Climate Change means no more flying for you after 2050

"Climate changes [sic] is getting so bad, researchers at Columbia University foresee 30 percent of flights being unable to take off by 2050."

ROFLMAO.

comes to about 4.5C iirc. That prediction can be refined upwards or downwards depending on "feedbacks" like ice-albedo and the effects of clouds, but no calculation I'm aware of changes the magnitude of the effect by more than a factor of 2 or 3 either

Agrees with my recollection as well. However, 4.5 / 3 = 1.5 which is close to the apparent change already observed.

The way I like to sum up my current view of the science on this presently is something like -

Has the earth recently warmed - probably.
Is this due to anthropogenic activity - maybe.
Would dramatically reducing CO2 emissions reduce the rate of warming - possibly.
Will further warming cause a non-recoverable runaway effect causing huge further warming - not very likely.

The book "The End of Doom" has a nice chapter on the state of the science as of a few years ago. And also covers how we may be better off allowing market processes to deal with this rather than trying a Luddite approach of trying to prevent emissions with regulations.

IMO likely better to try and figure out how to adapt to changes, since Mother Nature may throw us a doozy which will make any effects due to CO2 emissions look trivial by comparison.
