Climate scientist Kim Cobb, who has committed to a flight-free career, gets two chances to publicly lobby for less air travel after the pandemic subsides. Her first is this Nature story, where Cobb, director of Georgia Tech's Global Change Program, argues for large conferences replaced by smaller, regional gatherings. She echoes that in The Guardian: "It will be nice to know that going forward, we have a viable, remote alternative for those trips where the climate costs, and associated injustices, outweigh the value for us as an individual."
