Businesses are counting the likely cost of ‘heatflation’

When the doors opened in the morning on July 24 at Tokyo’s 10th annual Heat Solution expo, the temperature outside was nudging 35 deg C and

heatstroke warnings were in place for much of Japan.

Weather apps, compounding the sense of nature in extremis, cautioned that a tornado would shortly hit the capital.

The deadliness of disarray is everywhere, and so, the expo powerfully suggests, is the threat of ever greater economic division around the cost of keeping cool.
