Climate change is emerging as a global challenge, transcending geographical boundaries and affecting every corner of our planet. It is already having a considerable impact on people and ecosystems. In this section dedicated to the environment, we focus on Climate change and its consequences for floods, as well as on the populations vulnerable to the Risk of flooding.
Floods, as hydrological events of sometimes devastating proportions, are a crucial facet of the direct consequences of Climate change. They are the result of a wide range of factors, from extreme precipitation and snowmelt to storms and rising sea levels. These phenomena have a significant impact on ecosystems, material assets and human life.
At the same time, our exploration extends to the fundamental question of Climate justice, an essential dimension in understanding the dynamics induced by Climate change. The impact of Climate change is not limited to environmental changes, but transcends social and economic barriers and reinforces existing inequalities. By studying the links between Climate change, flooding and Climate justice, we aim to decipher the mechanisms linking these complex dynamics.

Figure TS.7 VULNERABILITY | (a) The global map of Vulnerability is based on two comprehensive global indicator systems, namely INFORM Risk Index and WorldRiskIndex (2019). Climate change hazards and exposure levels are not included in this figure. The relative level of average national Vulnerability is shown by the colours. Vulnerability values are based on the average of the two indices, classified into 5 classes using the quantile method. A hexagon binning method was used to simplify the global map and enlarge small states. The map combines information about the level of Vulnerability (independent of the population size) with two classes of population density (high density ≥ 20 people/km2 and low density < 20 people/km2 ). The selected examples of local vulnerable populations underscore that there are also highly vulnerable populations in countries with overall low relative Vulnerability {8.3.2, Figure 8.6}
