I am familiar with contrails and these tracks appear to be quite different.
What I am seeing is literally a relentless assault on the sky with planes zooming chaotically,
dropping thick veils of material. I have also experienced profound headaches and coughing that seem to coincide with the heavy spraying.
Amplified and long lasting expanding contrails sprayed in patterns, generally containing aluminum oxides and barium sulfides and other salts with very thin polymer threads to help keep them aloft, often with anti-mold chemicals to counter that effect from earlier trials.

Some people are more sensitive to it that others. To the gov't it is acceptable collateral damage to cool the planet. That part is at the holmestead.ca link. There is even more pictures there and pictures of the spray apparatus with testimony from several that were in the program. Not the illogic of conspiracy theory sites at all. It is real. It has a "good" purpose(to them). It is top secret with practiced suppression of witnessed events and measured aluminum and barium. It is denied as a matter of policy.
It is either that or actually stop using fossil fuels 90% like what should be done. Covering symptoms won't hide it all.http://www.wunderground.com/climate/PETM.asp
Note that in Fig 2 and Table 1 the current rate is BEFORE the tipping points of open ocean self warming, tundra (then oceanic several hundred years later) methane hydrate deposits self release positive feedback loops are established in 3 to 11 years. AFTER, it will go up even faster in rate of warming!!!
There is at least 20% more carbon now than PETM ("Storms of My Grandchildren", Hansen 2009).
