Climate impact of clouds made from airplane contrails may triple by 2050 –

In the right conditions, airplane contrails can linger in the sky as contrail cirrus — ice clouds that can trap heat inside the atmosphere. Their climate impact has been largely neglected in schemes to offset aviation emissions, even though contrail cirrus have contributed more to warming than all CO2 emitted by aircraft since the start of aviation. A new Atmospheric Chemistry and Physics study found that the climate impact of contrail cirrus will triple by 2050.
