Alguém sabe da veracidade destas coisas? Será que andam mesmo a pulverizar a atmosfera com químicos?![]()
Uma coisa que não entendo na teoria dos contrails é o que se ganharia com a dispersão dessas substâncias químicas.
Se andassem a pulverizar a atmosfera com químicos para tornar as pessoas mais inteligentes seria um problema complicado e chato, mas como pulverizam apenas químicos para criar totós, menos mal. Darwin tratará deles.
High in the sky where the cirrus ice crystal clouds form, jet contrails draw their crisscross patterns. Now researchers have found that these elevated ice cloud trails can influence temperatures on the ground and affect local climate, according to a team of Penn State geographers.
"Research done regarding September 2001, during the three days (following 9-11) when no commercial jets were in the sky, suggested that contrails had an effect," said Andrew M. Carleton, professor of geography. "But that was only three days. We needed to look longer, while jets were in the air, to determine the real impact of contrails on temperature and in terms of climate."
The researchers report that the "diurnal temperature range was statistically significantly reduced at outbreak stations versus non-outbreak stations." In the South, this amounted to about a 6 degree Fahrenheit reduction in daily temperature range, while in the Midwest, there was about a 5 degree Fahrenheit reduction. Temperatures the days before and after the outbreaks did not show this effect, indicating that the lower temperatures were due to the contrail outbreaks.
