Abstract
The IPCC’s Fifth Assessment Report offers the following key messages for Africa:
Africa’s climate is already changing and the impacts are already being felt
The Fifth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC) finds, beyond reasonable doubt, that the Earth’s climate is warming. Since the 1950s, the rate of global warming has been unprecedented compared to previous decades and millennia. The IPCC finds with 95% certainty that human activity, by increasing concentrations of greenhouse gases in the atmosphere, has been the dominant cause of the observed warming since the mid-20th century.
The Fifth Assessment Report presents strong evidence that warming over land across Africa has increased over the last 50–100 years. Surface temperatures have already increased by 0.5–2°C over the past hundred years. Data from 1950 onwards suggests that climate change has changed the magnitude and frequency of some extreme weather events in Africa already. The health, livelihoods and food security of people in Africa have been affected by climate change.
