Climate change warning: brace for hotter heat waves, stronger storms

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.  That's according to a new report from the United Nations-backed Intergovernmental Panel on Climate Change (IPCC).  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.
