[insert image of the 7 contrails] Caption: A collage of 7 individual images captured over a period of 40 seconds showing some changes in the iridescent colors and also in the contrail shape.

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.

The claim: Video shows contrail and 'chemtrail' next to each other A May 10 Instagram video (direct link, archive link) shows a blue sky with two white streaks across it. One is significantly ...

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 ...
