"Surging CO₂ Levels Threaten Stability of Shortwave Radio Communications"

Researchers at Kyushu University warn that rising carbon dioxide levels could disrupt shortwave radio communications, affecting vital systems like air traffic control and maritime communication.

• The study from Kyushu University highlights that while carbon dioxide increases global temperatures at Earths surface, it leads to unexpected cooling in the ionosphere 100 km above sea level.
• As carbon dioxide levels rise, the altered conditions in the ionosphere may jeopardize shortwave radio communications, critical for air traffic control and very high frequency maritime communications.
• Researchers utilized parts-per notation to measure carbon dioxide concentrations, emphasizing the need for monitoring atmospheric changes that could impact high frequency radio transmissions.
