finding was reported by Nkemelang et al. (2018), who analyzed the expected changes in precipitation and temperature in Botswana, at increasing global temperatures of 1ºC, 1.5ºC, and 2ºC. Findings showed that at 2ºC, the country would experience longer periods of warmer day temperatures, colder nights, and increased precipitation levels. Pendergrass and Hartmann (2014) also reported that rainfall responded to global warming in two ways: an increase in both the total amount of rainfall received and the total rates of heavy rainfall. Therefore, more precipitation would not only be expected, and at a higher frequency. An explanation for the occurrences as reported by Trenberth (2011) posited that with the increase in global temperature, higher heating would lead to greater evaporation rates. At the same time, warming the air by 1ºC enhanced the water-holding capacity of the air by about 7%, thereby, leading to higher moisture and intense precipitation. On the contrary, however, the researcher argued that higher air temperatures led to increased surface drying and drought durations.
