Air travel has come under fire for its potential contributions to climate change. Most people probably assume that its impact comes through carbon emissions, given that aircraft burn significant amounts of fossil fuel to stay aloft. But the carbon released by air travel remains a relatively minor part of the global output—the impact of planes results from where they burn the fuel, not the mere fact that they burn it. A study in the brand-new journal Nature Climate Change reinforces that by suggesting that the clouds currently being generated by air travel have a larger impact on the climate than the cumulative emissions of all aircraft ever flown.
