Like you said, there is too much to list. Particularly at Thomas' site.
There are studies going way back about the effects of contrails on climate. The general consensus is that contrails probably do have an effect but
what that effect is, is very difficult to determine. There also are various patents for various ways of distributing various things at various levels
of the atmosphere in order to "mitigate" global warming.
The studies make sense. The more we can learn about things that may affect our climate the better we can learn about what to expect in the future. The
patents are nothing more than attempts to claim the commercial rights should anyone ever attempt to take active measures. There are thousands of
patents for things that don't work.
The games of politics require that politicians address the concerns of the times whether or not those concerns are valid. Since global warming is of a
certain amount of interest right now it is not surprising that our government is talking about it and talking about things that may be done about it.
Talk is cheap. That's the good thing about it, it's easy to talk.
First, to actually implement the things mentioned requires a huge amount of resources, something that is in tight supply right now. Second, if you
actually look at every paper published about using artificial means of climate control (as opposed to weather control) you will find that they are
loaded with caveats about the unknown consequences of such measures. Putting the two together, it becomes clear that there is virtually no chance
that such measures are being undertaken now or will be at any time in the near future.
