Researchers from Kyushu University have found that rising carbon dioxide levels in Earth's atmosphere may disrupt high-frequency radio communications that support air traffic control, maritime communication, and broadcasting.

The study shows that while global surface temperatures increase with more CO2, the ionosphere at heights around 100 km above sea level actually cools. This cooling thins the air, enhances wind circulation, and destabilizes satellite and debris orbits while creating plasma irregularities that interfere with radio waves.

One such irregularity, the sporadic-E (Es) layer, forms between 90 and 120 km in altitude. "Es are sporadic and difficult to predict. However, when they occur, they can disrupt HF and VHF radio communications," said Professor Huixin Liu. Their simulat
