Reading through the RealClimate discussion of the recent Schmittner et al. paper on ice age climate sensitivity (http://www.princeton.edu/~nurban/pubs/lgm-cs-uvic.pdf) I came across the following claim:
“without the role of CO2 as a greenhouse gas, i.e. the cooling effect of the lower glacial CO2 concentration, the ice age climate cannot be explained.”
Thought this might be worth a thread.
The paper isn’t difficult to follow, and gives a useful insight into the current state of play with models which are used to attempt tasks such as trying to determine the climate sensitivity (assuming it is linear), from long time span runs. This one runs from the Last Glacial Minimum in temperature around 23Kyears ago.
