Statistical analyses of climate change (case study of rivers east Senatorial District of Rivers State Nigeria)

Abstract

The formation of settlement mainly depends on the climatic conditions of that location, Variation in temperature has been a challenge to scientist because of its direct and indirect effect on meteorological phenomena. The temperature trends globally revealed a continuous variability that is seasonally dependent within any particular year considered. Data's for Rivers east Senatorial district were taken for a period of 5 years (2008–2013) and evaluated for possibility of climate change. Including the concentration of carbon dioxide over the senatorial district around the same time as temperature was assessed from Nigeria metrological center. The highest minimum temperature of 17.9oc was recorded in okrika in 2009. The highest maximum temperature mean temperature of 42.1oc was recorded in port Harcourt in 2012. The mean minimum and maximum temperature showed a reducing and increasing temperature respectively, occasioned by natural and manmade activities such as gas flaring, bush burning, illegal refining of crude oil and other activities.the concentration of carbon dioxide over the Rivers East Senatorial district has been one of the contributing factor of rising temperatures in the senatorial district. This investigation examination the inconstancy of temperature (day by day, month to month and annual).the study uncovered expanding occasions of extraordinary temperature in wide territories in the senatorial region aside from in Ogu/Bolu of and Okrika nearby government zones of the area. In coming down season, expanding temperature of the atmosphere state and debilitating temperature limits are seen in Port Harcourt. All in all, expanding temperature of the atmosphere and upgrading temperature limits were normally watched Obio/Akpor, Port Harcourt and Ikwerre Nearby Government Territories.
