evaporated the CO2 is absorbed into condensation and released as precipitation (or what we call acid rain). This is a form of pollution and is not helping the oceans in anyway. This is lowering the levels of pH in the ocean. pH plays a significant role in the oceans ecosystem‚ in the case of a rapid change in pH levels aquatic life can become stressed or die. Meaning aquatic life is unable to adjust to

Greenland are melting‚ thus causing the sea levels to rise. This past summer‚ in a disconcerting new scientific study by the climate scientist Michiel Schaeffer and his fellow colleagues‚ had suggested that no matter how quickly we cut this pollution‚ we are unlikely to keep the seas from climbing; subsequently‚ what is worse is that rising seas can raise the launching pad for a storm surge. Accelerated rates of erosion are another cause that attributes to the sea level rise. For erosion causes large economic
