Attached photo from: http://www.ludopalaiseau.net/saint-remy-les-chevreuse-en-jeu/ Temperature differences in US cities ------------------------------------ {Up to x deg.F hotter than nearby rural, Average x deg.F hotter summer} Boston: {15.0, 1.3} NYC : {20.0, 2.7} LA: {27.0, 2.4} Detroit: {22.0, 2.8} These are stunning differences, from 7.5 degrees C (= 15 degrees F) to 13.5 degrees C (= 27 degrees F) Main UHI effects in Paris ------------------------- UHI causes are: Car emissions Central building heating/cooling installations Densely built area (mainly from concrete) UHI effects are: Higher city temperatures compared to urban surrounding Temperatures NOW (taken from online meteo stations) St.-Germain (Central Paris): 13.2 deg.C St.-Rémy-lès-Chevreuse (25km south of Paris): 10.9 deg.C Cf. http://www.meteo-paris.com/ile-de-france/stations-meteo.html Photos from: http://www.buci-hotel.com/blog/buci/en/category/saint-germain/ http://www.ludopalaiseau.net/saint-remy-les-chevreuse-en-jeu/ (Attached) Measures I would propose ------------------------ 1. Electric cars 2. Solar panels for buildings 3. Maybe restrictions to center circulation/traffic Policy making targeting the UHI effect -------------------------------------- Policies for electric cars are already in place: 1. Electric buses https://www.edf.fr/en/the-edf-group/world-s-largest-power-company/edf-official-partner-of-a-low-carbon-world/xxx/electric-buses-in-paris 2.
