Airplanes of the future will have to carry lighter loads more often thanks to global warming, according to two scientists at Columbia University, New York. They reached their conclusion by creating models which predicted that by 2060 there will be more warm days but no commensurate technological advances in the aviation industry.
The two scientists, Coffel and Horton, looked at a phenomenon known amongst pilots as ‘density altitude’, which affects a plane’s ability to take off. Essentially, on hotter days the air is less dense, making it harder to get a plane airborne. It is a particular problem at airports with short runways, as the planes will take longer to lift off.
Commercial aviation overcomes the problem by issuing weight restrictions at the airport on particularly hot days. Coffel and Horton sought to predict how many more weight restricted days there will be by 2050-2070, and decided, through use of models, that the "number of weight restriction days between May and September will increase by 50-200 percent at four major airports in the United States by 2050-2070," and that "these performance reductions may have a negative economic effect on the airline industry."
Their solution is for the aviation industry to start "planning for changes in extreme heat events" to "help the aviation industry to reduce its vulnerability to this aspect of climate change."
But as Anthony Watts of the blog Watt's Up With That points out: "Of course they are assuming that [their] models produce an accurate output, and that airplanes of the 2050-2070 era have the same airfoil efficiency and take-off power of today." Neither of which are by any means certain.

I wonder how long it will be before they go back to their global cooling meme?
“Political correctness is a doctrine, fostered by a delusional, illogical minority, and rapidly promoted by mainstream media, which holds forth the proposition that it is entirely possible to pick up a turd by the clean end.”

They don't dare do that. Last I heard, we are in a global warming 10 year pause. "Oh what fools these mortals be."

Is it just me or do we have way too many (6-7 million at last count) scientists/self proclaimed scientists in this country?
It seems a good percentage of them can only make a living taking taxpayer money from certain government agencies to spout their totally useless propaganda/BS/drivel. (Some government funding agencies, including America’s National Institutes of Health, which dish out $30 billion on research each year).
And its not just MGW it seems to be other issues too!
