Well you're right, seems there's no such thing as a nice conspiracy theory.
But even still, it seems globally, contrails/chemtrails don't seem to have an affect.
C'mon Chadwickus, for someone that usually expects others to present hard evidence, how can you possibly read this article and draw the conclusion
that 'globally, contrails/chemtrails don't seem to have an affect'
Firstly, the aviation industry does not deny that 'globally' it does have an effect on the envroment and its own estimate is that the industry is
rersponsible for 3% of the warming caused by greenhouse emmisions. People outside the industry claim the figure is much higher.
Secondly, lets look at how dust, soot and smoke is removed from the Stratosphere -
The exact timescale for how long this smoke remains, and thus how severely this smoke affects the climate once it reaches the stratosphere, is
dependent on both chemical and physical removal processes. The physical removal mechanisms affecting the timescale of smoke particle removal are how
quickly the particles in the smoke coagulate and fall out of the atmosphere via dry deposition, and to a slower degree, the time it takes for
solar radiation pressure to move the particles to a lower level in the atmosphere. Whether by coagulation or radiation pressure, once the particles
are at this lower atmospheric level cloud seeding can begin, permitting precipitation to wash the smoke aerosol out of the atmosphere by the wet
deposition mechanism. The chemical processes that affect the removal are dependant on the ability of atmospheric chemistry to oxidize the smoke, via
reactions with oxidative species such as ozone and nitrogen oxides, both of which are found at all levels of the atmosphere.[
So given the amount of solar activity recently and almost unprecedented rainfall around the globe, one could expect the stratosphere to be reasonably
clear. That doesn't change the fact that during this process Ozone will also be depleted. In fact, just for the record, a recent paper provides
evidence that an eclipse itself has a strange but significant effect on Ozone.
So, as I'm sure you are aware, the fact that someone says the stratosphere is reasonably clear in no way provides proof that Contrails/Chemtrails do
not have a global effect. There are many different arguments as to what Chemtrails are so I chose one which is the global weather modification
programs/war. This is having significant global consequences and the cummulative effect is only now beggining to be felt in parts of the world.
With the amount of money and research going into this subject of pollution in our atmosphere there are new papers being published almost daily. You
might find some intersting -
