The world is falling short of promises made under the UNFCCC climate deal to mitigate and adapt to the increasingly devastating impacts of climate change. Meanwhile, challenges of rising sea levels, urban heat, freshwater shortages, floods, droughts and more extreme weather events are becoming more severe and frequent. As cities increase in number and size, it underscores the need to strengthen resilience capabilities to withstand climate-related shocks and stresses and to build resilience for net-zero allowing to accelerate adaptation action in a carbon-constrained world.
