Topic: More ’Korean bananas’ to be harvested this year amid climate change
Jeju Island was long considered the only warm-enough region in Korea for commercial banana farming, but climate change is now turning the mainland into a producer of the tropical fruit.
According to the agricultural technology center in North Chungcheong Province, the number of people investing in banana farming has surged in recent years.
About 99.7 percent of all bananas consumed here are imported, mainly from the Philippines, and most of the rest is produced on Jeju. But with more farmers exploring the field, this soon could change.
Topic: Climate change exposes future generations to life-long health harm
A child born today faces multiple and life-long health harms from climate change, growing up in a warmer world with risks of food shortages, infectious diseases, floods and extreme heat, a major global study has found.
Climate change is already harming people’s health by increasing the number of extreme weather events and exacerbating air pollution, according to the study published in The Lancet medical journal. And if nothing is done to mitigate it, its impacts could burden an entire generation with disease and illness throughout their lives.
“Children are particularly vulnerable to the health risks of a changing climate. Their bodies and immune systems are still developing, leaving them more susceptible to disease and environmental pollutants,” said Nick Watts, who co-led the Lancet Countdown on Health and Climate Change study. He warned that health damage in early childhood is “persistent and pervasive,” and carries lifelong consequences. “Without immediate action from all countries to cut greenhouse gas emissions, gains in wellbeing and life expectancy will be compromised, and climate change will come to define the health of an entire generation,” he told a London briefing.
Yet introducing policies to limit emissions and cap global warming would see a different outcome, the research teams said. In that scenario, a child born today, would see an end to coal use in Britain, for example, by their sixth birthday, and the world reaching net-zero emissions by the time they were 31.
The Lancet study is a collaboration by 120 experts from 35 institutions including the WHO, the World Bank, University College London and China’s Tsinghua University.
On a “business-as-usual” pathway, with little action to limit climate change, it found that amid rising temperatures and extreme weather events, children would be vulnerable to malnutrition and rising food prices, and the most likely to suffer from warmer waters and climates accelerating the spread of infectious diseases such as dengue fever and cholera.
Among the most immediate and long-lasting health threats from climate change is air pollution, the researchers said. They called for urgent action to reduce outdoor and indoor pollution through the introduction of cleaner fuels and vehicles, and policies to encourage safe and active transport such as walking and cycling.
The WHO says that globally in 2016, seven million deaths were due to the effects of household and ambient air pollution. The vast majority of these were in low and middle-income countries. “If we want to protect our children, we need to make sure the air they breathe isn’t toxic,” said Sonja Ayeb-Karlsson, a global health specialist at Britain’s Sussex University who worked on the Lancet study.

Topic: Physics Nobel rewards work on climate change, other forces
Three scientists won the Nobel Prize in physics Tuesday last week for work that found order in seeming disorder, helping to explain and predict complex forces of nature, including expanding our understanding of climate change.
Syukuro Manabe, originally from Japan, and Klaus Hasselmann of Germany were cited for their work in developing forecast models of Earth’s climate and “reliably predicting global warming.” The second half of the prize went to Giorgio Parisi of Italy for explaining disorder in physical systems, ranging from those as small as the insides of atoms to the planet-sized.
Hasselmann told the Associated Press that he “would rather have no global warming and no Nobel Prize.” Calling climate change “a major crisis,” Manabe said that figuring out the physics behind climate change was “1,000 times” easier than getting the world to do something about it.
All three scientists work on what are known as “complex systems,” of which climate is just one example. But the prize went to two fields of study that are opposite in many ways, though they share the goal of making sense of what seems random and chaotic so that it can be predicted.
The research of Parisi, of Sapienza University of Rome, largely centers around subatomic particles, predicting how they move in seemingly chaotic ways and explaining why. It is somewhat esoteric, while the work by Manabe and Hasselmann is about large-scale global forces that shape our daily lives.
Parisi “built a deep physical and mathematical model” that made it possible to understand complex systems in fields as different as mathematics, biology, neuroscience and machine learning.
