Is climate change making floods worse?

The latest reports from the Intergovernmental Panel on Climate Change (IPCC) have presented increasingly confident scientific evidence that climate change is caused by humans and is making extreme weather events like floods more frequent, intense, and unpredictable. The number of people affected by floods has increased, and is projected to keep increasing, alongside global warming during the 21st century.

The number of extreme climate-related disasters has doubled since the early 1990s. In 2018 Climate related disasters accounted for more than 80 percent of all major internationally reported disasters.

This increasingly strong evidence shows the importance of investing in flood resilience in order for people to be able to thrive despite the changing climate. 

In March 2022 the Zurich Flood Resilience Alliance brought together IPCC authors and flood resilience practitioners to interpret climate change science and share experiences from working with people in flood prone communities at the frontlines of climate change. 

Who is affected by climate change?

Climate change does not affect us all equally. Instead climate change exacerbates vulnerabilities that already exist, for example due to poverty, displacement, or conflict.

Research by the World Bank (carried out before the impacts of the Coronavirus pandemic) shows that without sufficient climate change adaptation, the inequality gap will widen and the impacts of climate change could push more than 100 million people below the poverty line by 2030.

Developing countries will bear an estimated 75-80 percent of the costs of climate change.

By 2050, over 200 million people worldwide will experience humanitarian need resulting from the combination of climate-related disasters (including floods) and the socioeconomic impacts of climate change.

We must recognise that climate change is already having humanitarian impacts and invest in adaptation in vulnerable and crisis affected communities.

We must also accept that many people and communities are beyond successful adaptation, they might already have lost their homes and livelihoods as a result of floods and other climate change impacts and should be compensated for the loss and damage they have experienced.
