Climate Change

Climate Change is regarded  as one of the fastest growing  challenge of the 21st century, though ,there may be  uncertainties around its  scale, scope and pace but  one thing ,at least ,is clear that cities and towns are utterly  exposed to significant impacts of Climate Change .


The city Gorakhpur and its neighborhood  had always experienced a pleasant climate ,however, in the last few years ,there has been observed rapid and unexpected changes in the climate along  with a speedy population growth which ,in turn, this has deteriorated the environment of the city. The average maximum temperature of the city is 25.68oC which goes up to31.95o C in the summer and the minimum temperature measured  is above 19.57 o C.


In the past decade, the city has experienced major ups and downs in temperature and rainfall.  There has been a continuous changes in the annual maximum and minimum temperature of the city since the year 2003.  Approximately 9.51 % increase in the maximum temperature during 2003-2004 has been observed in the city ,whereas,  the annual minimum temperature reflected a decreasing trend like  in the year  2002, it was 19.63o C which came down to   15.98oC. Thus, 22.84 percent decrease in the minimum temperature from the year  2002 to 2008 has been noted. This way ,tremendous fluctuations  in   temperature of summer and winter has been observed. These fluctuations are  not ,necessarily, due to the outcome of CO2 induced anthropogenic Climate Change, but  due to changes in  patterns of Climate Change that are affecting ,adversely, the lives of people . People have started experiencing these changes on  their daily lives and adapting it  their unique manner.


The  annual average rainfall of the city is  119.2 cms. The analysis of the existing trend of rainfall indicates that the quantity  of rainfall has increased ,though, the number of days of rainfall has  reduced drastically. From the observation of past data of rainfall  and different models of prediction , it can be   deduced that there is likely to be  high uncertainty in the  rainfall pattern in the near future. It is projected that in each season, the rainfall might either increase or decrease e.g.   in the months of December, January and February ,the precipitation is likely to decrease while   increase in the months of March, April, May, October and November.


From the analyses of different climatic models such as CGCM3, CNRM, CSIRO, and MIUB, it has been predicted that the  maximum temperature is expected to  increase in all four seasons and  the fluctuations in  temperature will be most prominent   in both winter and summer seasons. But  for  determining rainfall pattern in the month of monsoon ,there are  not enough models in  agreement from which such conclusion can be derived . The  fluctuation in temperature and its  impact on precipitation affects  ,tremendously, local agriculture and urban water management of Gorakhpur City  . The increased temperature will also affect  the pattern of occurrence  of water and vector borne diseases.
