Effect of global warming on monsoon:With reference to Chhattisgarh State

Abstract

Global warming is increasing the average temperatures of the earth. A rise in earth’s temperatures can in turn root to other alternation of ecology including sea level and modifying the quantities and patterns of rain fall. This modification may boost the occurrence and concentration of severe climate events such as floods famines, heat waves tornados and twisters. Scientists all over the world are making prediction about the ill effect of global warming and connecting some of the events that have taken place in the Past few decades as an alarm of global warming. The Intergovernmental panel on climate change (IPCC) conclusion that increasing greenhouse gases concentration resulting from human activities such as fossils fuel burning and deforestation are responsible for most of the observed temperature increase since the middle of 20th century. As of June 2012, only the United State historically the world’s largest emitter of green house gases which is main cause of global warming has refused to rectify the KYOTO protocol treaty. In Chhattisgarh state gradual decrease in rain fall has been seen since last 50 years due to global warming. During the last 5 decades the average rainfall in Chhattisgarh state has fallen down from 1301 millimeter to 1150 millimeter .In Chhattisgarh state the arrival of monsoon every year has been noted the 2nd week of June and this year monsoon arrived on 5th June, 2012, this monsoon word is derived from Arabic word mousim. Recently the scientists have prepared a Visual ALTAS to know where the rain falls have occurred. This visual atlas has been prepared by international team led by National University of Australia.
