Europe was this week hit by an extreme heatwave exacerbating drought conditions and sparking wildfires in France, Spain, Italy, Greece and Portugal. The UK also broke its record temperature exceeding 40C. All this just weeks after flooding caused widespread disruption in Sydney, Australia. Scientists agree that reducing greenhouse gas emissions is key to limiting the severity of climate change. But the planet has already warmed by 1.1C above pre-industrial levels and temperatures are expected to continue rising. More than half of the world’s population live in cities and that figure is expected to rise to 68% by 2050. Extreme heat, droughts, wildfires, storm surges and flooding - both inland and along coastlines - will increasingly cause damage and deaths. So, how can we make cities more resilient to the inevitable impacts of a warming planet? What obstacles are preventing greater action? And will the rich world protect itself while poorer communities are left to fend for themselves?
