In the spirit of accelerating climate action, the upcoming UN Climate Ambition Summit holds the promise of a brighter, more sustainable future for our planet. As world leaders gather at the UN General Assembly, it is increasingly clear that cities will be at the forefront of efforts to protect our planet and build the new, green economy.
In a world threatened by climate upheaval, where the scars of devastating wildfires, lethal heat waves and catastrophic floods are etched into our collective memory, leaders around the globe have a responsibility to act. Last summer, London saw 40-degree heat that created the busiest week for the London Fire Brigade since the Blitz. This year, record-breaking heat waves and smoke from Canadian wildfires caused air-pollution levels five times higher than average in Boston and across North America.
