The climate situation is already worse in southern Africa than in most other regions. While the global average air temperature has risen by nearly 1°C since accurate weather records began a little over a century ago, in southern Africa temperatures have risen on average by twice this amount.
The IPCC report focuses on climate change and the impact on ecosystems. If we want to limit human-induced global warming to 1.5°C we probably can. The IPCC report identifies various routes by which emissions cuts would limit warming to 1.5°C; each makes assumptions about future changes in, for example, economic strategy, population growth and the rate at which low carbon energy is adopted.
