Briefings

A new study led by Ph.D. student Raz Nussbaum and Dr. Moshe Armon, supervised by Efrat Morin at Hebrew University of Jerusalem, indicates that climate change may cause cities to face more severe flooding despite reduced rainfall. The research suggests that while total precipitation might decrease, the intensity and frequency of extreme urban floods are increasing due to changing atmospheric patterns.

Key points

• The study was conducted by Raz Nussbaum, a Ph.D. student, alongside Dr. Moshe Armon and Professor Efrat Morin from the Hebrew University of Jerusalem.
• The research indicates that even as overall rainfall decreases, extreme urban flooding events are becoming more severe and frequent due to climate change.

Context

This research addresses a critical urban planning challenge where reduced rainfall does not necessarily mean safer cities, as extreme events may intensify under changing climate conditions.

Limitations

The study is a preprint and does not include full results or conclusions. The evidence is limited to the initial findings of the study, and the specific mechanisms driving the increase in extreme events are not fully explained.
