Climate Change is Disrupting Air Travel

The document outlines the bidirectional relationship between aviation and climate change, noting that global air travel emitted over 780 Mt CO2 in 2022 while simultaneously facing operational disruptions from the resulting warming. It identifies five primary climate-driven disruptions: coastal flooding threatening airport infrastructure, high temperatures reducing aircraft lift and capacity, increased lightning strike risks, shifting jet stream patterns affecting flight duration, and a rise in severe clear-air turbulence. The text emphasizes the need for the aviation industry to implement adaptation measures, such as coastal defenses and adjusted flight scheduling, to maintain safety and manage costs.

• Aviation contributes significantly to global warming, with emissions from global air travel and airport operations exceeding 780 Mt CO2 in 2022, representing approximately 2% of global energy-related CO2 emissions for that year. These emissions grew fourfold between 1966 and 2018.
• Climate change disrupts U.S. air travel through coastal flooding, extreme weather, and temperature increases; currently, weather is responsible for more than 75% of air traffic delays in the United States.
• Rising temperatures impact aircraft performance by reducing air density, which makes it harder for planes to gain lift. This can lead to weight restrictions on passengers, cargo, and fuel, or require longer runway distances for takeoff.
• Global warming is linked to increased aviation safety risks, including a projected 12% increase in annual U.S. lightning strikes for every 1°C (1.8°F) of warming and a 41% increase in severe clear-air turbulence over the U.S. between 1979 and 2020.
• Changes in the jet stream may alter flight durations in the Northern Hemisphere, potentially increasing the length of west-bound flights while shortening east-bound ones, which impacts fuel consumption and scheduling.
• The aviation industry must adopt adaptation strategies to mitigate climate risks, such as the Shoreline Protection Program at San Francisco Airport for coastal resilience, expanding runways, or scheduling flights during cooler times of the day.
