City-Scale, City-Relevant Climate Hazard Indicators Under 1.5°C, 2.0°C, and 3.0°C of Global Warming

The document introduces a data set providing 14 city-relevant climate hazard indicators for 996 large cities, based on NEX-GDDP-CMIP6 downscaled climate simulations. It compares a 1994-2014 historical baseline against three warming scenarios (1.5°C, 2.0°C, and 3.0°C) to assist city decision-makers in strategic planning and risk management. Key findings indicate that at 3.0°C of warming, cities will experience heatwaves that are 28% longer and 25% more frequent on average than at 1.5°C, alongside increased energy demand for cooling and higher transmission risks for arboviruses.

• Comparing the 3.0°C warming scenario to the 1.5°C scenario, cities will on average experience heatwaves that are 28% longer in duration and 25% more frequent per year.
• The data indicates that energy demand for cooling will increase for cities, and while the number of days with high malaria-transmission risk will see a modest decline, the annual number of days with high transmission risk for arboviruses will increase generally.
• The data set comprises 14 indicators—10 temperature-based and 4 precipitation-based—calculated at a 0.25-degree spatial resolution for 996 large cities, using the NEX-GDDP-CMIP6 family of downscaled climate simulations.
