Abstract
The effect of climate variability is unprecedented, affecting an array of
ecosystems globally. Intensified effects of rainfall and temperature
variations are affecting urbanised ecosystems where urban sprawl has
ramified. This study looks at modelled retrospective climate variability
changes in the Roysambu area, an urbanised suburb in Nairobi County,
Kenya. The study aimed to ascertain the changes in rainfall and
temperature in the past 30 years. From the simple regression analysis, the
total annual average rainfall has slightly increased in the area (y = 0.5235x
+ 72.037, R2 = 0.0618). There were changes in temperature where the
maximum average temperature had increased by 0.5 °C with a simple
regression model (y = 0.012x + 0.6281, R2 = 0.0814). From the findings,
climate variability has been experienced in the area through simple
regression model retrospective analysis over time.
