The Rise of Climate Change and Its Impact on Aviation
Climate change is an undeniable global challenge, and its effects are being felt across industries—including aviation. From increased turbulence and flight delays to the need for sustainable fuels, the changing climate is reshaping air travel as we know it. This article explores the keyways rising temperatures and extreme weather are impacting aviation, with insights from reputable sources.
Rising Temperatures and Aircraft Performance
One of the primary ways climate changes is affecting aviation is through rising global temperatures. Warmer air is less dense, which reduces the lift generated by aircraft wings. This forces planes to require longer runways for take-off or to reduce their payload (passengers or cargo).
A study published in Nature Communications found that approximately 5% of current anthropogenic climate change is attributed to global aviation, and this number is expected to increase as other sectors decarbonise (Nature Communications).
Airports located at higher elevations, where air is naturally thinner, are already experiencing these challenges. For example, in 2017, over 40 flights at Phoenix Sky Harbour International Airport were cancelled due to extreme heat exceeding 48°C, which made it unsafe for aircraft to take off (BBC).
Increased Turbulence and Passenger Safety
Studies indicate that climate change is increasing turbulence levels, making flights bumpier and potentially more hazardous. Research from the University of Reading suggests that clear-air turbulence—a type of turbulence that occurs without visual warning—could increase due to shifting jet streams caused by climate change (University of Reading).
This increase in turbulence not only affects passenger comfort but also poses risks to crew and aircraft safety. Injuries from turbulence-related incidents are on the rise, leading airlines to adjust flight paths and invest in improved forecasting technology (CNN).
Extreme Weather Events Disrupting Flights
Extreme weather events such as hurricanes, storms, and heavy rainfall have become more frequent due to climate change. These events result in significant flight cancellations, delays, and disruptions to global travel networks.
For example, in 2022, Hurricane Ian led to the cancellation of over 2,000 flights across the U.S., costing airlines millions in revenue and stranding thousands of passengers (Reuters). Similarly, severe winter storms, intensified by climate shifts, have caused major operational challenges for airports in Europe and North America.
The Push for Sustainable Aviation
As climate change disrupts aviation, the industry is also under increasing pressure to reduce its carbon footprint. The aviation sector contributes approximately 2.5% of global CO₂ emissions, and by 2050, their share could rise to 22% (Nature).
Some key advancements include:
- Sustainable Aviation Fuel (SAF): SAF can reduce carbon emissions by up to 80% compared to conventional jet fuel. Airlines like British Airways and KLM have already started incorporating SAF into their operations (IATA).
- Electric and Hybrid Aircraft: Companies like Airbus and Boeing are investing in electric-powered aircraft to reduce reliance on fossil fuels (Airbus).
- Improved Air Traffic Management: More efficient routing can reduce unnecessary fuel burn and emissions (EUROCONTROL).
Recruitment Challenges and Opportunities in Aviation
The evolving aviation landscape has also impacted hiring and recruitment. With new technologies and sustainability initiatives, the industry is experiencing a skills shift. Airlines and aerospace companies are increasingly looking for professionals in:
- Green aviation technology and SAF development
- Climate impact research and forecasting
- Aerodynamics and aircraft efficiency optimisation
