Yes. I recall a colloquium from some years back where the speaker showed how satellites could track ships because of the clouds formation from the particulates in the smoke/exhaust.

 

Hard to say whether cloud formation is detrimental without including the context. There are undoubtedly some positive and some negative aspects of it.

Contrails of jet aircraft are a good example, I suppose. Also silver iodide, potassium iodide, or dry ice particles are in common use for deliberate "cloud seeding" attempts at rain production, commonly using rockets or aircraft. Very popular in China, I understand.

I recall the Global Cooling hypothesis, your succint summary is admirable. This has been demonstrated by volcanic eruptions and formed the foundation of the "nuclear winter" speculations of yesteryear, if I am not mistaken.

Yes, apparently it is mitigating somewhat the full brunt of the warming trend.
