It rained a lot today. According to Environment Canada, Toronto's Pearson Airport saw 97.8 mm of rain fall before 2 PM. This is the fifth rainiest day on record; the record being July 8, 2013, which saw 126 mm fall. But today feels a lot like it did in July 2013. The same rivers, streets, and underpasses flooded. People needed rescuing. Cars got marooned. And more than 167,000 customers were left without power. I lost power in the Junction around lunchtime and it didn't come back on until just before 7 PM. That really hurt productivity, although I did manage to get in a workout during the outage.

Sadly, all of this is expected. The thing about air is that its ability to hold water depends on its temperature. For example, according to Nasa, a given volume of air at 20°C can hold 2x the amount of water vapor compared to air at 10°C. So as the earth's atmosphere warms, it is automatically going to hold more water vapor, and that means the potential for bigger and more severe storms.
