It shows extinctions of some species of marine animals on a 62 million year cycle.
the rate of extinction has varied from 70% at the highest to 15% at the lowest. There are also peaks of extinction which miss the cycle entirely and points on the cycle which do not peak.
It has been suggested variously that extinction events occurred periodically, every 26 to 30 million years,[21] or that diversity fluctuates episodically every ~62 million years.[22] Various ideas attempt to explain the supposed pattern, including the presence of a hypothetical companion star to the sun,[23] [24] oscillations in the galactic plane, or passage through the Milky Way's spiral arms.[25] However, other authors have concluded the data on marine mass extinctions do not fit with the idea that mass extinctions are periodic, or that ecosystems gradually build up to a point at which a mass extinction is inevitable.[4] Many of the proposed correlations have been argued to be spurious.[26][27] Others have argued that there is strong evidence supporting periodicity in a variety of records, [28] and additional evidence in the form of coincident periodic variation in nonbiological geochemical variables.

Here's where you go wrong. What you are calling "chemtrails" are contrails. Ice crystals which have condensed and frozen.
Here's why I'm relating this back to chem trails: chem trails are a phenomenon that occurs in the sky,
Then most of what you read and watch is nonsense. You should try reading and watching something factual. There is no evidence that contrails have high concentrations of aluminum and barium.
Most of what I have read and watched about chem trails talks about high aluminum and barium content in the trails, hence the reason I mentioned aluminum.
Do you know how hot a meteor is when it reaches the stratosphere?
it could heat up the aluminum to ignition temperature, thereby causing the meteor to burn up sooner than normal.
No. We do not.
What we do know for certain is the skies are being sprayed with something.

I acknowledge that the entire chem trail subject is based on speculation, but that is our only option, since we are not being told anything.
No.
The fault lays squarely with the scientists and institutions who make these spectacular “headlines” if there is something wrong with their “research”, not with members here who believe and repeat what these scientific organizations release as facts...
There was still another to pass by on Friday.
