Abstract: Climate change has the tendency of negatively affecting the socioeconomic development of a society at both community and national level. The change climate which is manifested as the temporal variability in the climatic elements, varies spatially with location. In this work, attempt is made to analyse the magnitude and direction of the changes of the various climatic elements of greater Yola, Adamawa State Nigeria over a three decade time series. The works involves linear regression analysis of the temporal variability of the mean annual minimum, maximum and meanannual temperatures, mean annual rainfall, mean annual sunshine, mean annual humidity and the mean annual evaporation. The results indicate positive trends for all the variables except for the sunshine and evaporation data which showed negative trends. The model regression equations derived were tested at 0.05 level of significance and the results showed that a p-value of 0.201 (>0.05) for annual mean maximum temperature, 0.000 (<0.05) mean annual minimum temperature, 0.000 (>0.05) for the mean annual maximum temperature, 0.672 (>0.05) mean annual rainfall, 0.7768 (> 0,.5) for the mean annual sunshine hours, 0.129 (>0.05) for the mean annual relative humidity and 0.263 (>0.05) for the mean annual evaporation. Hence, only the mean annual minimum and maximum temperatures are predictable using their respective model equations. The work however showed evidence of local eratic and irregular climate variability relative to global warming.
