How cities and extreme rainfall shape each other

New research brings together recent advances in urban hydrology, boundary-layer meteorology, extreme precipitation and flood-risk research and proposes a new framework for understanding how cities and extreme rainfall interact and co-evolve.

In Alaska, soil in permafrost regions is warming the fastest
