[font size=3]The UK-based Centre for Ecology & Hydrology (CEH) has led an international team of scientists who reveal global warming is responsible for a tripling in the frequency of extreme West African Sahel storms observed in just the last 35 years.
Professor Christopher Taylor, a Meteorologist at CEH, and researchers from partner institutions including Université Grenoble Alpes in France, also suggest that climate change will see the Sahel experience many more instances of extreme rain in future.
Professor Taylor and the fellow scientists’ findings – published in the journal Nature – note that further strengthening of intense storms in the Sahel known as Mesoscale Convective Systems (MCSs) will increase the risk of more frequent and severe flooding and disease due to poor sanitation in West African cities. The findings are also being presented this week at the General Assembly of the European Geosciences Union at its meeting in Vienna, Austria.
…
The research indicates that MCS intensification is linked to increasingly hot conditions in the Sahara desert resulting from man-made greenhouse gas emissions. Saharan warming affects storm intensity across the Sahel, a band of semi-arid land to the south of the desert which is home to some of the most vulnerable populations on the planet.
