Notes

Graph may not accurately represent tropical cyclone hazard levels in France’s overseas territories. Each country’s average surface temperature for 2000-2020 is taken from the Weather for Energy Tracker. If the slope of a linear regression of temperatures is higher than 0.042°C per year (+0.011°C from the world average), that country’s climate hazard level is “high”. If the slope is lower than 0.020°C per year (-0.011°C from the world average), the climate hazard is “low”. The world average is based on land temperature data from the NOAA National Centers for Environmental Information’s May 2021 Climate at a Glance: Global Time Series, accessed 1 June 2021. Flood, drought and tropical cyclone hazard levels were assessed against the following INFORM Risk Index indicators: “physical exposure to flood”, developed using historical riverine flood data from the United Nations Office for Disaster Risk Reduction (UNDRR); “drought probability and historical impact”, developed using historical data from the Food and Agriculture Organization (FAO), CRED and EM-DAT database; and “physical exposure to tropical cyclones”, developed using historical data from the UNDRR. The minimum value is 0 and the maximum is 10 (see the INFORM Risk Index page for indicator methodology details). In this report, risks are defined as: Low: 0-2.99; Medium: 3-6.99; and High: 7-10.
