age age-and-aging almost carbon changes documented enormous entirely ice increase last levels ocean seem supported warming
The warming at the end of the last ice age, about 10,000 years ago, was supported by the disappearance of enormous ice sheets, a one-third increase in atmospheric carbon dioxide levels and changes in the seasonal distribution of the sun's energy. But the abrupt changes we documented during the last ice age seem to be almost entirely ocean driven.

Numerical modeling studies show that similar changes can be triggered by warming associated with human emissions as well.
age atlantic change comparable degrees five ice present records reveal total
The records reveal a large, two to five degrees Celsius temperature change in the subtropical Atlantic Ocean. That's comparable to the total change between the ice age and the present day at the same location.
changes clear evidence large last polar rapid undergoing warm
What is new here is clear evidence that the warm Atlantic, like the polar Atlantic, was undergoing very large and very rapid temperature changes during the last glacial period.
