| Jan 20, 2021 at 13:17 | comment | added | Amphibio | Thanks Keith, that is very interesting. So it could be said that our CO2 impact as a species, at least up to this point, has done us a favour. | |
| Jan 20, 2021 at 13:14 | comment | added | Amphibio | Jan, I don't think that entering into another ice age would be 'irrelevant'. The effect on human civilisation as it currently stands would be catastrophic. | |
| Jan 18, 2021 at 4:39 | comment | added | Keith McClary | The paper discussed here says that, with pre-industrial CO2, Milankovich would be tipping us into a glaciation about now, but with anthro CO2 there will be no glaciation for 50,000 years. I don't think this is "settled science" yet, though. | |

| Apr 25, 2019 at 7:31 | comment | added | Jan Doggen | Well, as far as the impacts on the environment goes, the Milankovich cycles are irrelevant for us. So this makes it a theoretical question at best. | |
| Apr 24, 2019 at 22:57 | comment | added | Amphibio | In summary, it seems the answer is 'yes', but only if CO2 levels are above a much higher amount, to escape the glaciation cycles...... anyone know what that amount is? | |
| Apr 24, 2019 at 22:51 | comment | added | Amphibio | this video has some interesting info - C02 levels used to be about 1700ppm (?) 50 milllion years ago, and the earth didn't have glacial cycles and ice ages. The big sink of CO2 was apparently the rise of the himalayas and the tibetan plateau - india and china crashing into each other basically - and the carbonation of alll that exposed rock (around 19:30) - youtube.com/watch?v=Yze1YAz_LYM | |
| Apr 24, 2019 at 22:47 | comment | added | Amphibio | @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 | |
| Apr 24, 2019 at 22:14 | comment | added | John | "solar forcing" is the sum of the effects from the Milankovitch cycles | |
| Apr 24, 2019 at 20:21 | comment | added | Mark | @John - perhaps I'm missing something, but I didn't see anything in that link that's related to Milankovich cycles. | |
| Apr 24, 2019 at 15:18 | comment | added | Jan Doggen | 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? | |
| Apr 24, 2019 at 15:08 | comment | added | John | We are already diverging from the what is expected from milankovitch cycle, skepticalscience.com/solar-activity-sunspots-global-warming.htm | |
