So around July of 2014 the world average CO2 PPM will be 400.
"2009). The direct evidence of WAIS stability from the ANDRILL cores shows that it is highly sensitive to climate warming, so man needs to stabilize the climate while we still have a little time.[/i]"
WHILE WE STILL HAVE THE TIME, and all denialism has done is waste that time.
That was the same year tundra scientists warned that we were at the tipping point of the tundra methane self release positive feedback loop.
I call it human inertia to change.
Or maybe more like that goat breed that stiffens up when frightened and falls over.
From Wayne's post:
"That paper does have some interesting information though."
"'Data from the core indicate the advance and retreat of WAIS numerous times in the response to the climate changes chiefly driven by Milakovich cycles (changes in Earth’s orbit, tilt and wobble of axis, which differes the amount of solar radiation). Approximately four million years ago when Earth’s temperature was 3°C warmer than present and Co2 levels were 400 parts per million, WAIS was mostly submerged by ocean. (Naish et al, 2009).
<snip>
Results from ANDRILL show that WAIS had collapsed in the past when the temperature is 3°C warmer than today and CO₂ concentrations are 400ppm (Naish et al, 2009). This is most likely going to occur again by the end of the century (IPCC, 2007). Results from incorporating ANDRILL’s data into prediction models show similar collapses of the WAIS and 7 metre increases in sea levels (Pollard & DeConto, 2009). Collapses of the WAIS have been abrupt (~<500 years) in the past, thus could be just as abrupt today, but large uncertainties still remain (Naish et al., 2009). The direct evidence of WAIS stability from the ANDRILL cores shows that it is highly sensitive to climate warming, so man needs to stabilize the climate while we still have a little time.'"
I guess you missed that, spot.
