Human-caused climate change worsened recent torrential rains and floods that devastated parts of southern Africa, killing more than 100 people and displacing hundreds of thousands, researchers said yesterday. The study was conducted by scientists from across the world using peer-reviewed methods to assess the impact of climate change on severe weather patterns and events. Pinto, who co-authored the study, said the climate models used struggled to pinpoint exactly how much worse the recent floods were made by climate change, but that a 40% increase in the intensity of the rains would be impossible to explain without human-caused climate change. Around 1.3 million people across southern Africa were affected by this month’s floods, The World Health Organization said. Researchers seek Africa-focused modelsThe researchers also have called for the development of climate models in Africa in order to best understand the dynamics and extent of the impact of climate change in the continent’s various regions.
