Report Urges Action to Reduce Contrail Warming Effects
More study is needed to fully understand control formation and mitigation
A report from the International Air Transportation Association (IATA) describes how contrails contribute to global warming and recommends solutions that industry can use to minimize their effects. The report highlights the complexity of contrail science, noting gaps in understanding how contrails form, persist, and impact climate.
“The lack of high-resolution, real-time data on atmospheric conditions (particularly humidity and temperature at cruising altitudes) hinders precise contrail forecasting,” said the report. “Recent collaborations among meteorologists, climate researchers, airlines, and aircraft manufacturers have yielded new insights but underscored the need for enhanced data collection and air traffic network contributions.”
