I understand that we are, in all likelihood, towards the end of an interglacial period (the holocene). What I'd like to know is, what has a stronger effect on global temperatures - the low point of the combined milankovich cycle, or CO2 levels of a certain amount (e.g. 600ppm, 1000ppm, etc)?
Could current greenhouse gas levels (around 410ppm) prevent us from entering the next glacial period, or will we enter it no matter what we do?
