Apocalypse of hunger: Scientists warn of a simultaneous decline in agricultural productivity worldwide

The researchers first examined the impact of the jet stream (air currents that drive weather patterns in many of the world’s most important crop-producing regions) and found that a strong labyrinth of the jet stream, which flows in the form of large waves, reduced harvest by seven percent. The products will have a significant impact on important agricultural regions in North America, Eastern Europe and East Asia.

The researchers also found that in the past, the phenomenon of jet stream was also related to the failure of agricultural products. One such case occurred in 2010, Kornhuber said, when fluctuations in the jet stream were linked to both extreme heat in parts of Russia and devastating floods in Pakistan, both of which damaged crops.

The study also examined to what extent the computer models evaluate the mentioned risks and showed that while the models perform well in terms of showing the atmospheric movement of the jet stream, they underestimate the severe effects caused by the mentioned streams.

“We need to be prepared for these kinds of complex climate risks in the future, and the models seem to be showing these risks very well now,” says Kornhuber, noting that the study should be a wake-up call about our uncertainties about the impacts of climate change on the food sector. They don’t give.”

On Monday, UN High Commissioner for Human Rights Volker Turk warned of a “truly terrifying” apocalyptic future of hunger and suffering, pointing to the impact of climate change on crops, livestock and vital ecosystems. In a UN debate on the right to food, criticizing the short-sightedness of world leaders, he said that more than 828 million people were facing hunger in 2021, and climate change could add another 80 million to this number by the middle of the century.
