Global Warming and Coastal Areas

                              Global Warming and Coastal Areas

Geographers and Environmentalists are expressing concern over the rate at which the polar ice caps in the northern and southern hemispheres are melting. Reports say, the increase in the rate was as a result of increase in solar radiation reaching the earth due to the deflation of the ozone layer.

The ozone is a gaseous layer composed of oxygen in a state of triple atomic fusion, which is designed to absorb ultra violate rays reaching the earth from the sun.

Scientists believe that, the ozone layer is being deflated by the increasing volume of carbon emissions into the atmosphere. The emission is blamed on high level industrialization and technological advancement in the use of automobiles and oil exploration and exploitation activities.

Scientifically, the ratio of water to soil on the earth surface is supposed to be 70% to 30%. But the increase in the rate at which polar ice caps melt due to the deflation of the ozone layer, which results in Global Warming, is threatening to alter this arrangement. And the end result is a rise in the volume of sea water and the eventual submergence of coastal settlements.

In Nigeria, the phenomenon is threatening to Submerge important coastal towns like Lagos, Port Harcourt and Yenogoa.
