We as temporal shit clingers on this rocky planet have the incapacity to realise beyond our own existence the damage we can add to that natural cycle. Life is not permanent and we as a species are no different. Your point is probably not a denial of global warming but is instead now framed in the position of, "what's it matter anyway - the planet has cycles we cannot control". And unfortunately you are quite correct. The planet has a way of doing what it pleases, as does the sun, the magnetosphere and other such cosmic entitities that dont really care what we do, and dont care when we die off.
However, it would be quite nice and thoughtful that if the natural destructive geoglacial cycles were to resume in a few thousand years from now, that we could at least not fuck things up BEFORE then? You know, focus on finding solutions to the problems that will hit us hard one day.
The irony. You say that science is benefitted by a skeptical view and that it is myopic to ignore the data. The data has not been ignored and the vast majority (even from companies like Exon in the 70's) understand that the climate is accelerating faster now than it has done for centuries and that humans are the 'likely' contributor to that model. Just because there are one or two outliers, does not make it a worthy debate.
Also, the EPICA graph has errors due to compaction of ice and CO2 being 'squeezed' out. Article here to explain:

Notably - they also spent millions to debunk the science. Obviously - it still has a knock on effect and many people still doubt the science because (like Bob Dole who claimed milk was a carcinogen just like tobacco) powerful American lobbies make the masses confused.

And it is so amusing that people think those ultra rich corporations who rely on the product which is at the forefront of the cause of warming are telling you the truth.
One fucking word for those that haven't learned the lesons of the past. Tobacco.
