Those "clouds" are incredibly tenuous. They pose no danger to the Earth.
However, yes, they will affect the Earth.

Everything that we can detect in space affects Earth to a large degree. We don't notice because we don't have any baseline with which to compare.
Here is a “thought experiment”:
Imagine that you can go back in time and make a small change and then compare the resulting situation with the way things are today without that change. You go back in time to 2 years before you were born and the only change that you make is to deflect one single photon to Earth that otherwise would not have reached here.
That photon is absorbed by an atom in the atmosphere and changes the energy of its electrons, changing its frequency and Brownian motion. That atom constantly bumps other atoms at incredible speed. In minutes, every atom of the entire atmosphere is in a slightly different location. That would seem to make no difference.
Consider that before a person’s conception, millions of sperm are jostling around until one reaches the egg. The change of one atom may not affect the sperm enough to change its course, but “all” of the atoms are in different arrangement. The bumping and jostling is completely different. After the change you made, it is very unlikely that the exact same sperm would have reached the egg. A person may result, but not the same person with the same DNA. Jostling during DNA recombination would also be a factor. This type of change also affects every other living thing on Earth.
When you compare the resultant changes with the way the Earth is without those changes, the difference will be enormous.
