Yet with all this going on, CO2 is higher than it was in the past and the temperature is still 3-5C cooler, with only a 1.2C rise in about 150 years compared to 3-5C (and higher) rises in shorter time spans of a decade or less in the past, clearly showing CO2 is not the demon we have been led to believe, the only thing that we have done to increase the CO2 in the atmosphere to the extent it has is cut down the damn trees to make this wonderful world for a 1/4 of the population that will never let it go while the other 3/4 starve and their land is used to feed, clothe, power and make all those other glittery goods like the PCs we are all using to type on, or the gold in some peoples teeth or around their necks or the diamonds on the end of our drills and in our saws or again around some peoples bloody necks.
Where did anyone get accurate decadal data that far back? The error bars for the date alone are larger than that for any long term reconstruction, much less the temperature.
The arctic Wayne, they have refined the resolution in the way they study the cores when using O18 instead of gases, as we all know show massive uncertainty due to the squeezing of them upward and away from the layer they settled in.
"During the last glacial maximum, 25 000 to 14 000 bp,
annual temperatures over Greenland are believed to have
been 25 °C colder than at present (Cuff ey et al., 1994;
Cuff ey and Clow, 1997; Dahl-Jensen et al., 1998), sea
level to have been 120 m lower than at present (Lambeck
et al., 2002), and the volume of the Greenland Ice Sheet
to have been 140% higher than at present (Huybrechts,
2002; Lambeck et al., 2002).
Th roughout the last glacial period, the climate was very
unstable with 25 rapid climate changes, termed ‘interstadials’
or ‘Dansgaard-Oeschger events’ (DO; Figure 1.3).
Th e area and volume of the Greenland Ice Sheet increased
to 40% more than the present area and volume. Th e north
Atlantic region and the Greenland Ice Sheet experienced
rapid temperature increases of 10 to 15 °C occurring over
a few decades (North Greenland Ice Core Project members,
2004; Landais et al., 2005; Steff ensen et al., 2008) together
with sea level increases of 5 to 20 m (Siddall et al.,
2003). Th e rapid changes are believed to have been connected
to enormous surges of ice into the ocean, especially
from the Laurentide Ice Sheet over North America. Aft er
the abrupt warmings during the D-O events the surface
temperatures gradually cooled over 1000 to 5000 years, before
the next rapid warming occurred. Th e contribution of
the Greenland Ice Sheet to the sea level rises that occurred
during these rapid warming events is not known.
Aft er the glacial period, the climate warmed into the
present interglacial period, the Holocene, and the coastal
regions around Greenland experienced isostatic uplift of
up to 100 m in response to the retreating ice (Letréguilly
et al., 1991; Weidick, 1993; Huybrechts, 2002).

"On the other hand, very rapid warming is known to have occurred at times; for example, Anklin et al. (1993) report warming by 7 °C over a few decades in Greenland at the end of the Younger Dryas and the Intergovernmental Panel on Climate Change (IPCC 2001a) concludes that warming may have occurred at rates as large as 10 °C/50 years for a significant part of the Northern Hemisphere at this time."
Flying in the face of climate change: a review of climate change, past, present and future
I can't find the papers that have the within a decade, but again I point you to a quote from the ANDRILL paper I cited in another post
"Ice core data from the last glacial period in Greenland show that change at that time could proceed rapidly - with several increases of more than 10ºC within a decade to possibly one to two years (Fig. 3.13); comparable changes in Antarctica were much slower."

Talking about error bars, how narrow would error bars become when data that is collected daily (and adjusted) gets converted to monthly (and adjusted), 3 monthly(and adjusted), yearly(and adjusted), then 5 yearly(and adjusted), then 15 yearly (and adjusted) like all the pretty data that is used to push the current warming cycle and CO2??
You do realize the HUGE error in comparing local changes to global changes in such a fashion do you not? You are taking the current global change and comparing it to a local change in trying to say the historical changes were greater. I am sure we could find local changes now that would be greater than the localized changes you are comparing, but that would give us nothing with the comparison.
The error bars ARE small in comparison to reconstructions of large areas even back 1000 years. You have no large area reconstructions with which to compare similar data so there is no real comparison to make.
