Global warming and natural events

The climate change which we are witnessing today is presumed to be due to the global warming caused by man-made activities and resulting emission of greenhouse gases (GHG) such as carbon dioxide. In fact, the main reason for the climate change may be due to global warming caused by other natural, earthly and solar events such as eruption of volcanoes, cyclic sun storms, etc. However, one can only try to minimize the contribution from man-made activities for global warming such as use of fossil fuels for electricity generation and for fueling transportation vehicles including aircrafts and space vehicles. It is difficult to believe that a fractional rise in the ambient and ocean temperature can cause the great meltdown of large Greenland and west Antarctica glaciers.

It is also possible that the actual gravity of the situation was not told to the world in time by the responsible organizations, or there are yet unknown natural reasons such as effect of variations in the geothermal energy for the climate change.

The responsible developed countries such as USA and the organizations such as United Nations should wake up to this reality of new climate cycle and upgrade the environmental monitoring systems and the computer models to reassess the scenario before major part of the globe gets submerged by the rising sea levels. Serious attempts also should be made to reduce the existing carbon dioxide and methane inventory in the atmosphere by use of appropriate technology.
