**Why Takeoffs at Airports Are About to Become Noisier**
*By Dwaipayan Roy | Sep 24, 2025 | 8:00 PM*
A recent study from the University of Reading has revealed that climate change could lead to increased noise pollution from departing airplanes around European airports. The research focuses on how rising air temperatures affect aircraft take-off patterns, finding that on average, departing aircraft climb angles will decrease by 1-3%, with some particularly hot days potentially reducing these angles by as much as 7.5%.
**Potential Impact on Noise Levels**
The study examined noise levels at 30 European airports, with a special focus on Airbus A320 aircraft—commonly used for short European flights—and how changes in climb angles affect noise pollution as the climate changes. Dr. Jonny Williams, lead author of the study, warned that climate change could expose thousands more people in London to noise pollution from departing aircraft over the next three decades.
Currently, approximately 60,000 people live within the 50dB noise footprint of a typical A320 aircraft in central London. However, due to climate change and increasing population density, an additional 2,500 people could be brought within this noise boundary in the near future.
**The Role of Sound Frequencies**
Dr. Williams explained that the problem is intensified by different types of sound frequencies. Low-frequency noise, which travels further distances, is expected to increase the most. These deeper sounds are particularly concerning as they can contribute to stress and disrupt sleep, raising public health concerns.
**Looking Ahead: Challenges Beyond Technology**
Despite advancements in engine technology aimed at reducing noise, Dr. Williams cautioned that rising temperatures caused by unchecked greenhouse gas emissions will make managing airport noise more difficult. Without decisive action on climate change, these environmental factors could outweigh technological improvements, exacerbating noise pollution issues around airports.
This study highlights the complex challenges climate change poses not only to the environment but also to urban living conditions, emphasizing the need for integrated approaches to mitigate its diverse impacts on society.
