Climate change quintuples likelihood of extreme West Africa rainfall

Climate change has made extreme rainfall in West Africa five times more likely than in the late 19th century, scientists said Thursday. The finding follows regional floods that killed nearly 100 people last month.

The Study

A rapid attribution study by the World Weather Attribution network found that climate change increased the likelihood of extreme rainfall in West Africa by a factor of five compared to pre-industrial levels. The analysis focused on the Sahel region, where floods in August killed at least 97 people in Niger, Nigeria, and Chad. Scientists used climate models to compare current conditions with a counterfactual world without human-caused warming.

Regional Impact

The floods displaced over 200,000 people across the three countries, according to the UN Office for the Coordination of Humanitarian Affairs. In Niger alone, 53 deaths were reported, while Nigeria recorded 28 fatalities. The extreme rainfall also damaged infrastructure, including roads and bridges, hampering relief efforts.

What's Next

Governments in the region are expected to review early warning systems ahead of the next rainy season. It remains unclear whether international climate finance will be mobilized to support adaptation measures.

Alpine 100-year floods to occur every 45-80 years by 2100, study projects

A new study projects that 100-year floods in the Alps will occur every 45 to 80 years by the end of the century due to intensified heavy precipitation from global warming. Researchers from the WSL Institute for Snow and Avalanche Research SLF used hourly data from 384 rivers to model the change. The findings, published in Science Advances, are significantly bleaker than earlier estimates.

Climate attribution science strengthens legal cases against oil majors

A new generation of attribution science is making it easier to link extreme weather events to climate change, potentially bolstering lawsuits against fossil fuel companies. The research allows plaintiffs to quantify the role of emissions in specific disasters, shifting legal debates from causation to damages. Even as courts have dismissed some cases for lack of direct causality, the evolving science is narrowing that gap.

European heatwave may have caused 12,000 excess deaths in week

A heatwave in Western Europe in late June may have caused over 12,000 excess deaths, according to AFP calculations based on official statistics. The peak temperatures from June 22-28 affected seven countries including France, Germany, and Spain.

Desert dust in Europe rises as aridity drives North African emissions

A new study published in Nature on July 15 establishes a database of daily dust metals in Europe, showing that transported dust intrusion events over the past decade are linked to changes in atmospheric circulation. An ice core analysis reveals that the increase in dust since pre-industrial times is governed by increasing aridity in North Africa. The trend has implications for health and solar energy installations, even as particulate pollution from human activity declines across the continent.
