"we know very little about the causes of climate change" Wrong. We know a lot about the causes of both NAGW and AGW. Living in the test tube of the latter, we are learning more about the effects of the latter every year.

There is NO other reason to think that the minor warming (approx. 0.75 degrees C) we have seen in the last 150 years is anything but natural variability, a slow continued exit from the Little Ice Age. And there are cycles within cycles. Where much of the nominal warming in the past 150 years can be attributed to rebounding out of the LIA, there is the larger glacial/interglacial cycle at work too. And we are at the tail end of an interglacial period. Again, where you would expect some warming and some reduction in polar ice coverage.
