PARIS—Climate change will damage the health of an entire generation unless there are immediate cuts to fossil fuel emissions, from a rise in deadly infectious diseases to surging malnutrition, experts warned on Thursday.
Children across the world were already suffering the ill effects of air pollution and extreme weather events, said The Lancet Countdown in its annual report on the impact of climate change on human health.
And far worse is to come for future generations, it warned: airborne diseases, malnutrition due to mass crop failures, and even mental and physical trauma from increased flash flooding and wildfires.
The Lancet Countdown is a coalition of 35 institutions, including the World Health Organization and the World Bank.
Their warning comes as some of Australia’s worst wildfires in living memory continue to burn across its eastern seaboard, and after a global youth strike inspired by Swedish schoolgirl Greta Thunberg.
August was the hottest month ever recorded and Earth has already warmed 1 degree Celsius since industrialization.
The Paris Climate treaty of 2015 enjoins nations to limit temperature rises to 2 C, or preferably to 1.5 C if possible.
Yet emissions continue to rise year on year, putting Earth on a path that could lead to a 4 C temperature rise by the end of the century—bringing peril for human health.
The report said “nothing short” of a 7.4-percent year-on-year cut in carbon dioxide emissions until 2050 would limit global warming to 1.5 C.
“A kid born today has an average global life expectancy of 71 years so that brings them to 2090. That means that kid will experience a 4 C world,” Nick Watts, executive director of The Lancet Countdown, told Agence France-Presse (AFP).
The report, compiled by 120 experts, used the latest available data and climate modeling to predict global health trends as the mercury climbs throughout the decades.
In parts of the world already, the health effects from climate change start in the first weeks of a baby’s life.
In the last 30 years, the global yield potential of staple crops, such as maize, winter wheat and rice, have all declined, putting infants and small children at heightened risk of malnutrition.
Infant malnutrition impacts every stage of a child’s life, stunting growth, weakening the immune system and throwing up long-term developmental problems.
More children will also be susceptible to infectious disease outbreaks.
In just three decades, the number of days worldwide of prime infectiousness for the Vibrio bacteria—which causes much of child diarrheal disease worldwide—has doubled.
This not only increases the likelihood of children contracting diseases, such as cholera in at-risk regions, it also enlarges their spread.
The report found that mosquito-borne diseases, such as dengue and malaria, were also on the rise, putting half of the world’s current population at risk.
Frequent economic disruption
And people in cities are already suffering premature disease and death from air pollution—coal plants alone contributed a likely one million premature deaths worldwide in 2016.
Extreme weather events are likely to proliferate as temperatures climb, posing increasingly frequent economic disruption.
For example, in 2018, 45 billion hours of work were lost due to extreme heat globally compared with 2000.
“Climate change is not about 2100, climate change is about Wednesday, November 13, 2019,” said Watts, speaking on the day.
One of greatest threats
“Populations around the world are migrating, growing and aging in the areas that are worst affected by climate change.”
He said even lawmakers in developed, temperate nations “ought to be already extremely concerned” about heat waves; temperature records were smashed across Europe this year in a string of deadly heat waves.
The study found that last year an additional 220 million over-65s were exposed to extreme heat, compared with the historical average.
Reacting to the report, The Lancet’s editor in chief Richard Horton said climate change was “one of the greatest threats to the health of humanity today.”
“But the world has yet to see a response from governments,” he added. “We can’t afford this level of disengagement.”—AFP
