Have you ever imagined that the place you live is going to disappear at someday? Have you cared about the place that you live? You spent your whole childhood or whole life in your hometown but it’s going to disappear. Don’t doubt that these things will not happen around you, it’s happening in everywhere now. The cities are close to the ocean are starting loss their urban area because of climate change. Global warming effects the seal level. According to the National Ocean Service, “The two major causes of global sea level rise are thermal expansion caused by warming of the ocean (since water expands as it warms) and increased melting of land-based ice, such as glaciers and ice sheets”. The global sea level has rose over the past century and has increased in the recent decades. According to the National Ocean Service, “in 2014, global sea level was 2.6 inches above the 1993 average- the highest annual average in the satellite record”.
In figure 1, we can tell sea levels in the U.S. are rising faster along the east coast and the Gulf of Mexico. In those areas, the global average sea level has increased 8 inches since 1880. However, some of the city sea level rising are more than 8 inches, in this figure, we can easily tell the sea level of Los Angeles, San Francisco, Seattle, San Diego, Pensacola, Key West, Boston, Charleston, New York City, and Washington are below than 8 inches. But the sea level of Atlantic, Norfolk, and Galveston are higher than 8 inches. This means that the rise in sea level in those areas are higher than 8 inches cities are more dangerous for people to live.
As this figure 2 shows if the sea level is rising about 7.5 ft every year. Maybe ten more years after 2100 the whole city will be flooded. For example, Venice is a world-class wonder. A city built on more than 100 small islands, connected by a maze of bridges and canals. According to an article by The Local, “the Mediterranean is set to rise by between 90 cm and 140 cm before 2100, flooding Venice and several other at-risk areas”. Venice could disappear within 100 years because global sea level rise may sink the Italian city.
