Airlines may be forced to cut their loads of passenger, cargo, fuel due to global warming: Here's why

New Delhi: More frequent heat waves and rising temperatures due to global warming may ground up to a third of airplanes worldwide during hot days in decades to come with some airports in New York and Dubai likely to be hard hit, a study showed on Thursday.
Airlines may increasingly be forced to cut their loads of passengers, cargo or fuel in order to take off safely because warming air lessens the ability of airplane wings to generate lift, according to U.S. researchers.
Worldwide average temperatures are expected to climb some 5.5 degrees Fahrenheit (3 Celsius) by 2100, researchers said.
But it is more prevalent heat waves that pose a larger threat to the airline industry, they said in a study published in the journal Climate Change.
Annual maximum daily temperatures at airports could rise by 7 to 14 degrees Fahrenheit (4 to 8 Celsius) by 2080, they found, leading to more costly delays in take-offs or cancellations.
During the hottest parts of the day, between 10 and 30 percent of fully loaded planes may have to dump weight in order to begin their journey.
The phenomenon could force the aviation industry to brace for thinner profit margins, the authors said.
A full 160-seat aircraft trying to safely take off in searing heat may, for instance, need to remove 13 passenger, said the study.
