A group of scientists did actually come up with a "chemtrail" like plan to cool the planet... And it is horrific:
> To achieve a 2 °C result, the plan would inject 6.7 teragrams (6.7 billion kg/14.8 billion lb) of sulfur dioxide per year into each pole, calling for an eye-watering total of 13.4 teragrams (29.5 billion lb) of material annually.
The cost would be astronomical (but far more doable than other climate engineering methods) and the environmental cost of raining sulfuric acid over the arctic with an enormous fleet of planes would be unspeakable.
They clearly released the plan to illustrate how impractical climate engineering is, but I wonder if this is a seed for the wider chemtrail theory.
