Upon hearing that the planet had warmed by one degree Celsius, a conservative politician said that he could get on a plane in Melbourne and get off in Sydney an hour later and find the temperature higher by a comfortable six degrees, so what’s the problem?

In fact, a global rise of one degree has increased the incidence of extremely hot days in southeast Australia by a factor of ten.

Similarly, my recent regime – the probiotics, the supplements, the gym routine, the three symptomatic treatments I was on – was feeling like a bedrock of stability. Not a cure, but a rich, strong foundation from which stars sometimes shine, from which crystals can grow.

Until the day the ambulance arrived.
