Airlines have tamped down on carbon emissions by flying planes at higher altitudes. But this comes at a cost: the higher-flying aircraft are creating more contrails that last longer, worsening the industry s impact on climate change, a new study found. This doesn t mean that more efficient aircraft stanley cup are a bad thing ndash; far from it, as they have lower carbon emissions per passenger-mile, said Edward Gryspeerdt, stanley cup the lead researcher, in a statement. However, our finding reflects the challenges the avia stanley cup tion industry faces when reducing its climate impact. Contrails mdash; short for condensation trail mdash; are the white streaks in the sky behind planes. Airplanes create the lines of water vapor when they fly through high altitude humidity zones. An MIT study from March of this year found that contrails account for just over a third of the aviation industry s contribution to climate change. Contrails trap heat in the atmosphere, which in turn warms the planet.Private jets, already heavily scrutinized for high carbon emissions, represent a big part of the contrail problem. Imperial College London researchers found that the small planes produce similar-sized contrails to their bigger counterparts. We already know that these aircraft create a huge amount of carbon emissions per passenger so the super-rich can fly in comfort, said Gryspeerdt in a statement. Our finding adds to concerns about the climate impact caused by private Qdjr Surgeon General: Things are going to get worse before they get better
