The Future We Don’t Want: how climate change could impact the world’s greatest cities

sheeja's picture

New research by Acclimatise, C40, the Urban Climate Change Research Network (UCCRN), and Global Covenant of Mayors for Climate & Energy reveals number of cities and citizens threatened by direct and indirect climate hazards if global greenhouse gas emissions continue unchecked. Bold climate action by cities is key to prevent 1.6 billion people being exposed to extreme heat, 800 million to coastal flooding, and 650 million to droughts. Billions of people in thousands of cities around the world will be at risk from climate-related heatwaves, drought, flooding, food shortages, blackouts and social inequality by mid-century without bold and urgent action to reduce greenhouse gas emissions. Fortunately, cities around the world are delivering bold climate solutions to avert these outcomes and create a healthier, safer, more equal and prosperous future for all urban citizens. This new research predicts how many urban residents will face potentially devastating heat waves, flooding and droughts by 2050 if global warming continues on its current trajectory. The Future We Don’t Want – How climate change could impact the world’s greatest cities also looks at indirect climate impacts and estimates how climate change under a ‘business-as-usual scenario’ will impact urban food security and energy systems as well as the urban poor, who are most vulnerable to climate change.
