analyze potential impacts of oceans on human populations as the result of climate change in the current century.

The result of climate change is ocean levels increasing because of the increase in temperature. Ice is melting due to climate change and this is causing the ocean levels to rise rapidly.

Water sources may also be contaminated, making the water unsafe for humans to consume.
