Researchers used both aerial and satellite imagery, as well as machine learning, to map the carbon stock of every overstory tree in Rwanda—the first such inventory in the world.
Linking African Winds to Atlantic Storms
Simulations suggest that waves in the atmosphere above northern Africa influence the intensity, timing, and location of formation of Atlantic tropical cyclones.
Did a Chaotic Climate Drive Human Evolution?
A new 620,000-year climate record from East Africa reveals dramatic swings between wet and dry conditions that may have influenced human evolution.
Monitoring Moisture from Afar
Undisturbed tropical rain forests are experiencing more frequent droughts, but the ecosystems are isolated and difficult to assess. Scientists are using remote sensing to expand the depth and scope of monitoring efforts.
Food Deficits in Africa Will Grow in a Warmer World
Under the combined stress of growing populations and current warming trends, many African nations will face increasing shortfalls in food production in the coming decades.
Impact Crater off the African Coast May Be Linked to Chicxulub
The underwater crater, spotted serendipitously in commercial observations of seafloor sediments, is believed to have formed at roughly the same time as the famous Cretaceous-Paleogene impact event.
Proyecto de ciencia comunitaria ayuda a rastrear los riesgos geológicos en Uganda
Un proyecto comunitario en las tierras altas de Kigezi está ayudando a identificar puntos calientes de deslizamientos de tierra e inundaciones y cómo los peligros están evolucionando.
Tropical Wetlands Emit More Methane Than Previously Thought
Climate models could be vastly underestimating methane emissions from the world’s tropical wetlands, according to observational surveys of wetlands in Zambia.
River Floods Can Trigger Powerful Underwater Landslides
A record-length turbidity current triggered by river flooding has revealed a new link between the surface and the deep sea.
