By all means I support NASA and NOAA and others doing pure science for understanding... but NO POLITICAL oriented science to make these globalists money and damage our planet through geoengineering.
To consider geoengineering is ridiculous. Better to switch to local community grown biofuels, solar, wind, and other renewable resources that do not harm the planet.

Ok. Then where should the money for the research come from? The oil companies? I don't think so. The money that BTS talks about comes from us, by way of the government. That same "political oriented science" is the science that found that there are mitigating factors that had not been considered. Maybe that "political oriented science" will find out that the current warming trend will be softened by other unconsidered factors. But there is no way to know that without doing the science. BTS doesn't think it's worth it. I disagree.

I don't see many (if any) who are considering the use of geoengineering (more specifically, SRM) much less advocating for it. I see a small effort to explore the ramifications of it and to keep an open dialog about it. A tiny fraction of the small amount being put into climate research is devoted to geoengineering research. A smaller amount of that is spent on SRM research.
I agree alternative energy should be explored. It is being explored. The problem is that, at this point, it costs more than what we have been doing and there are a lot of short sighted people who don't want to pay the price. Do you have the money for a photovoltaic system? I don't. Does your community get enough sunlight and wind to furnish its energy needs year round? Mine doesn't.

How does the magnitude and rate of human impact compare
with the natural variability of the Earth’s environment? Are
human effects similar to or greater than the great forces of
nature in terms of their influence on Earth System
functioning?

And at about that same time we saw the introduction of more and more and more high-bypass turbofan engines.
THAT is the reason for the more prevalence of more persistent contrails.
Period.
This has been explained countless times, already. Use the key words (high bypass turbofan contrails) in an Internet search engine, to find more information.
About two hundred thousand people can be found in the stratosphere at any one time, sitting on airliners.
The stratosphere is very cold, and the hot gases from jet engine exhaust behave differently up here than closer to the ground.
However, aircraft emissions are unusual in that a significant proportion is emitted directly into the upper troposphere and lower stratosphere where they have an impact on atmospheric composition. This makes airplane emissions particularly potent compared to other emissions.
It’s a win-win situation: Take sulfur out of jet fuel and you can improve air quality and cool climate at the same time.
Burning sulfur-laden jet (or diesel) fuel produces sulfate. Sulfate particles down near the ground get lodged in your lungs; high in the atmosphere during the day, they act like tiny mirrors that scatter solar radiation back into space. Sulfate spewed from volcanoes, for instance, is well known to cool the atmosphere. So, removing sulfur from jet fuel might actually cause more warming—or so it seemed.
The end result of Unger’s simulations is that desulfurization of jet fuel produced a small, net cooling effect.
Unger points out that the aviation industry is currently responsible for about 3% of all CO2 emissions from the burning of fossil fuels. But when you tally up all non‐CO2 effects, aviation’s share anthropogenic climate forcing may be as high as 14%.

Sulphur and how cooling it is or isn't may soon go the way of other sunscreens and become another experiment that just didn't work out but did produce life altering effects. Another oh well moment.
Time To Take Sulfur Out Of Jet Fuel

It is thought that between 20 and 50 million tonnes of sulphur enters the atmosphere from the oceans each year.
so while IMO reduction in aviation-produces sulphur pollution is almost certainly a good thing, it is not anywhere near being a magic bullet.
A recent increase in the abundance of particles high in the atmosphere has offset about a third of the current climate warming influence of carbon dioxide (CO2) change during the past decade
the reasons behind their increase remain the subject of ongoing research
Since the year 2000, stratospheric aerosols have caused a slower rate of climate warming than we would have seen without them
the amount of aerosol in the stratosphere has been in something of a “background” state, lacking sharp upward spikes from very large volcanic eruptions
Stratospheric aerosol increased surprisingly rapidly in that time, almost doubling during the decade

The Space Shuttle Orbital Maneuver Subsystem (OMS) is the largest engine to be fired in
the F-region ionosphere. The OMS thruster provides 10 kg/s of exhaust materials exiting
at a speed of 3 km/s. The OMS nozzle can be pointed in the ram, wake or out-of-plane
relative to the Space Shuttle orbit.
