Temperature parameters analysed
Study Area
Conclusions
Harrison et al. (2011)
Daily minimum and maximum
temperature
Mozambique
Increases in average mean temperature
Increases in, both minimum and
maximum temperature
At Tete station, a decrease in average
maximum and 90th percentile daytime
temperatures
Collins (2011)
Annual mean minimum
Annual mean maximum
Diurnal temperature range
Africa
Significant increasing temperature trends
were found in Southern Hemisphere of
Africa among other regions
For the months June–August, South
Africa saw significantly warmer
temperatures in the period 1995–2010
than in the period 1979–94
When the two most recent decades are
compared with the period 1979–90,
warming is observed and is concentrated
in the most recent decade, from 2001 to
2010
Over the period 1979–2010, there is a
significant (to 1% level) upward linear
trend noted with an estimate of 0.16
0C/decade
Morishima and Akasaka (2010)
Annual mean minimum
Annual mean maximum
Diurnal temperature range
Southern Africa
Annual mean surface temperature has
shown an increasing trend across the
whole region with particularly large rates
of increase in Namibia and Angola
Surface temperature from Namibia to
south-eastern South Africa tending to
increase from July to October
