Abstract: Abstract Climate change presents one of the most significant global challenges of the twenty-first century, with Africa being disproportionately affected despite contributing minimally to global greenhouse gas emissions. This chapter provides an in-depth review of the evidence on the magnitude, patterns, and implications of climate change across the African continent. It explores historical trends revealing a consistent rise in average temperatures—approximately 0.5 °C per decade—over the last century, with projections indicating that Africa will experience warming at a rate faster than the global average. The review identifies major regional climate impacts, including increased heatwaves, variability in rainy seasons, prolonged droughts, intensified flooding, and rising sea levels, each posing serious risks to agriculture, water security, human health, and infrastructure. The literature further highlights significant sub-regional variations: North Africa faces acute water scarcity, East Africa contends with flooding and disease outbreaks, West and Central Africa experience erratic rainfall and declining agricultural productivity, while Southern Africa is marked as a climate hotspot with severe warming and drying trends. These climate patterns are exacerbating food insecurity, undermining water resource management, threatening biodiversity, and increasing the spread of vector-borne diseases. Building on these findings, the chapter proposes a set of actionable recommendations and policy implications. These include the promotion of climate-resilient agriculture through the development and dissemination of drought- and heat-tolerant crop varieties; investment in sustainable water infrastructure and watershed management; scaling up early warning systems and disaster preparedness; and strengthening national and regional climate governance frameworks.
