California's critical energy and transportation infrastructure faces significant climate related
risks over the course of the century, including more frequent and intense wildfires, prolonged drought, and accelerated sea - level rise.
Not surprisingly, the media feeding frenzy has resulted, anecdotal evidence suggests, in a sharp drop in youth football registrations for this fall's season, with parents fearful that playing football will almost inevitably expose their kid to an unreasonable
risk of injury (which,
of course, is patently untrue; more than 7 million kids in the U.S. currently play football, very few
of whom, statistically speaking and despite a few well - publicized cases - are likely to end up committing suicide because
of the hits they sustained playing the sport, and millions upon countless millions who have played football
over the past
century without apparent ill effect).

risk assessments generally assume that bridges may collapse when a 100 - year flood — a streamflow with 1 percent probability
of being exceeded in any given year, or 63 percent
over the
course of a
century — occurs.
