A great deal of the rapid (in geological terms) climate change IS DUE TO HUMAN ACTIVITY. Aviation is a part of the problem, as is shipping, road transport and indeed human population.
Commercial aviation is playing its part in trying to reduce emissions, along with a fair bit of greenwash. There is more that could be done, not least curbing the mushrooming use of business aircraft. Also ensuring, as low cost airlines do, maximising loads on aircraft.
