Climate change and the risk to civilisation: the doctors’ prescription

Climate change and the risk to civilisation: the doctors’ prescriptionCanberra Times , By Colin Butler, 21 December 2018 The 2018 State of the Climate report, released yesterday, again highlights the risk to human wellbeing from our love affair with fossil fuels. Coal, oil and gas have underpinned the incredible advances in affluence, population size, and health since development of the steam engine. But fossil fuel use has an optimum dose, which is now well past.

We are metaphorically drowning in carbon dioxide, the invisible, odourless waste product of burning fossil fuel. As the report notes, this is increasing heatwaves, acidifying the oceans and raising the sea level. It is also lowering the micronutrient concentrations of food.

The report cites growing effects on human and animal health, including from increased fires and flooding, and says extreme heat days are rising alarmingly. This month, dozens of Australians were rescued from the Hume Highway, stranded by intense rainfall. Record heat and fire ravaged north Queensland. A third of the spectacled flying fox population died from heat, possibly exposing animal rescuers to viral diseases.

In November, San Francisco air was worse than Delhi, due to fires that ruined the Californian city of Paradise, recently home for 30,000 people.

Earlier this month, at the Katowice conference, held in the heartland of Polish coal seams, David Attenborough called climate change the greatest threat to humanity in thousands of years. He warned that, without action, “the collapse of our civilisations, and the extinction of much of the natural world, is on the horizon”.

Attenborough’s warnings have a distinguished pedigree. In 2010, Frank Fenner, the great Australian scientist who helped eradicate smallpox, warned that humans risked total extinction due to overpopulation, resource over-consumption, environmental destruction and climate change. Martin Rees, a past president of the world’s oldest scientific organisation, the Royal Society, has warned this century might be our last. ……

The physical climate is changing, so fast that more and more people, including many children, can now recognise it. If we can harness the internet, new technology, and the common sense of ordinary people then we will we at least have a reasonable chance. Recognising the validity of these warnings is a vital step if we are to survive.
