Scientists: Rising Sea Levels to Continue 科学家称海平面将继续上升 Scientists say sea levels are rising and will continue to do so into the future. Coastal communitiesaround the world are already experiencing the impact of rising seas. Many cities and towns aretaking steps to deal with this new reality. Photographers have taken pictures to document those efforts. Their photos are part of an exhibitcalled "Sink or Swim: Designing for a Sea Change." It can be seen at the Aquarium of the Pacific, inLong Beach, California. There, experts explain the causes of the rising seas and how people aretrying to adapt to the changes. Disastrous storms and floods could be a new reality around the world. That is the opinion ofoceanographer Jerry Schubel. He is president of the Aquarium of the Pacific. “Global climate change is resulting in rising seas, coastal flooding and increasingly powerful stormsurges.” A video produced by the aquarium shows how water levels are rising. It also shows how low-lyingplaces that flood historically are the areas most vulnerable to the sea level change. Dan Cayanstudies weather conditions for the Scripps Institution of Oceanography at the University ofCalifornia, 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 willaccelerate in the next several decades.” Scientists estimate that, by the end of the century, sea levels around the world could rise by morethan a meter and could continue to rise. Mr. Cayan says heat-trapping greenhouse gasses arecausing temperatures to rise. ”Sea level rise will not end in 2100. It’s an ongoing problem, as the planet adjusts 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 North and South Poles tomelt. “And as the climate warms, the potential for unleashing stored water on Earth, largely inGreenland, 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 exploreshow people are affected by flooding and how they are adapting to the rising water levels. “We have the issue of the rising seas but that is coupled with our desire to live on coast lines.There is an intense level of development on coastlines.” One picture in the exhibit shows students attending a floating school on a wooden boat. JonasBendiksen took the picture in Bangladesh. A photo from the Netherlands, taken by Iwan Baan,shows a more high-tech floating building: a modern houseboat made of aluminum and glass. Scientists say city planners in coastal communities must continue to come up with new ways toadapt to rising seas. They say this can be done through futuristic buildings, roads and otherinfrastructure. They say all these structures need to withstand damaging fierce storms and limithuman suffering.
