Our climate is changing. The consequences of climate change will also be felt in Rotterdam. Rain showers are already becoming heavier, presenting the city with the challenge of excess water or flooding. In the long run, our low-lying delta city will also be confronted with rising sea levels and exceptionally high or low river levels and discharges. Furthermore, the temperature in the city will rise, and heat stress will affect increasing numbers of people. Longer periods of drought are also to be expected.
