Jet condensation trails may cause climate change: NASA

 

 

 

WASHINGTON (AFP) Apr 28, 2004Condensation trails from the engine exhausts of jet aircraft may have provoked the warming trend in the climate seen from 1975 to 1994, a NASA researcher said Tuesday. "This result shows the increased cirrus (cloud) coverage, attributable to air traffic, could account for nearly all of the warming observed over the United States for nearly 20 years starting in 1975," said Patrick Minnis, a senior research scientist at NASA's Langley Research Center in Hampton, Virginia. Such "contrails", which are believed to actually cause the increase in cirrus cloud according to the study's findings, would "add to, and not replace, any greenhouse gas effect," he said. During the same period, "warming occurred in many other areas where cirrus coverage decreased or remained steady." A one percent increase per decade in cirrus cloud cover above the United States was "likely" due to air traffic-induced contrails, he said. The study, published in the April 15 edition of the US review, the Journal of Climate, demonstrates that human activity has a visible and significant impact on cloud cover and, therefore, on climate," Minnis said. "It indicates that contrails should be included in climate change scenarios," the National Aeronautics and Space Administration researcher added.

This is pure propaganda spin. A contrail does not form clouds as such and usually vanishes within 5 to 15 plane lengths behind the plane and do not linger. This is just spin to the sheeple to cover up for the chemicals that are being dumped on us that in many cases causes the whole sky to become overcast. Contrails are ice crystals that evaporate and will not cause global warming. Who are they trying to fool, I hope it wasn't you.

I agree. That is why I posted it. However, it is telling that NASA felt the need to publish anything regarding the subject. hmmmmm
