I read the link and you are full of crap. Nothing about us being in the middle of an interglacial, and the graphs had no details for the present Anthropocene. The only useful item it did say is that the WAIS could collapse with present AGW, within a 500 year time span and accompanied by EAIS melting, leading to up to a 7 meter sea level rise. It also said the record has numerous 1Ma gaps. The main site link worked, and the guy there is quoted as saying the Antarctic is heading back toward the way it was millions of years ago(i.e. less ice/no ice), so it is good to study the way it was.
The longest interglacial in the past was about double the normal 10-15K years. The Milankovich Cycle(~100K years) is NOT exactly in synch with the axis tilt wobble cycles(~23K years, 11* tilt wobble), and that is what makes up the majority of variation.
The present interglacial was on a cooling trend as the Earth's axis tilt went past 22* to the max of 23* and the maximum ellipticity of orbit of the Milankovich cycle coincides, this time. In 2000 more years, we should have been entering the ice age epoch, but will not because of HGHGs. You can compare it to the 400PPM CO2 of over 4 million years ago, but the continents are moved and CO2 will go far beyond 400PPM. The high northern latitudes are already at 400PPM.
So with AETM we get another 22' of sea level rise to top off the over 500' rise from early in the interglacial. Humans will have died off and be in small numbers. If the Yellowstone super volcano erupts in 2K years it will cool it only 1/3 of the way, and only until the aerosols settle out. What could have helped the start of the ice age will do nothing to stop a period of skipping two complete ice ages, until the CO2 is re-sequestered. Then it will be several million more to get back species diversity, and probably no humans left to study the WAIS.
PS: look at your last chart----5 glacials in 500K years=100K years for each with slight variability from the difference between the tip wobble cycle and the elliptical orbital cycle. This one is coming right on at the tip max and ellipse max in 2.4K years, but it won't happen with a methane turnover event that the Earth is heading toward because of human pollution from HGHGs. Shove your BS.
