Flight times across Atlantic to be impacted by alterations to jet stream caused by climate change, research suggests

Published on Wednesday, a latest study suggested that flight times throughout the Atlantic are going to be impacted by changes in the jet stream, caused due to climate change.

Most part of the study has focused on the ones that have seen increased journey times, probably just a matter of minutes per flight, and the following financial expense to the airlines and the consumer.

However, amid a saga as pervasive and well-known as climate change, is there deeper implication to be gleaned or not?

In an email interview with The Christian Science Monitor, Kris Karnauskas of the Atmospheric and Oceanic Sciences department, University of Colorado, said that the work isn't just regarding the airline bottom lines or the cost of airfare to the consumer, instead it is about attempting to understand the multifaceted feedbacks involved in climate change.

The study, appearing in Environmental Research Letters, has discussed the overall rise in jet fuel consumption foreseen by the research, and the pollutants being emitted into the skies. It said that the decrease in flight times in one direction is inadequate to negate the increase in the opposite way.

In the abstract of the study, Paul Williams of the Department of Meteorology at the University of Reading, United Kingdom wrote, "Even assuming no future growth in aviation, extrapolation of our results to all transatlantic traffic suggests that aircraft will collectively be airborne for extra 2,000 hours each year, burning extra 7.2 million gallons of jet fuel at cost of US$ 22 million". Williams mentioned it would result into emission of an additional 70 million kg of carbon dioxide, which is equal to the yearly emissions of 7,100 average British homes.

According to Williams, there is a two-way interaction between aviation and climate change, which has brought them to the crux of the study: 'the vicious circle of positive feedback loops'.
