NEW STUDY finds feedback loop between air travel and climate change:

By analyzing 34 global climate models, [researchers] found that global warming is expected to increase average west-to-east winds. They calculated that such a change would add about 5.5 flying hours to each daily round-trip, per carrier, per route, per year. For all four airlines, that added up to an annual cost of US$1.4 million on fuel and 4.6 million kg of carbon dioxide emissions.

Except that they forgot that west-to-east flights are correspondingly more efficient and thus emit less CO2.

Junk 'science'.
