“By simply avoiding airspace with the conditions conducive to persistent contrail formation, the impact of aviation on climate could be reduced by 80 percent, Fletcher said.”
Might this be by flying at lower altitudes (which increases fuel consumption per hour AND has the added problem of tankering additional fuel on nearly every flight just in case contrails are reported)? Doe it also mean vectoring around contrail-producing areas to avoid the “problem”?
Both increase the carbon emissions of the flight. Seems like there is the possibility of making the problem WORSE–but that doesn’t seem to bother the “professional (woke) worriers.”
