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?

  • $\begingroup$ That is a strange comparison, considering the rate of predicted global temperature change. If that is in the order of degrees in maybe 200 years, versus a few degrees over 100000+ years, what's there to compare? $\endgroup$ – Jan Doggen Apr 24 at 15:18
  • $\begingroup$ @John - perhaps I'm missing something, but I didn't see anything in that link that's related to Milankovich cycles. $\endgroup$ – Mark Apr 24 at 20:21
  • $\begingroup$ "solar forcing" is the sum of the effects from the Milankovitch cycles $\endgroup$ – John Apr 24 at 22:14
  • $\begingroup$ @JanDoggen, it is not a strange comparison - the low points of milankovich cycles and the high points of CO2 levels are essentially antagonistic in their effects of global temperatures - I was wondering what their relatives strengths were, which is not the same as rate of change $\endgroup$ – Amphibio Apr 24 at 22:47
