That last "really steep climb" from my rough guestimation looks to be an approx 8 deg C change over 6500-7000 years. That is in the ballpark of 0.001 deg change per year.
What we have now appears orders of magnitude faster.

yeah we are stuffing up our very own air, but are we really causing climate change?

Well, we know for sure that we're pumping scary amounts of greenhouse gases into the atmosphere - the likes of which has never occured in history. It's actually harder to imagine that we can continue to so with no effect. Especially since the rate at which we do so is increasing at scary levels - the amount of influence we humans exert is only going to increase dramatically.
Sure - there will still be natural variation, to which we add our own. Left to itself, perhaps the earth was/is going into an iceage in the future - but the thought of a possible 'iceage' thousands of years away seems somehow less pressing than a runaway greenhouse which will have direct impact within the lifetimes of our children.
At the end of day, anyone who right now says they know the answer with 100% surety is being quite brave. But on the balance of probabilties, I would say "yes - it is more likely that we are".
