CarletClimate risk in its neighbourhoods, streets and rivers, today and in 2050

We have scored the climate risk of the 4.548 buildings in Carlet using Cadastre data, satellite imagery and climate projections, and added it up by area, street and watercourse. The clearest change comes at night: from 33 to 69 tropical nights a year by 2050.

What stands out

What we found in Carlet

It comes from matching each building with its neighbourhood, its street, the nearest watercourse and its surroundings.

1

309 homes in a flood zone

309 homes

They are in the area that can flood once every 500 years according to the official maps (SNCZI); 1 of them are in the 100-year area.

According to the Ministry’s studies, this is an annual probability of 0,2 % (500 years) or 1 % (100 years), not “once every 500 years”: it can happen two years in a row. Small gullies are not always mapped.

2

From 33 to 69 tropical nights a year

33→69 nights

In a typical building in Carlet, nights when the temperature stays at or above 20 °C would rise from 33 a year (1991-2020) to about 69 by 2050. For this reason, 100 % of homes would be at a high or very high level.

Median of the buildings. Intermediate-to-high emissions scenario (SSP3-7.0).

3

Where there are fewer trees, 3,6 °C hotter

3,6 °C

Around homes with less than 2 % tree cover, the surface in summer is 0,6 °C above the median for Carlet; with more than 40 % tree cover, 3,0 °C below. 2.760 homes are in surroundings with almost no trees.

Ground surface temperature (Landsat), not air temperature. More trees usually go with less asphalt and lower density: this is a correlation, not a measure of the effect of planting trees.

4

409 homes at very high wildfire risk

1.166 buildings

These are 1.166 buildings right next to vegetation that can burn. Almost all are houses (1.166), on the edges of the town and in housing estates.

Proximity to woodland and to burnt areas (ESA WorldCover, EFFIS). It does not measure the state of the vegetation or any firebreaks.

55 in every 100 buildings were built before 1980

55 %

They were built before the first thermal insulation standard (1979). With 69 tropical nights a year by 2050, they will hold the most heat at night and have the most to gain from a retrofit.

What can be done

For the town council and for residents

For the town council and its technical staff

  • Climate shelters, and late-afternoon and evening opening hours at libraries and community centres in the areas with the most tropical nights.
  • Review with the river basin authority the watercourses with no official mapping that run next to homes, and keep them clear.
  • Firebreaks and evacuation routes in the streets that border woodland.
  • Download the tables by area, neighbourhood, street and watercourse (Data tab) to cross-check them with urban planning.

For residents

  • Air your home in the early hours, shade west-facing walls from the sun and ask about grants to insulate the roof.
  • If you live on a ground floor or have a garage next to a watercourse, have a plan: where to go upstairs, what to switch off and how to hear about warnings.
  • Keep the strip around your house clear of dry vegetation and know both ways out of your street.
  • Look up your building: the free report gives its level for each hazard, and the Climate Note gives the full detail.
