Well, yes, actually, absence of correlation implies the absence of causation. At least via the method you are examining for correlation. Correlation is not causation, but it is a prerequisite of causation. If you did a study where people smoked a cigarette and then were screened for lung cancer, you would find no correlation and thus correctly conclude that smoking a cigarette does not cause lung cancer. But there's still a relationship between them, as you could perform a study and find a strong correlation between a long term history of cigarette smoking and lung cancer, which when combined with further biological evidence would cause one to conclude that long-term smoking habits cause cancer.
Similarly, this absence-of-correlation would strongly imply that cosmic rays do not directly impact cloud formation. There might be some other round-about way in which it impacts them, I dunno sea bass absorb the rays which gives them gas which drifts up into the atmosphere and seeds clouds. But you'd have to find a correlation between that mechanism and clouds formation.

I might be wrong, but it seems an awful lot like someone observing that each morning when they awaken the sun rises and therefore believes that it is their awakening that causes the sun to rise. Somewhat arrogant, perhaps?
The problem is that we have not built things in the last 100 years or so to account for even the possibility that the climate might be variable. Reluctantly we have begun to acknowledge that it might not be a good idea to build fragile structires in the path of hurricanes. We have yet to begin to acknowledge there might be a risk to building certain types of structures in areas frequented by tornados. The thought that sea levels might change is even further from anyone's mind.
The reality is that the climate has been remarkably calm and forgiving for the last 400 years or so. Much further back than we have detailed history of. What was the climate like in 1200 AD? How about 150 AD? 2500 BC? Sorry, but all we can do is guess from some very indistinct records. We have some evidence in ice cores, some historical documents and some biological evidence. As to where the sea levels were 4500 years ago we have no idea. Clearly, there have been changes because we know, for example, that the British Isles were connected to mainland Europe some time in the past.
Humans have been around for perhaps 4.5 million years, in one form or another. The Earth's climate has a history of hundreds of millions of years before that and again, we have only the faintest idea of what it was like.
Assuming the climate is going to be the same tomorrow as it was today is a reasonable expectation. Things do not change on that scale very quickly. However, assuming the climate will be the same in 100 years as it was 100 years ago is provably false over periods of time where we have pretty decent records. George Washington dragged heavy sledges across the frozen Delaware River which is impossible today because the river doesn't freeze.
Trying to terraform the Earth to keep the climate the same way it was before is a pointless and futile exercise. Beliving that humans can control the climate is an arrogant statement that is provably false. The climate is going to change and there is nothing we can do to change that fact.

For example, the average temperature from year to year are being compared to another not to the absolute temperature. What the data shows isn't just that the earth is getting warmer (that has happened before), but that the rate of climate change is much faster than in any previous period in the last several million years.
This has nothing to do with the temperature of the earth in general. No one is using a thermometer in cities and averaging them out. What they using are polar snowfall thickness, air pocket analysis, vegetation studies, etc.
Again, temperature is relative and being used for comparison. Temperatures are not absolute. In this vein, a change of few degrees by comparison changed the Sahara a few hundred thousand years ago from a tropical forest into the desert.
