High Water Rising Levels
Global warming affects water levels by rising them. Theory says if the Polar Ice Caps coastal cities will flood and sink.
Antartic ice lost enough mass to raise global sea levels by 1.5 millimeters. A group of oceanographers announce June 2006 that sea level rose, on average 3 millimeters (0.1 inches) per year between 1993 and 2005.
the polar ice cap is near Green Land and northern
Miami, New Orleans and New York City completely under water it's a very real possibility if sea levels continue to rise. In Earth Under Water we'll see these events unfold as leading experts forecast how mankind will be impacted if global warming continues. They'll break down the science behind these predictions and explore ways humanity could adapt, including engineering vast dams near San Francisco, or building floating cities outside of New York.
These are examples of what can happen if sea level's begin to rise.
How we can cause sea level
Factory and burning fossil will cause our polar ice cap to melt.
melting ice can also affect coastal habitat and also make them go excitant for example Polar bears are having a hard time finding there homes because of the ice cap melting and other marine animals
