We are reading all this doom and gloom about the collapse of the Antarctic Ice shelves, as if this is unprecedented in human's time on earth. It isn't.
The George VI ice shelf lies at 70 degrees south. As of today, this shelf is not showing signs of collapse due to global warming. The George VI shelf is 100 to 500 meters thick. It's location is shown on the picture below.
The author's point out
"Some studies in the northern Antarctic Peninsula suggest iceshelf
collapse in the mid-Holocene (Pudsey and Evans, 2001). To date, ice shelves farther south (south of 708S) have shown no catastrophic breakup, although some ice-shelf fronts are in retreat. This paper presents the first evidence of an early Holocene collapse of one of these more southern ice shelves." M. J. Bentley, “Early Holocene Retreat of the George VI Ice Shelf, Antarctic Peninsula,” Geology, 33(2005):173-176, p. 173
They further note the time of its disappearance.
"“Our core chronology shows that the George VI Ice Shelf disappeared in the early Holocene, with the onset of collapse by 8170 14C yr B.P. (9595 cal. yr B.P.) and complete reformation by 7300 14C yr B.P. (7945 cal. yr B.P.). This coincides with deglaciation in many Antarctic coastal areas (Ingo´lfsson et al., 1998), and follows deglaciation of the western Antarctic Peninsula shelf (Anderson, 1999). The record of the George VI Ice Shelf collapse immediately postdates ice-core evidence of a widespread, sustained early Holocene climatic optimum (Masson et al., 2000; Masson-Delmotte et al., 2004) ca. 11–9.5 ka (Fig. 4). The collapse is also coincident with the influx of Circumpolar Deep Water onto the Antarctic Peninsula continental shelf, as demonstrated in the Palmer Deep marine record (Domack et al., 2001; Fig. 4).” M. J. Bentley, “Early Holocene Retreat of the George VI Ice Shelf, Antarctic Peninsula,” Geology, 33(2005):173-176, p.175
Now, given the 'consensus' that the earth's present temperature is 'unprecedented' what do these scientists conclude?
“Thus, both atmospheric and oceanographic warming occurred immediately prior to, and coincident with, ice-shelf collapse. Finally, the timing of the iceshelf collapse predates collapse at more northern Antarctic Peninsula sites (Pudsey and Evans, 2001), that has been linked to a mid-Holocene warm period (Jones et al., 2000; Hodgson et al., 2004). We have three main conclusions: (1) High-resolution multiproxy sediment records show that the George VI Ice Shelf collapsed in the early Holocene. (2) The timing of collapse is consistent with both iceand marine sediment–core evidence of early Holocene warmth. (3) The collapse of a currently extant ice shelf shows that early Holocene natural ocean-atmosphere variability in the Antarctic Peninsula was greater than the recent, potentially anthropogenically influenced changes.”

My bolding. The reality is that in spite of what the hysteriacs say, today's warming is not as warm as it was 8000 years ago. The science of geology shows it yet they ignore it.
