In his address on this year’s World Cities Day, UN-Secretary General António Guterres recognised that “cities have borne the brunt of the pandemic” and called upon governments to “prepare cities for future disease outbreaks”. Authorities cannot waste this opportunity to build back better by simultaneously addressing the increasing economic hardship for the urban poor and climate change impacts. This will help prevent not only future health risks but also the increased risk of urban violence and insecurity.

The momentum for climate action we are witnessing is extraordinary. Throughout 2019, millions of people took the streets all around the world to join the youth climate movement's school strike. Yet at this year’s most important climate politics meeting, the UN Climate Action Summit in New York, most governments were far from committing to sufficient action to avert dangerous climate change. Dr. Beatrice Mosello and Dr. Virginie Le Masson explain how to move things forward.
