Adaptation to frightening new normal and reducing emissions further and faster is critical, scientists warn Dozens of people drowned, hundreds had to be rescued and thousands were displaced when floods struck the coasts of west Africa last month. Now scientists have concluded that the rains that caused the floods were supercharged by climate breakdown. Global heating, they say, turned what should have been a routine weather event into a climate catastrophe. They also warn that the countries affected must adapt to a frightening new reality. “The climate is changing faster than most nations can adapt,” said Friederike Otto, a professor of climate science at Imperial College London. “Adapting to these now common events is critical, but so is reducing emissions much further and faster, to allow us time to keep up with the changes we’ve already put into motion. Quite simply, until emissions stop these extremes will only grow worse.” Residents on the Gulf of Guinea coast expect rain this time of year. Rainy season runs from May until the end of July. Granted, this year it had been particularly heavy, but what began on 20 June caught people by surprise. Over the course of 72 hours, intense rainfall drenched the densely populated coastal regions of Côte d’Ivoire, Ghana, Togo and Nigeria. More than 140mm of rain fell in some cities in less than a day. The deluge overwhelmed drainage systems, triggering a series of flash floods. From Lagos to Monrovia in Liberia, the overflow inundated neighbourhoods and washed away markets. It submerged roads and swamped infrastructure. At least 34 people died in Ghana. Five died in Togo. In Côte d’Ivoire, 59 have died as a result of floods since May.
