the rest of the country, and by 2018 approached a 2 °C average increase compared to the industrial revolution with an accelerating increase in the past few decades. Temperature records The hottest year in France on record was in 2020 with an average temperature of 14.0 °C which beat the last record of 13.9 °C in 2018. The all-time hottest day was recorded on the 28th of June 2019, a day that saw a lot of new records during the 2019 European heat wave. With the hottest place being in Gallargues-le-Monteux in Southern France with a staggering 45.9 °C. Due to an increase in global average temperature France has been hit by several extreme heat waves over the past few years, this is because of hot air passing over Europe from North Africa. Heat waves With a decrease in summer precipitation and a global increase of average temperature, heat wave events like the 2018 European heat wave and the 2019 European heat wave set new summer temperature records and are only expected to get more intense and common due to climate change. Sea-level rise With an increase in glacier and polar ice cap melting, sea level rise is expected to increase, affecting both the Atlantic and the Mediterranean coasts. Future climate projections predict that sea levels around France will increase by at least 1 meter by the year 2100. Low coasts will be in danger of erosion and being permanently submerged, heavily threatening coastal infrastructure, new coasts will be under threat from temporal flooding, an estimated 140,000 homes and 80,000 people are located in the zone that is at risk for permanent submersion by 2100. Glaciers An increase in mean annual temperature causes glacial retreat. In the European Alps it is estimated that around half of glacial ice had disappeared between 1850 and 1975. Another 30–40% from what remained was estimated to have disappeared between the time period 1980–2005. According to future climate models, what remains of the glaciers in the Alps as of the year 2100 compared to 2017, could be nothing more than one-third in a best case scenario regardless if the global carbon emission hits zero. If these emissions continue to rise those glaciers will be gone by 2100. At the Mont Blanc altitudes between 1500 and 2500 meters saw a total of 25 more snow-free days when comparing the years 1964–75 and 2005–2015. An increasing temperature
