global warming causes average temperature of the world to change, or we sometime call extreme weather. The weather around the world change from the same pattern, such as summer is longer and hotter, and winter is shorter and colder. Second, The rise of sea level which cause ice melting at the north pole and south pole due to the higher of temperature. The ice melt down also affect the sea temperature which kill some marine life.
