In the area you have selected (France) extreme heat hazard is classified as medium based on modeled heat information currently available to this tool. This means that there is more than a 25% chance that at least one period of prolonged exposure to extreme heat, resulting in heat stress, will occur in the next five years. Project planning decisions, project design, and construction methods should take into account the level of extreme hazard. The following is a list of recommendations that could be followed in different phases of the project to help reduce the risk to your project. Please note that these recommendations are generic and not project-specific.

According to the most recent assessment report of the Intergovernmental panel on Climate Change (IPCC, 2013), continued emissions of greenhouse gases will cause further warming, and it is virtually certain that there will be more frequent hot temperature extremes over most land areas during the next fifty years. Warming will not be regionally uniform. In the area you have selected, the temperature increase in the next fifty years will be slightly lower than the worldwide average, but still significant. It would be prudent to design projects in this area to be robust to global warming in the long-term.


  • VULNERABILITY ASSESSMENT: The high-level information available in ThinkHazard! indicates the presence of extreme heat hazard in your project area. Before committing significant resources to this issue, you should further evaluate if your project is vulnerable to extreme heat and whether a more detailed assessment and/or intervention should be considered. More information
  • SEEK INFORMATION: Obtain pre-existing extreme heat hazard information. ThinkHazard! predominantly uses global datasets, therefore for more detailed project planning you should determine the availability of pre-existing local extreme heat hazard information to check whether your project is indeed located in regions prone to extreme heat. In this respect, it should be noted that large built-up areas such as cities or harbors are more likely to experience excess heat than rural areas, because of the urban heat island phenomenon.

  • PROFESSIONAL GUIDANCE: Consultation with engineering and climate impact assessment professionals will provide a more detailed understanding of the risk posed to your asset by extreme heat. The level of guidance required will depend upon the level of hazard present, the vulnerability of the asset and local legislation that might apply. More information
  • MONITORING AND FORECASTING: Identify extreme heat monitoring and forecasting systems. These are designed to provide communities with advanced warning of extreme heat based largely on information contained in weather forecasts, complemented with temperature monitoring. They can be used to trigger protocols (e.g., the deployment of heat-health action and emergency response plans) to mitigate against the effects of extreme heat. More information
  • INTERDEPENDENCY: Consider vulnerability of other assets within the project's dependency network: If your project is interdependent with other projects, it is important to assess the vulnerability of the entire network if the service provided is critical. More information
  • HEAT MANAGEMENT: Your project or development should consider heat management measures appropriate to your sector of operation, for example, technological adaptation, building design, or changing working practices. More information
  • AVOID INCREASING HAZARD: Built infrastructure may alter heat hazard. Constructing a significant piece of infrastructure can significantly alter the thermal properties of the area, generally inducing higher temperatures. Any newly built infrastructure covering large enough areas (e.g., new city quarter or harbor zone) should be undertaken with consideration as to how this will influence the local microclimate.
