"Aircraft condensation trails and the clouds that form from them may be causing more warming today than all the aircraft-emitted carbon dioxide (CO2) that has accumulated in the atmosphere since the start of aviation," the journal Nature Climate Change said in a statement of the findings.

That's a clever-clever, headline-catching statement which will sadly be inadvertently misinterpreted by climate change skeptics and deliberately misrepresented by climate change deniers. Some points to consider:

1) "aircraft-emitted carbon dioxide" is only a minute percentage of total carbon dioxide emissions.

2) Although aircraft contrails may be having a larger more warming effect than the CO2 emitted by those aircraft, contrails are temporary. If you grounded all aircraft today. the contrails would be gone in a week: the excess CO2 will linger for a thousand years or more.
