We cooked on Friday. In between the deluges. Walking to the office across the breezeway at Darling Harbour – except there was no breeze – I overheard a young women say to her friend, ”It’s supposed to be 29 but it feels like 40.” She was right, the forecast was wrong. It hit 38 degrees in the Sydney CBD. Even that figure is misleading. On the streets it was worse – oppressive, debilitating.
One year ago, the City of Sydney council, keenly aware we are cooking ourselves in our cities, commissioned a thermal-image map of the CBD. The mapping flight took place in the early morning of February 6 last year. The maximum temperature that day was 29 degrees and the minimum 22 degrees. The thermal map, however, showed something else.
