The study looked at how floods in Norway might change in the future due to climate change. They used computer models to simulate floods in different areas and found that most places with rain-driven or mixed rain and snow floods will likely see bigger floods. The models showed that the biggest floods could increase by up to 99%. The way they estimated flood sizes played a big role in the predictions, with some methods showing larger increases in extreme floods than others. Overall, the study found that flood estimates could vary a lot depending on the method used, and that floods are likely to get worse in many parts of Norway.
