Devastating rains that triggered floods in Cameroon, Chad, Niger, Nigeria and Sudan in recent months – killing hundreds of people and displacing millions – were worsened by human-caused climate change, a team of international scientists announced Wednesday.
Global warming made the seasonal downpours this year about 5-20 percent more intense across the Niger and Lake Chad basins, said World Weather Attribution (WWA), a group of scientists studying the link between climate change and extreme weather.
