Cyclone Freddy wreaks havoc in Malawi and Mozambique.

Cyclone Freddy, which hit Mozambique and Malawi, highlights the importance of early warning systems and addressing the issue of unplanned shanty towns in the face of global warming and population growth. Mozambique's structured warning system saved lives, while Malawi's inconsistent warnings left many unprepared. Climate change is making tropical storms stronger, and rapid urbanization is creating vulnerable cities. Deforestation and weak building materials exacerbate the impact of storms.
