>>As can be clearly noted, we have been on a much longer trend downward trend overall across the last 3 million years with the 100kyr cycle deepening and becoming more pronounce on the downside. Entertaining the strong concept that continuation in the established 100kyr periodicity is hardly at an end with deep glacial eras yet to come.<<
Interesting thought - there is something we can do about global warming (invoking a mild nuclear winter) - I wonder what we'd do for serious global cooling - burn forests just for the CO2?

CO2 levels 20 times higher than today have been accompanied by deep ice ages at global average temperatures more than 10o C lower than today. CO2 from burning the forests is unlikely to help much against the cooling effects associated with deep ice ages. The change in earth's albedo (reflectivity) just from increasing the size of ice caps is much greater effect.
