Global warming is expected to increase tropical cyclone impacts - but the timing of that warming makes a big difference to the impacts when you also account for population growth, according to international research. The study found that 2°C of warming by around 2050, combined with a middle-of-the-road growth scenario, would mean an extra 52 million people are exposed to tropical cyclones. A stronger mitigation scenario reaching 2°C around 2100 limits this increase to 25 million. The authors say rapid climate action would avoid peak temperatures and peak global population growth happening at the same time which would limit climate-change-driven exposure. The authors say cumulatively, over 1.8 billion people could be saved by 2100.
