This has been confirmed by others. In case you missed it, Shaffer, Gary, 2009 (“Long time management of fossil fuel resources to limit global warming and avoid ice age onsets ,” Geophys. Res. Lett., 36, L03704, doi: 10.1029/2008GL036294 ), suggested that we if we saved the remaining fossil fuels, we could head off the next few ice ages by burning on the appropriate orbital schedule (although I have heard people suggest that we could manufacture much more potent greenhouse gases to do the same job).
