Global warming is increasing the frequency and ferocity of some extreme-weather events, highlighting the need for governments at all levels to reduce vulnerabilities and increase the resilience of their citizens to such events.

The spectrum of tools available to help is familiar: improved forecasts and warnings for severe weather, rigorously enforced zoning and building codes, and restoration of ecosystems that serve as buffers between people and river floods or coastal-storm surges, for instance.
