Quote from drjekyllus:
"Many materials can appear in an ice core. Layers can be measured in several ways to identify changes in composition. Small meteorites may be embedded in the ice. Volcanic eruptions leave identifiable ash layers. Dust in the core can be linked to increased desert area or wind speed.
Isotopic analysis of the ice in the core can be linked to temperature and global sea level variations. Analysis of the air contained in bubbles in the ice can reveal the palaeocomposition of the atmosphere, in particular CO2 variations. There are great problems relating the dating of the included bubbles to the dating of the ice, since the bubbles only slowly "close off" after the ice has been deposited. Nonetheless, recent work has tended to show that during deglaciations CO2 increases lags temperature increases by 600 +/- 400 years [9]. Beryllium-10 concentrations are linked to cosmic ray intensity which can be a proxy for solar strength." Wikipedia

Okay you can shut up now.
Science in the hands of a fool...
1 - This only applies AFTER CONTINENTAL ICE SHEETS ARE MELTING AWAY:
de·gla·ci·a·tion - n. The uncovering of glaciated land because of melting or sublimation of the glacier.
2) Global temperature rises quickly when the ice melts away
3) CO2 rises much more slowly for several reasons, as the followng extracts indicate:
A) "There are many parts to the puzzle of how atmospheric CO2 changed between glacial and interglacial variations. A simple start is in ocean temperature, where we know from basic chemistry principles that a colder ocean would be better at âholdingâ more CO2 (since gas is more soluble in cooler water), thus lowering atmospheric concentrations. Because so much fresh water was locked up in ice, the glacial oceans were saltier than today by a few percent, which reduces the solubility of CO2 gas in water. "
b) "The coral reef hypothesis asserts that carbonate production on newly flooded shelves contributes importantly to the rise of atmospheric carbon dioxide during deglaciation. The pattern of reef growth that emerges suggests that emission of CO2 resulting from carbonate production was important particularly during the late stages of deglaciation"
c) "Upon melting of glacial ice sheets, reestablishment of forests and grasslands caused a Gradual rise in global CO2 levels"
The one who should be shutting up, is one who blindly cuts and pastes things he obviously did not understand
