Taylor Swift threatened to sue Jack Sweeney for posting public data about the movements of her private jet.

I would expect that any one rich person's private jet contributes too little to global heating to be worth a moral fuss for its own sake. But all the private jets do amount to a significant (though small) fraction, and a campaign calls on people to stop using them.

Keep in mind, when considering the excuse repeated in the article, that many "carbon offsets" are bogus and that the system of ill-checked "carbon offsets" is of substantial help to the planet roasters in deflecting justified public pressure for true decarbonization.

This is why I call for a carbon tax rather than "carbon trading".
