Where can I find a graphic presentation of the variation of average
global temperatures over the past 100,000 years ?

Is this the sort of thing you had in mind:

Clarification of Question by rayhatley-ga on 04 Jan 2006 17:12 PST

I posed the question "Where can I find a graphic presentation of the
variation of average global temperatures over the past 100,000 years
?" to which  pafalafa-ga provided a query and link to a graphic.  The
graphic did provide a generalised (if somewhat stylised) idea of the
estimated average temperature changes over the past 10+ million years.
 I am hope to obtained more detialed data and/or plots on this subject
(scientific journal quality) - perhaps showing level of confidence
information as well - and more specifically for the past 100,000
years. Hope that provides a more clear idea of what I'm after. 
Thanks, Ray Hatley

You're asking for an awful lot packed into one graphic illustration. 
You might want to look over the sources listed here:


http://www.ncdc.noaa.gov/paleo/recons.html


to get an idea of what sorts of long term records are actually available.


Let me know if that helps at all,

paf

http://www.koshland-science-museum.org/exhibitgcc/historical02.jsp

has a graph for the last 300,000 years for Antarctica - but it doesn't
have the other information you are interested in. It does have some
comments of interest, but not much on details of measurements. (The
green boxes numbered 7 through 12 have some very basic information on
what the temperature is derived from - but it's definitely not
detailed.

http://cdiac.esd.ornl.gov/trends/temp/vostok/jouz_tem.htm

describes how past Antarctic temperatures mentioned in the previous
comment were determined from isotope ratios. The amount of the heavier
isotopes of oxygen and hydrogen in ice depends on the temperature.
There aren't any error bar or standard deviations, though.

http://gcmd.nasa.gov/records/GCMD_CDIAC_VOSTOK_TEMPS_TRENDS.html

has a link that will let you download the data for Antarctica for the
last 420,000 years.

links to the 1987 Nature article determining the Antarctica
temperatures for the last 160,000 years. The article, though, costs
$30 US.

----------

http://chemistry.beloit.edu/Warming/pages/reference.html

references methods of estimating global climate and factors that
affect climate. Most are regarding current measurements, though. 
There are, however, links to limits of glaciation at various times in
the past.

www.greenpeace.co.uk has a lot of information on climate change...
