How do you warn people downstream about fast-moving hazards that can change form and cross borders?
AI models could spot volcanic eruptions earlier – and new research says the lives saved make the occasional false alarm worth the price.
For many isiXhosa-speaking residents, disaster warnings arrive too late, or in language that is difficult to understand.
Scientists can warn of a risk of floods days in advance. But forecasts often aren’t definitive enough to trigger action.
For the first time, countries now have a shared way to understand whether the world is actually improving at adapting to climate impacts.
South Africa’s G20 presidency is a chance to lobby for investment in drought-tolerant crops, better irrigation, and early warning systems.
Where governance is weak and food supplies are unreliable, climate change causes child wasting and can be a warning sign of conflict to come.
The DRC illustrates how millions of people in fragile, violent and conflict-affected parts of the world are at risk of disaster.
Could South Africa’s flooding in 2022 have been foreseen? It has long been a challenge for scientists and engineers around the world.
To answer this question, it’s important to understand how PVMBG of the Ministry of Energy and Mineral Resources classify the physical events of Semeru and the corresponding alert level.
I helped forecast disaster – but nothing prepared for me what happened next.
Extreme heatwaves aren’t systematically monitored in most countries in sub-Saharan Africa. This leads to unnecessary and premature deaths which are often unrecorded.

While the Montecito, California mudslides took 20 lives, landslides kill far more people in developing countries. Tighter construction standards and early warning systems could help reduce their toll.
Early warning systems are available for things like tsunamis and diseases. Why not for animals as well?
The sea straddles two tectonic plates and is lined by large towns and cities. We need to take the tsunami threat seriously.
