Geoengineering Test Quietly Launches Salt Crystals into Atmosphere

[ArMaP]

Secrecy indeed... it translates into "[We] don't need anyone questioning our infallible wisdom and knowledge, so best let them remain ignorant until it's over and done with."

Or to "we don't really know what we are doing, so we prefer nobody knows about it unless it's a success".

(From BGR:) The latest extreme climate change solution involves dehydrating the stratosphere

This concept seems based upon the idea that "water" in the atmosphere "acts as a greenhouse gas."  And that if we were to inject ice-forming particulates into the atmosphere we could reduce the amount of 'greenhouse effect' it produces in our climate.  

Not really.

What they say is that water vapour is known to act as a greenhouse gas and the idea is to try to turn some water vapour into ice on the stratosphere, no on the whole atmosphere, as implied in that text.
 

They say there are no cons or side effects to worry about.

Not true. They mention these possible effects:
- Effects of additional clouds generated by the injections, both at the altitude of interest and, potentially, at lower altitudes;
- Implications for feedback to the large-scale global circulation;
- It may affect the recovery of stratospheric ozone (in a positive, yet negligible, sense for the current climate);
- Depending on the technological approach considered to inject INP, direct emissions associated with the effort could vary tremendously but are likely to be absolutely negligible relative to global emissions.

It's the first time I see a reference to that BGR site and I don't like what I see.

We are most likely heading to cold era anyway ? so any aerosols up there would only make ground more colder, a negative thing to me.

"Most likely" is not enough. 

Now we are getting warmer and warmer years, and the proposed "solution" is one that does not last longer than the time the salt crystals and the clouds last.
