Think of climate change, and the mind instantly tends to go to melting ice caps, arid plains, forest fires and sinking tropical islands. But the impact of rising temperatures will not only be felt in the hinterlands. A report, commissioned by London’s mayor, this week highlighted the possibility of “more intense and frequent heatwaves, more intense rainfall, flash flooding and sea level rise” in the British capital. It is a reminder that cities across the world — where over 80 per cent of global gross domestic product and the majority of the planet’s population live — are also under significant threat.
