Survey of 800 cities around the world finds almost 43% do not even have a plan to adapt to impacts of global heating. We need to do more. One in four cities around the world lack the money to protect themselves against the ravages of climate breakdown, even though more than 90% are facing serious risks, according to research. Cities are facing problems with flooding, overheating, water shortages, and damage to their infrastructure from extreme weather, which is growing more frequent as the climate changes. A survey of 800 cities, carried out by the Carbon Disclosure Project, found that last year about 43% of them, representing a combined population of 400 million people, did not have a plan to adapt to the climate crisis. Budgetary restraints were cited as the key reason by about 25% of cities. Many are reliant on national governments for the funding needed to protect their infrastructure and vulnerable populations from these threats. Installing renewable energy generation, such as solar panels, can generate a financial return, and energy efficiency projects begin to save money quite quickly. Businesses may provide another source of funding for some adaptation projects. Three-quarters of cities surveyed by CDP were already working with businesses on sustainability issues, or had plans to do so within the next two years.
