Science has provided us with clear, overwhelming evidence of man-made climate change, it provides an impartial response to those who cling to doubts. Global warming and climate change are terms for the observed century-scale rise in the average temperature of the Earth’s climate system and its related effects (Gillis, Justin 28 November 2015). Multiple lines of scientific evidence show that the climate system is warming (Hartmann, D. L.; Klein Tank, A. M. G.; Rusticucci, M.2013). (Borenstein, Seth, 2015). Science is widely acknowledged that “climate change is a far greater threat to the world than international terrorism”, (Sir David King, the UK Government’s chief scientific adviser, 2004). This widely acknowledged statement places the climate change problem squarely in the realm of global security and thus a concern for all. Since then, both science and lived experience have shown that without immediate action, flooding, drought, hunger and debilitating diseases such as malaria and cholera will severely impact upon millions of people around the world and nowhere more so than in Southern Africa. Climate change is the increasing rise in temperature which has been estimated to be about 0.1 degree Celsius per decade for the next two decades, even if greenhouse gas (GHG) and aerosol concentrations are kept at year 2000 levels. Climate change is resulting to extreme events that include floods and draughts (climate variability), which are becoming increasingly frequent and sever. Certain regions of Africa are more prone to such extreme events than others. It is generally caused by excessive emission and accumulation of “greenhouse gases (principally carbon dioxide) in the atmosphere.
