This major change in ocean circulation, along with a climate that had already been slowly cooling for millions of years, may be what led to
ice accumulation most of the time — but also to climatic instability, with flips every few thousand years or so between warm - and - wet and cool - and - dry.

I got a
most probable value of 1.55 C / doubling, a 17 % to 83 % range of 1.41 C to 3.27 C / doubling, and a 5 % to 95 % range of 1.18 C to 6.2 C / doubling... not far from your values (but I assumed a little higher total heat
accumulation, including deep ocean uptake equal to 10 % of the 0 - 2000M value, and some additonal heat for
ice melt and land mass warming).
Indeed
most of the warming is recorded in the Arctic but not due to hear
accumulation but due to heat ventilating through open waters and thinner
ice.
The difference in CO2 levels between all
ice cores drilled in Antarctica with the
most extreme differences in snow
accumulation and temperature is not more than 5 ppmv for the same average gas age...
High
accumulation ice cores have a better resolution (about 60 - 80 years) and because of the one - way CO2 increase, the
most recent layers only have a 10 years
ice - gas age lag and a 5 years resolution.
The
most common causes for ankle injuries in slip and fall cases is as a result of snow and
ice accumulation on a poorly maintained surface.
