There is high confidence that climate change and projected socioeconomic development would increase exposure in inundation areas , resulting in a large increase in direct flood damages as several times more in all warming levels . Alfieri et al.  estimated a 120 and 400% increase in population affected by river flooding for 2°C and 4°C warming, respectively, and a 170% increase in damage for 2°C warming without socioeconomic impact development .
