According to the Climate Institute, one of the worst impacts resulting from the influence of human beings on climate change is the global sea level rise, caused by the melting of the arctic ice. There is statistical evidence that the sea level rise has increased in the last two or three decades. A recent study, published by a team of scientists, found that in the last 20 years the sea level has risen 3 inches globally.

Coastal cities are vulnerable to the sea level rise because of the risks and impacts this phenomenon can bring. With the current rate average of 1/8 inch rise every year, the sea level will rise up to 6.6 feet by the year 2100. This means, a lot of coastal cities will be under water.
I always hear that coastal cities will be underwater in 2100, New York will be on of them, which means that we will be living in underwater unless we move to other place, and there is no exception.
thanks for your comment Keng Wai. Sea level rise is pretty scary
