 Read your own subject line and give it a couple of seconds of thought.
The CO2 level was high 30 million years ago and is only just now catching up to that level now. What happened in the meantime? Why, it went down! Surely the result of passionate activism by all the environmentally conscious people of that era, right? Oh, wait, THERE WERE NO PEOPLE OF ANY KIND 30 million years ago!!!
 So how did all that CO2 get into the atmosphere in the first place if there were no people and what process made the levels get lower after that peak 30 million years ago? What makes you think that same process won't come into play now?

I posted to scotch any suspicion that, because we've forgotten about global warming, it's forgotten about us.  The CO2 greenhouse effect appears to be among the less controversial bellwether phenomena.
As to whether there's a CO2-fairy who steps in to tweak the thermostat whenever things get toasty, you should note that 30 million years ago just happens to match today's CO2 level ...and at that time the level was *dropping* from much, much higher (whereas today it's rising).
But, like you, I derive my scientific view from that of "experts"...and, afaics the genuine ones seem, if uncertain about magnitude, nevertheless unanimous about direction.  Here's a short take answering your question:
