Jet stream and climate change: global warming may make transatlantic flights even longer

The video discusses how changes in meteorological conditions affect the jet stream, which is expected to become 15% faster in winter due to global warming. This change will shorten flights from New York to London but lengthen those from London to New York, increasing overall flight time by 2000 hours annually. This results in higher fuel costs and CO2 emissions, equivalent to the annual output of 7100 British homes.
