Right. When we can observe the trails starting and stopping abruptly, we know that it's some kind of geo-engineering.
Since they don't let us know what they are doing and why, we can conclude that they are acting without any interest in taking responsibility for their actions.
If I were to guess, they may attempt to increase the temperature in order to prove man-made global warming. Geo-engineering IS man-made so in a sense they would be correct, albeit deceitful.
The narrative of global warming was favored by Club of Rome as an excuse for implementing regulatory globalism.
If regulations are global, we have a de-facto world governanance (regulation monopoly without market competitors).
