Doctors on Climate Change Consequences

The climate crisis will determine the lifelong health of today’s children and elderly, doctors have warned, noting that global heating was already causing harm. The report is produced by 120 experts from 35 institutions, including the World Health Organisation, World Bank, and Yale and Tsinghua universities.

Children are especially vulnerable and the global team of researchers say rising temperatures mean the bacteria causing deadly diarrhoea will thrive while poorer crop yields could lead to more malnutrition.

The annual Lancet Countdown on Health and Climate Change tracks the impacts of global heating on health. As well as children, older people are particularly vulnerable to heatwaves since they are less able to regulate their temperature and fluid balance.

The authors found that 220 million more people over 65 were exposed to heatwaves in 2018 compared with 2000. Europe, the report said, was especially at risk, due to its high number of older citizens living in large, hot, cities.
 It was found that, spurred on by global heating, the ability of dengue fever to be transmitted by mosquitoes in 2017 was at the second highest level recorded since 1950, while nine of the 10 most suitable years for transmission had happened since 2000. “Dengue is the most rapidly expanding infection around the world,” said Nick Watts, executive director of the Lancet Countdown. “It is called breakbone fever because it is incredibly painful.”
The report also found 2018 was the second most suitable year on record for the spread of the cholera bacteria, which cause much of the diarrhoeal disease and wound infections around the globe. Watts said the first native cases of tick-borne encephalitis in the UK were recorded in October. “This is a disease we know is moving as a result of climate change.”
Elizabeth Robinson, a co-author and professor at the University of Reading, stated, Coal-fired power plants should be phased out worldwide and travel shifted to public transport while urgent action was needed to cut agricultural emissions by humans eating seasonal plant-based diets. The report found the greenhouse gas emissions from livestock in the UK were equivalent to 40% of emissions from the power sector. Robinson said the technology existed to tackle climate change and that action.  The choices today were “entirely political”, she said.

Stella Hartinger, of Cayetano Heredia University, in Peru, and a Lancet Countdown author, said: “The path that the world chooses today will irreversibly mark our children’s futures. We must listen to the millions of young people who have led the wave of school strikes for urgent action.”
