Can’t stand the heat: Climate change might prevent airlines from flying full planes

Main image:  THIS summer America has experienced some of the most intense heatwaves in decades. In parts of southern Arizona the mercury has climbed to a sweltering 48°C. That has had an impact on the state’s infrastructure. Last month, a single day’s heatwave grounded dozens of planes. As global temperatures climb higher, such incidents are likely to increase.Climate change could have a dramatic impact on aviation across the world, according to a recently released paper by a team from Columbia University and Logistics Management Institute, a consulting firm. The researchers predict that as early as the middle of the century, some 30% of flights departing during the most blistering parts of the day will not be able to take off at their maximum weight because the hotter, less dense air will not provide enough lift.Of the 19 airports examined, Dubai and LaGuardia in New York are expected to see some of the worst effects. During the harshest hours, some of their aeroplanes could be grounded at their full weight around half the time, according to the paper. On average, airlines may have to cut as much as 4% of passengers or cargo to get their flights into the air at the hottest parts of the day. If carriers are forced to fly emptier planes, expect customers to pick up the tab through higher prices.The ...
