Answer:
There are many green house gases and carbondioxide is one of them. Green house gas has the ability to stop the heat from going to the atmosphere. This heat energy reduces the atmospheric carbondioxide to dissolve in the ocean water so more concentration of carbondioxide is present in the atmosphere which stop the reflected sunlight rays into the space and thus increase the temperature of the earth surface. This increase in temperature called global warming.
