Jack, did you read the URL that I gave?  I thought not.

I twice tried to reproduce here the figure referenced there, but I 
don't know how I guess.  The data shows repeated global warming and 
glaciations which follow those warmings.  I don't doubt that we are 
currently experiencing another warming period.  I still wonder what 
its cause is.  I think that there is evidence that the cause is 
natural, but I don't fully understand the explanations. But if the 
data given there is correct, we are on the verge of another 
glaciation.  I can see that the current warming is _accompanied_ by 
an increase in greenhouse gasses, but there doesn't seem to be proof 
of the _cause_ of the warming.  Just as there doesn't seem to be a 
convincing proof of the cause of previous global warmings -- which 
clearly were not due to greenhouse gasses -- at least not greenhouse 
gasses produced by humans.

My problem, Jack, is that you seem to avoid, totally, current 
research on the subject.
