Of course you wouldn't call it a contrail. You wouldn't call it anything because you wouldn't see it. It would have nothing to do with current nonsense "chemtrail" meme. So why call it a "chemtrail"? To stubbornly claim vindication?
It would still be a chemtrail. There's no way in hell you can call it a contrail that's for damn sure.
You're cool with spraying tons of sulfuric acid into the stratosphere each year?
No, you misunderstood what I said.
Looks like we agree on something.
I am 99% against it. The 1% being reserved in case of the absolute proof that the risks don't outweigh the benefits.
injecting sulfur into the atmosphere to slow down global warming is worthy of serious consideration, according to Nobel laureate Paul Crutzen from the Max Planck Institute for Chemistry in Germany and the Scripps Institution of Oceanography, University of California at San Diego. His thought-provoking paper1 is published in the August issue of the Springer journal Climatic Change, devoted this month to the controversial field of geoengineering.

In Crutzen’s experiment, artificially enhancing earth’s reflective powers would be achieved by carrying sulfur into the stratosphere on balloons, using artillery guns to release it. In contrast to the slowly developing effects of global warming associated with man-made carbon dioxide emissions, the climatic response of the albedo enhancement method could theoretically start taking effect within six months. The reflective particles could remain in the stratosphere for up to two years.
Geoengineering proposals were first developed in the middle of the 20th century. Relying on technologies developed during World War II, such proposals were designed to alter weather systems in order to obtain more favourable climate conditions on a regional scale. One of the best-known techniques is cloud seeding, a process that attempts to bring rain to parched farmland by dispersing particles of silver iodide or solid carbon dioxide into rain-bearing clouds. Cloud seeding has also been used in attempts to weaken tropical storms. In addition, the U.S. military suggested that nuclear weapons might be used as tools to alter regional climates and make certain areas of the world more favourable for human habitation. This proposal, however, was not tested.

Stratospheric sulfur injection
The formation of an aerosol layer of sulfur in the stratosphere would increase the scattering of incoming solar radiation. As more radiation is scattered in the stratosphere by aerosols, less would be absorbed by the troposphere, the lower level of the atmosphere where weather primarily occurs. Proponents believe that sulfur injection essentially would mimic the atmospheric effects that follow volcanic eruptions.

Just a helpful reminder, to the extent an OP ever can on a thread...but this is absolutely *NOT*, even a little bit, about the debate of Chemtrails or the back and forth any number of threads cover in great detail for how that specific word is used or thought of.
5. Proposed Timeline
This Framework contemplates a five phase approach that would likely achieve its objective of
guaranteeing prevention of catastrophic sea level rise within five years.
Phase I – Laboratory Research and Institutional Development: A consortium to
include the national leaders in SRM, would conduct preliminary research and technical
development work and draft a detailed plan to accomplish the necessary pilot scale
testing of SRM, to include funding requirements. The ideal leader of this consortium
would be Professor Wood (with significant assistance by Professor Caldeira and his
colleagues), and would include institutional experts such as Professor Barrett at Johns
Hopkins. Most physical research would involve laboratory scale physics and chemistry,
as well as computer simulations, modeling, and analyses of the kind routinely conducted
by climate scientists today. Simultaneously, the institutional research branch would
identify alternative means to regulate and manage SRM use, to include formation of a
specific objective such as presented in the first Element above. The plan would include a
detailed proposal for formation of a control institution to test and regulate the use of
SRM. The plan would ideally be reviewed and accepted by experts from a very wide
spectrum of relevant disciplines (18 months, $3.5 million estimated).
Phase II: Careful real world testing of subscale versions of SRM at gradually increasing
scales to verify any remaining questions and development of revised implementation
plan; appointment and organization of the SRM control organization (18 months).
Phase III: Review research results and propose and take comment on an SRM schedule
of events. This would be the first major action of the international SRM control body. It
would include a reexamination of the objective to ensure adequate global support (18
months).
Phase IV: Solar Radiation Management (SRM) begins under international control
through the SRM control body. Implementation would be transparent and would include
continuing monitoring and reporting of physical effects as well as and semi-annual plan
revisions based on new information gained. Full SRM for the geographic area
selected/world would be realized within weeks of full implementation. Note that if the
quantities are correctly selected, it would be possible to design SRM so that no further
warming of the area selected/world would occur after that time regardless of other
climatic events as long as an appropriate level of particles is maintained.
Phase V: Maintenance of SRM system based on continued comparisons between
objectives (element 1 above) and actual achievements. The SRM program, if effective,
would be expected to continue until no longer needed (when greenhouse gases are
adequately controlled), and could be expected to remain in place for a century

Good morning everyone! I've been out hopping around the net and collecting additional information for this specific topic. In fact, I've found more description about methods of deployment into the atmosphere, since that does seem the higher area of interest for readers on this topic. It's not just about aircraft. Well, not just about jet aircraft anyway.

He has one idea which is somewhat novel. The other method is currently in use across China for climate modification through seeding for precipitation control.

Geoengineering is more properly used as the term for the overall approach to climate modification and control. That includes things like Cloud Seeding, as Britannica notes here...
Thank you! I really appreciate any solid info folks can add to this and my future threads in this topic area.
So long as modest low-level field studies designed to answer these questions are done in an open and transparent manner, we believe they should not be subject to any formal international process of vetting and approval. Countries and firms routinely fly various aircraft in the stratosphere, or send rockets through the stratosphere into space. These activities release significant quantities of particles and gases.
A requirement for formal prior approval of small field studies, just because they are directed at learning about
SRM and its limitations, is probably unenforceable because judging intent is often impossible. Such a regulation would, at best, make conducting modest low-level SRM research extremely difficult and, at worst, impossible
2. An Experiment in Arctic Cooling
Many predict that more severe warming will affect the Arctic and the planet within a few decades.
There is evidence that widespread melting of polar ice about 125,000 years ago contributed to a rise
in global sea level 13 to 20 feet (4 to 6 meters) higher than today’s level. Polar temperatures were
about 5 to 9 degrees Fahrenheit (3 to 5 degrees Celsius) higher than they are today (IPCC, 2007).
Thus, the Arctic seems to be particularly vulnerable to climate warming.
Experiments performed at a scale that is too small to affect climate could yield much information
about potential climate and chemical effects of solar radiation management schemes. Particles
deployed in the lower stratosphere near the North Pole in the late spring would be expected to be
substantially removed from the stratosphere in the next polar winter, so unexpected adverse effects
would be unlikely to persist for more than a single year.
