Is AGW Delaying A New Ice Age?
No it is not. I get this understanding from my favorite climate change graph, AllPalaeoTemps(first attachment). Please notice the change in scale as it approaches the present.
If you define ice ages as the low points of the last million years and interglacials as the peaks over the same period then there is
absolutely no way (unless the tilt and wobble of the earth are drastically altered by the changes in water weight distribution) that human induced climate change will prevent the next ice age. We could release all fossil fuels remaining into the atmosphere if you want. In 10k years all that will be back on the ground. Changes in earth orbit and behavior will force an ice age on us.
If you were to travel 135k years into the future to the next interglacial and make the AllPaleoTemps graph it would look strikingly similar to this one. Just one more tick after the peak we call the Eemian. I would imagine that the last tick would look slightly different, with two temperature peaks. One peak at the beginning of the interglacial, that represents the natural warming that led to the interglacial, and another peak at the end, that represents AGW. Regardless, both peaks will ultimately be overpowered by the Milankovitch cycles.
I would like to emphasize that the next ice age is of no concern to either me or many generations after me. Human induced global warming is. To be fair, very rapid melting of the ice caps could cool the oceans enough to precipitate a very temporary ice age, but by that point, who cares.
