Bumpier Plane Flights Predicted as Global Warming Disrupts High-Altitude Air Currents

Wednesday, April 10, 2013

Passengers should get used to buckling up more on commercial flights in the coming years, because flying may get a lot bumpier.


A new study says that as a result of global warming, air currents at altitudes used by commercial airliners will become less stable, causing more turbulence.


“Our research suggests that we’ll be seeing the ‘fasten seatbelts’ sign turned on more often in the decades ahead,” study co-author Paul Williams of the University of Reading’s National Centre for Atmospheric Science in southeastern England told Agence France-Presse in an email.


Williams and his colleagues studied the North Atlantic jet stream, one of the world’s busiest air corridors, that sees an average of 600 flights a day between Europe and the United States.


They determined that if carbon dioxide in the atmosphere doubles within 40 years, turbulence could become 10%-40% more forceful at altitudes used by jetliners.


“Turbulence strong enough to make walking difficult and to dislodge unsecured objects is likely to become twice as common in transatlantic airspace by the middle of this century,” Williams added.


The study states that aircrafts currently spend about 1% of their flight time weathering strong turbulence, resulting in damaged planes, injuries to hundreds of passengers each year, and $150 million in annual costs to the airline industry.

GLOBAL WARMING MAY NOT BE MAN MADE Dr. Larry Vardiman (scientist and physicist) of the Institue for Creation Research says: "One possible scenario may be found in a recent series of articles by Henrik Svensmark and Nigel Marsh, cosmic ray specialists from Denmark, who have shown an indirect connection between galactic cosmic ray (GCR) intensity and global temperature.7,8,9 They are studying the influence of the Sun on the flow of GCR to Earth. The Sun's changing sunspot activity influences the magnetosphere surrounding the Earth permitting more GCR to strike the Earth during high periods of activity. When the Sun is active, the intensity of GCR striking the Earth is increased, causing more ionization in the atmosphere, creating more carbon-14, and possibly creating more cloud condensation nuclei (CCN). This increase in CCN, in turn, appears to create more low-level clouds which cool the Earth. When the Sun is quiet the GCR intensity striking the Earth is reduced, allowing the Earth to warm. Svensmark and Marsh have shown a striking statistical correlation between sunspot activity and global cooling and warming over the past 1000 years. The recent rise in global temperature may partially be due to current low solar activity supplemented by a recent increase in carbon dioxide concentration measured at Mauna Loa. The connection which still needs further study is the production of CCN and clouds by GCR." There is a good deal of science showing that global warming is not mad made. Yes, we still should have pollution controls, as we already do, but not to the extreme because it will unnecessarily hurt business.
