Story summary

The study finds contrails within natural cirrus clouds contribute ten percent to visible contrail warming.
Researchers analyzed about 40,000 aircraft–cloud encounters, linking higher air traffic to warming.
The study suggests routing flights through cirrus clouds may not effectively reduce aviation's climate impact.
In the Arctic, rapid warming links melting ice, atmospheric chemistry, and human pollution, calling for integrated climate models.
Both studies urge action on aviation's climate role.
