More polluting aircraft contrails in the atmosphere
El Universal | 30.03.2011 | 7:33
Federal District contrails of condensed water left in its wake planes are more dangerous to the atmosphere than all the carbon dioxide emitted since the beginning of aviation, says a study published in the latest issue of the supplement "Climate Change of the journal Nature.
Under certain weather conditions, leaving long trails behind the aircraft become cirrus ice crystal compounds in the troposphere, a phenomenon that can have significant effects on the natural process of climate.
These artificial clouds may hinder the appearance of natural cirrus and to replace them altogether in some cases.
Contrails and cirrus clouds are causing artificial, like carbon dioxide (CO2), a high radiation force, ie its concentration causes an increase in temperature of the atmosphere, which is its greatest danger .
The impact of aviation on climate change has not been established yet clear, partly because they have not been precisely quantified the effects of scientifically known in English as "radiative forcing", say researchers Aerospace Center The investigators from Germany, Ulrike Burkhardt and Bernd K?rcher.
German scientists stress the importance of providing a basis for developing strategies to reduce the impact of aviation on climate change, which will be essential to take into account the effects of contrails.
K?rcher Burkhardt and propose that the planes avoiding routes where weather conditions facilitate the formation of artificial clouds and water vapor reduce expelled into the atmosphere by aircraft
