The phrase
"glacial inception" refers to the starting point or beginning of a glacier. It describes the moment when ice begins to accumulate and transform into a glacier over a long period of time.

The argument in the new paper is interesting, attempting to use the paleoclimatic record to quantify the threshold
for glacial inception.
@ 31: Also suggestive (but hardly conclusive) on Milankovich, Jochum et al 2011 (draft paper)
got glacial inception in a CCSM4 model by subjecting it to orbital forcings from 115 kya.
Extreme weather is the name of the game when seven of the past eight interglacials
underwent glacial inception at their half precessional ages.
«What we show in our paper is that we escaped
the glacial inception naturally, thanks to a proper combination of Earth's orbital parameters and natural CO2 concentration.»

Here we simulate
the glacial inception and early growth of the East Antarctic Ice Sheet using a general circulation model with coupled components for atmosphere, ocean, ice sheet and sediment, and which incorporates palaeogeography, greenhouse gas, changing orbital parameters, and varying ocean heat transport.
