                               Global  warming  or  global  warming  is  an  event  that  causes  the

                        average temperature of the earth to increase, both from the oceans, land and
                        atmosphere.  According  to  the  Natural  Resources  Defense  Council

                        (NRDC), global warming is the process of increasing air temperature due
                        to  the  trapping  of  heat  in  the  atmosphere  by  carbon  dioxide  gas  which

                        causes climate change and causes various disasters on earth. According to

                        the National Wildlife Federation, global warming or global warming is
                        an  increase  in  air  temperature  on  the  earth's  surface  which  can  cause

                        various natural disasters such as earthquakes, floods, storms, droughts, and
                        others.  In  addition  to  natural  disasters,  universally  global  warming  also

                        causes  changes  in  the  landscape  of  life  on  the  earth's  surface  and  kills
                        various types of species on earth. Other consequences of global warming are

                        the impact of agricultural products, the loss of glaciers, and the extinction

                        of  various  types  of  animals.  Some  of  the  things  that  scientists  still  have
                        doubts about are the amount of warming that is expected to occur in the

                        future, and how that warming and changes that occur will vary from region
                        to region.
