The whole idea of normal and the basis on which 1:500 and 1:1,000 events are built is starting to feel well past expiry date. We've had no end of them in the 21st century, whether cat 5 hurricanes, flood, fire or as in this case summers. It's not normal now, it's before we broke it, and normal is starting to sound and feel archaic.<p>After 5 in 15 years, and on course for a sixth, the benchmark looks way off. At what point should it simply become a 1:3 year summer, or just "summer"?<p>How deniers can experience it and keep acting like nothing's happening beats me.
