Should we divert planes in an attempt to prevent bad weather?

Aircraft contrails stoke warming, cloud formation | Reuters
(Reuters) - Aircraft condensation trails criss-crossing the sky may be warming the planet on a normal day more than the carbon dioxide emitted by all planes since the Wright Brothers' first flight in 1903, a study said on Tuesday.
...
He said the findings might bring changes in air traffic control, for instance diverting planes from regions or altitudes where air moisture was high and favoured cirrus formation.

But a problem was that any benefits of fewer contrails might be cancelled out by higher fuel use on longer routes.

He also said that it could spur a novel engine concept that would seek to condense some of the water vapour "before it leaves the engine. The condensed water could be vented in the form of large ice crystals or droplets that would fall quickly through the atmosphere."

Nonsense!
Con trails do have a Very Small effect on local temperatures, but it is the other way around.
They reflect sunlight and thus reduce the local temperatures.

Why don't they just be honest?
They want freedom and prosperity made illegal and will tell whatever lie they think we will swallow.
Sorry Not swallowing that silly tripe.

What millions of people around the world are witnessing everyday with their
very eyes -asking questions towards ALL directions without getting ANY answers-
and confronted as "conspiracy theories", is now being presented to us as "studies"...
It is all deliberately done. In front of our eyes and under our nose...
Ther is no need for "novel engine design" or "divert planes costing more fuel".
They just have to be stoped from doing it.
No more wasted words here...
This operation, clandestine -for ALL governments but widely known as Chemtrails -for the rest
of the world, is taking place for at least 15 years, is called Geoengineering,
(the modern, more 'trendy' term for Weather Manipulation)and IS the MAIN cause
for the so called "global warming" or "climate change" or "climate disruption"..., you name it...!

Another claim that has no basis in fact. And any additional equipment to condense the water in the jet exhaust will mean extra weight and extra fuel burned.

Creation of artificial clouds (through chemicals) and other weather parameters in order to
manipulate or alter the weather has been "evolving" for more than 60 (!) years.
The deliberate use of jet engine condensation to create hi-altitude artificial clouds (or 'cirrus')
that are known to trap outgoing heat from earth surface, is not a "claim", it's a FACT.
Whatever changes are made in hi-altitude cloud cover(not cirrus) -beyond Nature does- can severely alter
the weather patterns of the whole planet. And this not a "claim", it's a FACT.
For at least 15 years this -now globally- everyday 'pounding' is changing everything.
Destroying the earth we live on and the air we -and our children- breathe...
And is delibarate...!
