The thing is, when he gave that advice, the evidence was in that climate change was going to globally destabilise the climate if we didn't our reduce greenhouse gas emissions, but not so obvious that the emissions from diesel engines would be locally so bad for health. That's what scientists do: go where the evidence takes them.
Incidentally, global warming induced changes, such as the
meandering jetstream, and increased water vapour in the atmosphere, are not going to improve flying conditions for GA.
