Here is an interesting article that illustrates how poorly LIE-berals are handling environmental issues. With some comments of my own in brackets):
Empty skies after 9/11 set the stage for an unlikely climate change experiment.
By Patrick Cain National Online Journalist, News Global News. Sept 12, 2016.
(Some reader swill recall my previous posts- with information taken from Cdn Geographic magazine about how the 9/11 terror attack grounded 25 percent of the worlds airline fleet- and a year later the air across the planet was measurably cleaner! This article expands on that old report!)
On the morning of September 11, 2001, officials at the U.S. national air control centre couldn’t make out what was happening, at first.
As controllers watched the second plane crash into the World Trade Center complex just after 9 a.m., however, it became clear that the first one hadn’t been a spectacular accident, but something much more sinister. Planes were becoming fuel-filled missiles. How many? Nobody knew.
Officials at the U.S. Federal Aviation Administration did the only thing they could think of to try to control the situation: ordering every aircraft in U.S. airspace, about 4,000 of them, to land somewhere, anywhere, immediately.
Canadian officials followed. Airports in Atlantic Canada quickly filled with thousands of bewildered people who had been flying west across the Atlantic from Europe, but found themselves stranded in Goose Bay, Labrador or Stephenville, Nfld.
Within a few hours, the skies across the continent were empty except for military aircraft. Here’s what it looked like: Civilian air traffic wouldn’t resume for three days.
Thousands of jet aircraft leave contrails over North America every day, especially over the U.S. eastern seaboard and the Midwest. Contrails are created when water vapour in hot air blasted out of jet engines freezes in the intense cold of high altitudes.
Do all those jet trails change weather patterns? It’s hard to tell, normally. But with the once-busy skies silent and empty, the scene was set for a giant experiment.
“I remember walking to and from my office (in the days after the attacks) and thinking how incredibly clear the skies were,” Andrew Carleton, a geographer at Pennsylvania State University, later wrote.
About a year after the attacks, Carleton, David Travis, a geographer at the University of Wisconsin, and another colleague argued in a paper that thin clouds created by contrails reduce the range of temperatures. By contributing to cloud cover during the day, they reflect solar energy that would otherwise have reached the earth’s surface. At night, they trap warmth that would otherwise have escaped.
The effect during the three days that flights were grounded was strongest in populated regions where air traffic was normally densest. The increase in range came to about two degrees Celsius.
(IN other words- it isnt just the carbon monoxide and other gases that engines produce that we must worry about! The water vapour being generated is also a SERIOUS ENVIRONMENTAL THREAT! And the latest jet engines have the ironic quality of being both more fuel efficient and more environmentally unsound since the new engines spit out larger lumps of carbon that water droplets coalesce around more easily than the smaller lumps from older engines! The new more fuel efficient engines actually accelerate the production of contrails! And the new Airbus 380`s actually fly few thousand ft higher where the air is even colder and condensation is further facilitated!)
Other studies have tended to back up the research. In 2011, British scientists wrote that an air raid in May 1944 involving over 1,400 aircraft measurably lowered daytime temperatures in England. In that case, the situation was the reverse of 9/11 – large-scale air travel was unknown, and dense concentrations of large planes were rare.
In 2004, NASA scientist Patrick Minnis wrote that “increased cirrus 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.”
Minnis also argued that a steady increase in cloud cover over the United States, about one per cent a decade, was due to increasing air travel. He also found that increases in cloud cover were more pronounced in populated areas, and stronger in winter, when contrails are bigger.
The warming effect happened because the high-altitude clouds that contrails created tended to trap warm air, Minnis wrote. On balance, though contrails can both warm and cool, there is more of a warming effect.
A Penn State study compared regions of the United States where contrails tended to form more strongly with areas where they didn’t. The more contrail-heavy the area, the less the variation between daytime highs and nighttime lows tended to be.
In a 2005 paper, physicist Robert Noland of Imperial College London suggested that restricting airliners to 31,000 feet, and 24,000 feet in winter, could reduce the formation of contrails. Though lower-flying planes would be less fuel-efficient, Noland argued that the increased fuel consumption would be more than made up for by less contrail-linked clouds as a cause of global warming.
(So we now have solid proof that airplane contrails are contributing to global warming and are a major source of air pollution - just as the old articles from Cdn Geographic magazine claimed. Therefore the LIE-beral carbon crap and trade tax will do NOTHING to clean the air- nor save us from global warming! As I and many others have repeatedly pointed out- LIE-beral crap and trade just cleans wallets and leaves the dirt in the air!)
(The carbon crap and trade tax is nothing more than a LIE-beral gravy grabbing scam that will ensure that civil service union Hogs can continue to spew their major masses of carbon from their gas guzzling toys and will continue to fly to places like Florida- at vast environmental cost- for those vitally important rounds of golf! And we have yet to discuss the environmental degradation brought on by heavy use of pesticides, herbicides and fertilizers at those golf courses- which all to often run into the nearest body of water after a rain storm- with MORE ugly environmental results!)
