UN bodies and health authorities are being advised to prepare for a world temperature rise of 4°C because scientists no longer believe that politicians are capable of holding the temperature rise below the internationally agreed limit, 2°C above pre-industrial levels.

She said the Australian Government was ignoring climate change and still expecting places like Darwin to expand. But that was unlikely because they would soon become untenable. “If employers ask people to continue to work in temperatures above 37°C, they will be killing them in increasing numbers,” she said.

Dr Hanna said humans were well suited to living in cool conditions and felt comfortable in temperatures between 20°C and 23°C because their muscles produced heat from within.

But in parts of Arizona, Australia and India temperatures were reaching – and for days staying above – the thermal maximum of endurance, which was around 37°C, the core heat of the human body. Above that temperature, and sometimes below, depending on the combination of heat, humidity and air speed, keeping cool put too much strain on the heart and people began to die.

She said that she was studying how human societies could survive such daytime temperatures and continue to work. “There could be some night working, or people could work, rest in cool rooms, and then work again, but their productivity would drop and it would be economically unviable to have factories or farms in such conditions.”
