change. Dan Cayan studies weather conditions for the Scripps Institution of Oceanography at the University of California, San Diego. He says sea levels are rising at a higher rate now than a few years ago.

“In the last couple of decades it’s risen at a greater rate. And, we think very confidently that it will accelerate in the next several decades.”

Scientists estimate that, by the end of the century, sea levels around the world could rise by more than a meter and could continue to rise. Mr. Cayansays heat-trapping greenhouse gasses are causing temperatures to rise.

”Sea level rise will not end in 2100. It’s an ongoing problem, as the planetad justs to a new, essentially a new energy balance because of greenhouse gases.”

He adds that this pollution is warming the planet, and causing ice at the Northand South Poles to melt.

“And as the climate warms, the potential for unleashing stored water on Earth,largely in Greenl and, Antarctica, holds a lot of potential sea level rise in the future."

Frances Anderton serves as guest curator of the Sink or Swim exhibit. She says the show explores how people are affected by flooding and how they areadapting to the rising water levels.

“We have the issue of the rising seas but that is coupled with our desire to liveon coast lines. There is an intense level of development on coast lines.”

One picture in the exhibit shows students attending a floating school on a wooden boat. Jonas Bendiksen took the picture in Bangladesh. A photo from the Netherlands, taken by Iwan Baan, shows a more high-tech floating building: a modern house boat made of aluminum and glass.

Scientists say city planners in coastal communities must continue to come upwith new ways to adapt to rising seas. They say this can be done through futuristic buildings, roads and other infrastructure. They say all these structures need to with stand damaging fierce storms and limit human suffering.
