My pursuit of Chattanooga’s major environmental story branches into a new prospect: That sky stripes are an emission coming from environmentally friendly fuels that may be a new way for the airline industry to obtain pollution credits. If sky stripes create cloud cover, might not the polluting airline industry be able to obtain credit from Uncle Sam for his task in helping save the planet? At the same time, air pollution from jets is warming the planet because the smog blanket sky stripes help create trap heat close to the earth’s surface.
Sky striping over Chattanooga seems to have slacked off since January, with jet activity dates in April as follows: April 1, 5, 8, 9, 11, 12, 19, 23,24, 28 — that’s 10 days out of 30. March had 11 days, February 9 days and January 16 days.

By Jim Lee
Chemtrails and contrails are both terms referring to clouds made by jet aircraft, which spread out and cover the sky.
I use the term “contrail” while debating scientists because using the word “chemtrail” may cause them to discount the value of my words.
I use the aggressive term “chemtrail” while engaging the public because the neutral word “contrail” tends to get you labeled as a stratospheric aerosol geoengineering debunker, or someone who insists that sky plumes are mere water vapor, not part of any federal policy, rule or program.
The debate over sky plumes or white tattoo checkerboards on many horizons can be framed two ways, each of which intersects with the other.
Are “rogue geoengineers” or the military intentionally spraying material to create clouds that cover the sky as part of a military or deep state response to global warming? Or is the smogpot mess in virtually every quadrant of the world’s skies just the result of a dirty, unregulated industry doing what industry often does — polluting while profiting?
Is the messy, hazy and crisscrossed sky official pollution pretending to save the planet from sunlight, or is it the hapless result of dirty industry?
If there is a chemtrail conspiracy, it boils down to one thing: Intent.
What makes a contrail?
Due to the overwhelming amount of propaganda surrounding the topic of contrails, I have researched contrails for two years to “clear the air” as a part of something I call “Operation Clarity,” and this essay is a wrapup.
To start, let’s clarify that contrails exist, and some persist in the air and form clouds.
What is in a contrail?
Soot, sulfur and water.
Carbon black dust, or soot, is coated in sulfur and shoots out of the rear of the jet engine.  Water sticks to these sulfur-coated soot particles and clouds form.
The more sulfur and soot there is in the jet exhaust plume the more likely you are to see contrails. The other thing you need is saturation, which is provided by large bodies of water in the sky called ice supersaturated regions or ISSRs.  As jets fly through these frozen water bubbles in the sky, sulfur-coated soot and water thrust backward from the jets attach to ice in a way that baffles scientists:
Aerosol-cloud interactions are one of the main uncertainties in climate research. Up to now a lot of research has been conducted on aerosol-cloud interactions in warm clouds. The impact of aerosols on ice or mixed-phase clouds is much less understood. 
Are contrails a bad thing?
Yes, they are heating the planet. Did you know that the section covering contrails for the last IPCC report in 2007 was co-authored by at least five geoengineering advocates?  The lead author of that report is Olivier Boucher, and his group’s conclusion is “large uncertainties associated with spreading rate, optical depth, ice particle shape and radiative transfer. A low confidence is attached to this estimate.” Four years later, Boucher makes this statement:
Contrails formed by aircraft can evolve into cirrus clouds indistinguishable from those formed naturally. These ‘spreading contrails’ may be causing more climate warming today than all the carbon dioxide emitted by aircraft since the start of aviation. 
The climate change uncertainties surrounding aerosols, contrails, and ship tracks  seriously undermine the credibility of climate change models as they are clearly missing LARGE portions of crucial data to make accurate predictions.  More importantly, Geoengineering SRM proposals using aerosols are truly gambling with the weather as scientists do not understand the first thing about how those aerosols affect climate.
Airlines want to get credit for contrails
With increasing government pressure on the marketplace in the name of environmentalism, the aviation industry faces a hefty “carbon tax” bill unless it can find a way to turn polluting contrails into “carbon credit” and a benefit to public policy and its war on global warming.
In order to “green” aviation and rebrand dirty fossil fuels as “climate friendly,” the oil tycoons are switching exotic blends of biofuels and selling them to airlines. 
For the past two years, the FAA  has tested these fuels to see how biofuels effect contrail production.  Results are expected to be made public.
It would appear that these new biofuels are low or no-sulfur — meaning less polluting.
Cleaner jet fuel might appear to be a good thing.
But the rising pressure of the war on global warming has fired up pressure in the opposite direction — that of increasing the pollution caused by jets in the name of solar radiation management and sun-dimming technology.
These organizations and scientists are proposing adding sulfur to the fuel to ostensibly cool the planet with a sun-reflecting haze.
To sulfur or not to sulfur, that is the question?
The National Academy of Sciences, in its February study Climate Intervention: Reflecting Sunlight to Cool Earth, discusses sulfur aerosol injections to enhance the planet’s albedo, or reflectivity.
The European Union recently took bold steps to address the jet aircraft pollution,  and under threats of lawsuits the EPA is deciding whether to regulate flight pollution.
Recently the Environmental Protection Agency took a step towards adding aircraft emissions to the list of regulated pollution sources. In a statement  the EPA said it will study the issue of greenhouse gas emissions from aircraft, the first step in the regulatory process, and release its findings by April 2016. If the agency finds airline emissions to be a risk to public health or the environment, it will begin the process of crafting rules. The rules would make airplanes subject to carbon emissions guidelines in a process similar to the one currently underway for vehicles and power plants.
A battle is brewing over contrail as either blessings or curse. Will the aviation industry biofuel its way out of carbon tax oblivion by eliminating sulfur from fuel and eliminating contrails/chemtrails? Or will it turn those contrail frowns upside down by DEMANDING credit for its pollution, which is ostensibly saving the planet by dimming the sun? 
Contrails vs. solar energy
Tinkering with the fuel in jets is, perhaps, the geoengineering program that many skywatchers around the world are seeing. This massive geoengineering program is marked by compartmentalization, is a New Manhattan Project, and is a battle between those who would protect the aviation industry’s bottom line at any environmental cost and those who would intentionally take advantage of polluting contrails for monetary gain via pollution tax credits.
Fossil fuel oligarchs rebrand their poison as “green biofuels” and everyone discusses carbon dioxide, not contrails power to trap heat even as they block sunlight.
Geoengineering SRM proponents such as David Keith and Ken Caldiera overlook the proposition that jet-laid contrails and shipping cloud-trails are man-made sun-blocking killers of solar energy.
If there is a conflict over “chemtrail conspiracy,” it is between fossil fuel vs solar. Solar profits when sunlight hits the ground with full intensity, unimpeded by manmade hazes.
There is a battle in the sky and for the hearts and minds of members of the public.
Americans and people all around the world need accountability from regulators, transparency from the fossil fuel industry with its trade secrets, honesty from the IPCC and climate model yahoos, and the fresh air implied in clear sky overhead.
