Vapour Trails and Greenhouse Gas

[ORAC]

I fear someone is being disingenuous,

The text of the original article did not state it was limiting itself to discussing short haul flights. On the contrary, it went out of it's way to say that, "But global air traffic is growing by around 3.5 per cent per year, and many of those extra flights are long-haul, high-altitude, contrail-forming journeys."

The figures are stated as being a simulation of that over the busiest part of Europe, taken together with the comment above, it is an obvious attempt to imply that it represents the future level of global long haul traffic.

I believe the point being made is valid. This was either badly written, with the comment about long haul traffic being an irrelevant aside, more probably it was introduced intentionally, even though unsupported by the data.
