CLIMATE VARIABILITY IN PAST AND ITS EFFECTS

If we look at the past evidences, it is found out that over the past century a lot of climate variability or the climate change has occurred due to volcanic eruptions, fluctuation in the solar energy, and other natural variations. Then, since 1970s there is rampant increase in the green house gases because of human activities. The record shows that 1990 has been warm in terms of global average temperature. 1998 was the warmest year and more specifically; first eight months of 1998 were the warmest of those months on the record.

If human does not control the activities that may lead to global warming and the concentration of carbon dioxide increases by twice its value, then most probably, the temperature of the earth increases by 2.5 ºC. It may seem to be less, but it is actually the annual increase in temperature of earth. This 2.5ºC rise represents about half an ‘ice-age’ in terms of climate change and it is obviously the rapid change.
