Researchers report that mean ocean temperature data derived from noble gas ratios in Antarctic ice cores reveal that the global balance of radiative energy was positive, typically around 0.2 watts per square meter, for around 10,000 years during the last deglaciation period; variability in the record suggests that reductions in North Atlantic deep water formation may have increased the heat uptake, according to the authors.
