The idea in one paragraph
The Earth is wrapped in a layer of gases that holds some of the sun’s heat, like a blanket. That is a good thing: without it the planet would be freezing. But when we burn coal, oil and gas, and clear forests, we add more of these heat-trapping gases to the air. The blanket gets thicker, and the planet warms.
What is changing
- Higher temperatures. The world has warmed by more than one degree Celsius since the late 1800s, and each decade has been warmer than the last. Hot days become hotter and more frequent.
- Changing rain. Warmer air holds more moisture. In many places this means heavier downpours and longer dry spells, which are harder for farmers and city drainage systems to cope with.
- Rising seas. Water expands as it warms, and ice melts. For coastal cities, even a small rise increases the risk of flooding and erosion.
What it means closer to home
For West Africa, these changes show up in familiar ways: uncertain planting seasons, flooded streets after a heavy storm, hotter nights, and pressure on water supplies and coastlines. People who have the least to spare are often hit hardest, which is why practical preparation matters.
Two kinds of response
Mitigation means reducing the heat-trapping gases we add: cleaner energy, efficient buildings, protecting forests.
Adaptation means preparing for the changes already under way: better drainage, cooler buildings, flood-ready planning, drought-resistant farming.
Both are needed. Buildings and cities sit at the centre of both, because they use so much energy and because they decide how safe people are when extreme weather arrives.
What an ordinary person can do
- Make your home cooler and more efficient, using shade, ventilation and efficient lighting.
- Keep drains and gutters clear, and avoid building across water paths.
- Plant and protect trees.
- Choose clean energy where it is affordable, such as solar for lighting or water heating.
- Share what you learn. Neighbours who understand the risks make better decisions together.
Staying informed
For reliable weather and climate information, look to your national meteorological agency and international bodies such as the World Meteorological Organization and the Intergovernmental Panel on Climate Change. We will keep sharing simple explanations and practical ideas on this website and in our short videos.
