Short Game 1 question. How many degrees of temperature rise does that chart translate to?

The way I interpret that graph is that every 100,000 years or so the CO2 level increases and we have an ice age. If I were to look at the increase in CO2 levels in the last few years according to the chart I would expect another Ice age only colder. This would place it right on time with that 100,000 year cycle.
The problem with geologic time is reliability. First hand knowledge is always better than extrapolation of data. Ice cores are not the most reliable information. What may have been true in one area may not be reliable 1000 miles away.
The East Coast ice sheet of Antarctica has increase in depth while the West Coast has not gained. My theory is since there are lakes under the Antarctic ice and the surface temperature is always at a minus temperature volcanic action is providing the heat. There is active volcano's in the region.
What we don't know about Climate is obvious. What we think we know is dubious. It's only been sixty years since the Jet Stream was discovered. By accident.
Snow and ice layers are laid down unevenly at different altitudes.
The Greenland Icecap gained 300' over the planes mentioned below in a 50 year period.

Sorry about the ramblings but after awhile anything about Climate change is nothing more than rambling.

New mechanism of past global warming? Thawing permafrost 50 million years ago led to global warming events
Posted: 04 Apr 2012 10:38 AM PDT
Climate scientists have proposed a simple new mechanism to explain the source of carbon that fed a series of extreme warming events about 55 million years ago, the Paleocene-Eocene Thermal Maximum, and a sequence of similar, smaller warming events afterward.

The following does not relate to the foregoing but is a comment on much said here.
Taken sufficiently out of context you can imply most anything from any source. Take for an example some Bible guotes (if not stated exactly I'm close.... been a while since I read those passages.
"...Judas Iscariot went straightway and hanged himself", "do ye therefore likewise" "what you do, do in haste."
It's scriptural... from the Bible, it must be a valid idea.

Climate change has increased vegetation in Arctic tundra regions. According to a recent study, the increase in vegetation in tundra regions may further accelerate global warming.

Well, it doesn't tell us that, does it? It only correlates to the rise in temperatures we are seeing in the present and those rises over recently past decades. We can make of it what we will.
I posted it to compare our current PPM spike of CO2 to the earlier peaks shown in the ice cores. The word, "unprecedented" comes to mind.

Standard blah blah is water from comets.
Where is the meteor water in metallic or stony meteorites. Ya got a cite?

Which came first the "Chicken or the Egg"? You have to have heat to melt the Permafrost.
I do like the hypotheses that global tilt is a factor. One hypotheses is that the Antarctic gets heavy enough by accumulation of snow and ice to affect the global tilt.
