The IndependentScientists have used the no-flying period caused by the ash cloud to show for the first time that airports are themselves significant causes of pollution. Although long suspected, the fact that mass take-offs and landings are large pollution sources could never be proved before, because aircraft pollution could not be measured as separate from the pollution caused by vehicles operating near by.
The only actually news here is that we now have definite proof (real person speak for the scientific term: 'very strong indication') that airports need to be moved significantly further away from where people live and that air traffic needs to be heavily downsized -or that the air traffic industry needs to be taxed in order to pay for the health related costs it causes.
