Predicted climate change and its impacts; alternative possible futures for local populations
Climate models predict hotter, drier conditions at desert margins. Depending on how much warming occurs, local communities face very different futures — from managed adaptation to forced migration.
Real World
The IPCC's RCP 8.5 scenario projects Sahel temperatures rising over 4°C by 2100, while community-led projects like the Great Green Wall aim to restore 100 million hectares of degraded land across Africa by 2030.
Exam Focus
Use named emissions scenarios (e.g. RCP 4.5 vs RCP 8.5) and contrast optimistic and pessimistic futures to show evaluation skills.
